Guppies are social livebearers suited to a prepared beginner, not a fish-per-litre formula. Use a mature filtered aquarium, tested neutral-to-alkaline mineral-bearing water, deliberate sex and population planning, open swimming room, cover and a separation option.
Maintain these water conditions for optimal health and vibrant colors
Blue Neon Female Guppies are female domestic Guppies selected for a blue-toned colour direction. The accepted species name is Poecilia reticulata. Females are usually larger and deeper-bodied than males, with a fan-shaped anal fin and more restrained colour overall, although this variety can show attractive blue in the dorsal fin, tail and parts of the body.
Each quantity on this listing adds one fish selected and sold as female at an approximate 3-4 cm dispatch size. That measurement is a supplier size band, not a guaranteed exact length and not the adult size. Plan for a mature female that may reach about 6 cm standard length. The fish is not sold as a pair, trio, proven breeder or guaranteed virgin female.
"Blue Neon" is a trade colour name rather than a subspecies, wild locality or certified breeder-line claim. Living fish vary: the amount, position and intensity of blue can differ between individuals and may change with age, lighting, background, stress and settlement. The single preserved gallery photograph is a representative product-specific female Guppy, not the exact individual that will be dispatched.
This is a small but active social fish for a mature, heated and filtered aquarium. A practical starting point is at least 60 litres and about 60 cm of swimming length for a small group, with stable medium-hard water, plants or other visual cover, gentle circulation and peaceful companions. Do not buy one as a permanent solitary fish for an uncycled bowl.
| Care point | Practical target | Why it matters |
|---|---|---|
| Adult size | Plan for a female up to about 6 cm SL | The 3-4 cm dispatch band is temporary, and females are larger than most males |
| Group | At least 3; preferably 5+ where space allows | Guppies are social fish and should not be planned as permanent solitary pets |
| Aquarium | 60 L+ and about 60 cm long | Provides more stable water, swimming room, cover and capacity for a small group |
| Temperature | 23-26°C working target | Sits safely inside OATA's wider published 20-28°C range |
| pH | 7.0-8.0 | Guppies generally suit neutral-to-alkaline water better than acidic specialist setups |
| Hardness | 8-18 dGH; 5-15 dKH | Stable mineral content supports osmoregulation and avoids the problems of very soft water |
| Temperament | Peaceful, active and social | Tank mates still need matching water, adult size, feeding speed and fin behaviour |
| Diet | Varied omnivorous diet | Use appropriately sized prepared food with modest suitable frozen or live foods |
These are home-aquarium planning targets, not instructions to force a new arrival rapidly to a perfect-looking number. Test the water before purchase and compare the aquarium with the water in the transport bag on arrival. Our water matcher helps organise temperature, pH and hardness readings so the acclimation decision is based on the real difference between systems.
Poecilia reticulata is the accepted Guppy species in the family Poeciliidae. It is a small livebearing fish originally associated with northern South America and parts of the Caribbean, although domestic Guppies in the aquarium trade have been bred in captivity through many generations and the species has been introduced widely outside its native range. This listing does not claim a wild collection locality.
The words "Blue Neon" describe the expected colour direction of this domestic stock. They should not be written into the Latin name, treated as a subspecies or used as proof that every fish descends from one documented strain. A sensible customer expectation is a recognisable female Guppy with blue-toned features, not an identical printed pattern on every animal.
Female matters here because sex changes both appearance and husbandry context. A mature female normally has a broad, fan-shaped anal fin and a fuller body. A male has a narrow modified anal fin called a gonopodium and is usually smaller and more intensely coloured. At a young dispatch size, development is still continuing, so colour and body depth should not be used alone to judge sex.
This product is selected and sold as female. That is different from promising a particular age, reproductive history or pregnancy state. A female may have had previous contact with males before reaching the customer, and Guppy biology allows stored sperm to contribute to later broods. Ordering a female-only group therefore reduces ongoing male courtship but cannot guarantee that fry will never appear.
You are buying one domestic Blue Neon Guppy selected and sold as female at approximately 3-4 cm. You are not buying a guaranteed exact shade, a photographed individual, a breeding pair, a proven virgin female or a named wild locality strain.
A female Guppy has a streamlined front half, a deeper abdomen and a fan-shaped tail. Compared with a male, she is usually larger, with shorter or less ornate fins and subtler body colour. Blue Neon females can carry blue across the tail, dorsal fin or rear body, sometimes with grey, silver, olive or darker areas elsewhere. The preserved product image shows this female body shape and blue fin emphasis clearly.
Colour is not a fixed digital swatch. Aquarium light spectrum, dark or pale backgrounds, camera processing and viewing angle can all alter the apparent shade. Transport stress may temporarily mute colour, while a settled fish can look brighter after normal feeding and rest. Age also matters: a 3-4 cm juvenile or young adult may not display the same depth or fin development as a mature female.
FishBase records a maximum female length of 6 cm standard length. Standard length is measured to the base of the tail, so the total visual length can be greater when the caudal fin is included. Use the adult figure for aquarium planning. Do not calculate stocking solely from the dispatch measurement or from a generic centimetres-per-litre rule.
A fuller abdomen is not automatic proof of pregnancy. Body shape changes with age, feeding, constipation, internal disease and reproductive condition. A dark gravid area may become visible in some females, but colour strains and lighting make it an unreliable single test. Judge the whole fish: posture, symmetry, scales, breathing, appetite and behaviour are more useful than one silhouette.
| What the listing identifies | What remains variable | How to plan responsibly |
|---|---|---|
| Female Guppy | Age, maturity and previous reproductive contact | Be prepared for possible fry even without a male in the destination aquarium |
| Blue Neon trade colour | Hue, coverage, pattern and intensity | Expect natural variation rather than an exact replica of the gallery image |
| Approximate 3-4 cm dispatch band | Exact measurement and adult growth | Build around a female up to about 6 cm standard length |
| One fish per quantity | Group composition after purchase | Order only after checking the existing group, available volume and filtration capacity |

OATA recommends at least 45 litres for a small group of the smaller Guppy and Molly species. For this listing, we recommend at least 60 litres and about 60 cm of horizontal length for a small female Guppy group. The added margin makes temperature and chemistry easier to stabilise, creates more room for cover and reduces the chance that one active fish dominates every feeding point.
Use a larger aquarium for a mixed community, a large group, retained fry or fish with different swimming patterns. The final stocking decision depends on adult biomass, filtration, surface area, maintenance, plant mass and behaviour. A tank does not become suitable just because its nominal litres divide neatly by the length of each fish.
A filter needs an established population of beneficial microbes before it can process the waste from a new group. Clear water is not proof of a completed nitrogen cycle. Before ordering, confirm that the aquarium can hold ammonia and nitrite at 0 mg/l under its existing load, and that nitrate is controlled by the maintenance routine.
Add livestock gradually. Every new fish increases oxygen demand, feeding and waste. A sudden large addition can exceed the biological capacity of a young filter even when the tank looked stable the day before. Keep a liquid test kit available and test after additions rather than waiting for visible distress.
Guppies need good oxygen exchange and clean water, but a female should not have to fight a powerful current all day. A mature sponge filter, a baffled internal filter or a correctly sized external filter can work. The useful result is steady circulation with quieter areas, not a specific brand or turnover number copied without considering the layout.
Cover exposed intakes where small fry might be present. Keep the surface moving enough for gas exchange, particularly in warm weather when water holds less oxygen. Check that floating plants do not seal the entire surface and that ornaments do not create stagnant pockets where food and waste collect.
Use live plants, smooth wood or safe decor to create broken sight lines around the back and sides. Leave an open route through the middle and front for normal swimming and observation. Dense fine-leaved plants and floating roots can shelter fry, while broader leaves give adults places to pause without disappearing completely from view.
Sand and smooth aquarium gravel are both suitable. The substrate matters less than keeping it free of trapped waste and choosing a depth that suits the plants and maintenance method. Avoid sharp plastic foliage, rough rock and narrow gaps that can catch fins or trap a growing fish.
Fit a secure lid and cover cable or filter gaps. Guppies can jump when startled or when following activity near the surface. Use a regular day-night cycle, with shaded areas under plants or decor. A timer gives a more consistent routine than switching the light on and off at different hours.
Our full Guppy care guide covers general species setup in more detail. Use it alongside this listing rather than replacing the product-specific facts here: this fish is female, arrives in a 3-4 cm band and carries a variable Blue Neon colour direction.
OATA publishes a 20-28°C range for Guppies and Mollies. A stable 23-26°C is a useful long-term target for this listing because it remains inside that range without treating the upper or lower boundary as an everyday goal. Set the final temperature to suit the entire community, and use a thermostatically controlled heater plus a separate thermometer.
Temperature stability matters more than chasing an exact decimal. Avoid placing the aquarium beside a radiator, draught, window or appliance that causes repeated swings. During hot weather, monitor the tank closely, increase surface movement when needed and remember that warmer water carries less dissolved oxygen.
Aim for pH 7.0-8.0 and medium-hard water, around 8-18 dGH and 5-15 dKH. Guppies are often kept poorly in very soft, acidic water simply because they are described as adaptable. Adaptable does not mean indifferent to mineral content. Measure the tap water and aquarium rather than assuming a postcode or water-company average describes the water at the fish's actual destination.
If the source water is already suitable, regular conditioned water changes are usually safer than repeated use of pH-adjusting products. If the water is very soft, choose a measured remineralisation method and apply it consistently to new water before the fish arrives. Do not add salt, shells, buffers or mineral blocks blindly; a rapid chemistry change can be more stressful than a stable value near one edge of a suitable range.
Ammonia and nitrite should remain at 0 mg/l. Both can damage fish before the water looks dirty. Test immediately if a fish gasps at the surface, clamps its fins, becomes unusually still, refuses food or gathers in the filter outflow. Treat a detectable result as an aquarium problem requiring prompt corrective husbandry, not as a reason to medicate the fish blindly.
OATA advises keeping nitrate no more than 20 mg/l above the normal tap-water level. Nitrate is only one maintenance signal; it does not reveal every dissolved contaminant or oxygen problem. Use it with regular observation, substrate cleaning, sensible feeding and water changes matched to the real stocking level.
Defra's current fish guidance says sudden fluctuations in temperature and water chemistry should be avoided. That principle applies both at arrival and during ordinary maintenance. Match replacement water for temperature, dechlorinate it before contact with the aquarium and avoid changing several major parameters at once.
| Measure | Working target | If the reading is unsuitable |
|---|---|---|
| Temperature | 23-26°C | Check heater, thermometer, room heat and oxygen; correct gradually |
| pH | 7.0-8.0 | Measure GH and KH before using any adjustment product |
| General hardness | 8-18 dGH | Use a repeatable measured remineralisation plan if source water is too soft |
| Carbonate hardness | 5-15 dKH | Investigate buffering and source-water variation rather than chasing pH alone |
| Ammonia | 0 mg/l | Treat as urgent; review cycling, feeding, dead material and filter capacity |
| Nitrite | 0 mg/l | Treat as urgent and protect biological filtration while correcting the cause |
For a broader explanation of heater settings and why one temperature does not suit every tropical species, see the tropical fish temperature guide.
Guppies are omnivores. Use a quality small flake, micro-granule or crumble formulated for tropical community fish as the staple. OATA recommends a prepared food with a meaningful algae component, supported by small live or frozen foods such as daphnia, small bloodworm, tubifex or cyclops where these are appropriate and safely sourced.
Match the food size to the fish's mouth. A 3-4 cm female should not have to struggle with large pellets that sink untouched. Crush flake or choose a smaller granule when necessary. Rotate foods rather than relying on one rich item, and do not use colour-enhancing marketing as a substitute for a balanced ingredient list.
Offer only what the group can finish promptly, normally once a day under OATA's general guidance or in two smaller portions if that suits the aquarium's routine and water quality. The correct amount depends on food density, fish size, competition and temperature. A feeding instruction on a tub is a starting point, not permission to leave uneaten food on the substrate.
Spread food across more than one point so quieter fish can feed. Watch the individual, not just the group response. A bold Guppy can make the whole aquarium look hungry while another fish gradually loses condition. Remove persistent leftovers before they decay and test water if feeding behaviour changes suddenly.
Small portions of daphnia, cyclops, brine shrimp or another suitable frozen/live food can add behavioural variety and protein. Rich treats should not dominate the diet. Frequent heavy feeding increases waste, encourages excess weight and makes a possible pregnancy harder to distinguish from overfeeding.
Soft algae and mature biofilm provide natural picking activity, but they are not a complete ration. Blanched vegetable matter may be offered in a tiny amount if the group accepts it, then removed before it fouls the water. Avoid bread, meat, seasoned human food and any item too large to swallow safely.
| Food type | Role | Practical use |
|---|---|---|
| Small quality flake or micro-granule | Balanced staple | Use a size the fish can swallow easily and distribute across the group |
| Plant or algae content | Supports an omnivorous diet | Include through the staple rather than relying only on rich animal protein |
| Daphnia, cyclops or brine shrimp | Protein and feeding enrichment | Offer modest suitable portions as part of a rotation |
| Biofilm and soft algae | Natural picking behaviour | Useful addition in a mature tank, never the only food |
| Finely sized fry food | Supports newborn fish | Use frequent tiny portions only when fry are present and water can stay clean |
Guppies are social fish, but they do not form a permanently tight synchronised school. A settled female group typically explores the upper and middle water, inspects plant surfaces and gathers quickly for food. Individuals may separate for short periods and then rejoin. This loose social pattern is sometimes called shoaling.
OATA suggests keeping at least three Guppies or Mollies together, while FishBase gives a group of five or more. For a new setup, use five or more as the preferred target when the aquarium, filtration and maintenance can support them. A customer adding this fish to an established compatible group does not need to buy a fixed bundle from this listing; each quantity remains one female.
A female-only group avoids continuous courtship from resident males, but it still needs structure and observation. Females can compete for food, and a dominant fish may repeatedly displace another from a favourite area. Multiple feeding points, plant cover and open escape routes reduce that pressure.
Look for controlled swimming, open fins, steady breathing, interest in surroundings and a consistent appetite. A newly arrived fish may hide, remain subdued or show paler colour while recovering from transport. Improvement should follow as temperature, light and water conditions settle.
Persistent surface gasping, rocking or shimmying, clamped fins, repeated rubbing, uncontrolled darting, isolation or refusal to feed are not normal personality traits. Test the water first, check temperature and oxygen, and compare the affected fish with the rest of the group. Behaviour often reveals a problem before a visible lesion appears.
If males are present, OATA suggests two females for each male to reduce pressure on the females. Ratios do not replace space or cover: one persistent male can still harass a female in a small bare tank. Watch the actual interactions and be prepared to separate fish or change the group if one individual cannot rest or feed.
Do not add more females automatically when the tank is already crowded. More fish can spread attention but also increase waste and competition. The better solution may be a larger aquarium, stronger visual structure or removal of a problem male.
A peaceful reputation does not make every peaceful fish compatible. Match adult size, temperature, pH, hardness, current, feeding speed and fin behaviour together. The best companions are small-to-medium community fish that genuinely tolerate stable neutral-to-alkaline, medium-hard water and will neither swallow the Guppy nor nip its fins.
Other domestic Guppies are the simplest social match when the group is healthy and the aquarium can support them. Platies may share similar chemistry and temperament in a larger setup. Mollies often need more space and consistently mineral-rich water, while Swordtails are larger and more active. Each species still needs its own adult-size and group assessment.
Many Tetras, Rasboras and Corydoras are described broadly as community fish, but species within those groups have different water preferences. Do not add a soft-water specialist just because it is small and calm. Check the exact species rather than treating a common name as a compatibility guarantee.
Avoid persistent fin nippers such as many Barbs, aggressive Cichlids, large predators and any fish capable of swallowing an adult female. Long-finned Bettas and other ornamental fish can be unpredictable with Guppies; visual similarity may trigger chasing, while the Guppy's activity can stress a slower fish.
Dwarf shrimp adults may coexist in a heavily planted aquarium, but Guppies will investigate small moving prey and can eat shrimplets. Snails are usually less vulnerable, although compatibility still depends on water chemistry and the snail species. Never advertise an invertebrate pairing as fry-safe.
| Companion type | Likely fit | Checks before mixing |
|---|---|---|
| Other domestic Guppies | Often suitable | Group size, sex ratio, health, pregnancy risk and available filtration |
| Platies | Often suitable in a larger community | Adult biomass, temperature, hardness and feeding competition |
| Mollies or Swordtails | Conditional | Larger adult size, stronger activity, mineral needs and aquarium volume |
| Small Tetras, Rasboras or Corydoras | Species-dependent | Exact pH, hardness, temperature, group size and feeding behaviour |
| Barbs and known fin nippers | Avoid | Fin damage and chronic chasing risk |
| Large or predatory fish | Avoid | An adult female must not fit in the companion's mouth |
| Dwarf shrimp | Adults may coexist | Shrimplets are potential prey; provide cover and accept losses |

Guppies are livebearers: fertilisation is internal and the female gives birth to free-swimming young rather than laying eggs for external fertilisation. OATA gives a broad example of 20-80 fry after a pregnancy of roughly 24-30 days. Those figures are not a promise for this individual. Brood size and timing vary with age, body size, genetics, temperature, nutrition, stress and reproductive history.
Female Guppies can store sperm after contact with males. Published research has examined prolonged female sperm storage, successive broods and multiple paternity in Poecilia reticulata. The practical customer message is simple: a female may later produce fry even if no male is present after purchase. Pregnancy is possible but neither guaranteed nor excluded.
A developing female may become deeper through the abdomen, and a gravid area near the rear of the body can become more visible. Near birth, some females look more squared from the side and may spend more time around cover. None of these signs gives an exact delivery date, and some can overlap with overfeeding, constipation or illness.
Do not squeeze, net repeatedly or isolate a fish solely because the abdomen looks large. Check that the scales remain flat, swimming is controlled, breathing is steady and the fish still feeds. Raised scales, marked asymmetry, loss of balance or respiratory distress require a health assessment rather than a breeding assumption.
Adult Guppies and other community fish may eat newborn fry. Dense live plants and floating roots increase the chance that some survive in a community aquarium. If the intention is to raise many, prepare a mature separate grow-out aquarium with suitable filtration, heat, cover and appropriately sized food before the birth.
A tiny unfiltered container is not a nursery. Fry increase feeding frequency and waste production quickly, so water quality can deteriorate before the problem is visible. Use a fry-safe mature filter, monitor ammonia and nitrite, and change water carefully without causing sudden temperature or chemistry shifts.
A suitably large breeding net may be used briefly under OATA guidance, but prolonged confinement in a cramped trap can stress a female. Dense planted cover or a prepared separate aquarium usually gives more control. Remove the adult after birth if the goal is maximum fry survival, and never release unwanted fish into the wild.
Guppies reproduce readily, and one unexpected brood can become several generations if males and females mature together. Decide in advance whether you can house, separate or responsibly rehome offspring. Do not breed simply because the fish can breed.
"Blue Neon" does not guarantee that every offspring will look like the mother. The father's identity may be unknown, stored sperm can be involved and domestic colour inheritance is not a simple copy process. This fish is not sold with a pedigree, parentage record or promise of true-breeding offspring.
Previous contact with a male can matter for later broods. Buy this fish because the aquarium suits an adult female Guppy, not because a particular pregnancy outcome is assumed.
Good prevention starts with mature filtration, suitable minerals, stable temperature, measured feeding and compatible stocking. Guppies are often sold as easy beginner fish, yet they can decline rapidly when moved into very soft water, an uncycled aquarium or a crowded mixed community. "Hardy" should never be used as permission to skip testing.
Observe posture, fins, eyes, skin, gills, abdomen, swimming and appetite every day. Compare changes with the fish's own settled baseline. A healthy-looking female generally holds her fins open, swims with control, breathes steadily and responds to feeding without being unable to stop or rest.
These signs are not a diagnosis. The same outward behaviour can have several causes, and medication chosen from a photograph can make matters worse. Test ammonia, nitrite, nitrate, pH, hardness and temperature first. Check oxygen, recent additions, maintenance changes and aggression. Then seek advice from a competent aquatic specialist or veterinary professional when the cause is uncertain or the fish is deteriorating.
A separate mature quarantine aquarium reduces the chance of introducing disease to an established community and allows close observation without competition. It needs a cycled filter, heater, lid and simple shelter. Bare-bottomed setups can make waste and feeding easier to monitor, but they still require stable water and appropriate cover.
Do not medicate every new fish automatically. Preventive treatment without a reason can expose fish and filter microbes to unnecessary chemicals and may hide the real problem. Observe, test and use a treatment only when it matches a credible diagnosis and the product is safe for the species, aquarium and any invertebrates present.
Never rinse established biological media under untreated chlorinated tap water. During maintenance, gently rinse reusable media in removed aquarium water when needed and avoid replacing every element at once. Keep the filter running and oxygenated; a long power interruption can reduce biological capacity.
Use a regular partial water-change routine based on test results and stocking. OATA strongly recommends a weekly 25% change as a general starting point. The actual schedule may need adjustment, but a large emergency correction every few weeks is not equivalent to consistent maintenance.
A Blue Neon female is a good choice when the keeper values a larger, calmer-bodied female profile and wants to add to an appropriate Guppy group. A male is usually smaller and more intensely coloured, with a gonopodium and often longer fins. The sexes are not interchangeable when planning population growth and courtship.
Endler Guppies are Poecilia wingei, a different accepted species, although domestic trade lines and hybrids can blur visual distinctions. Endler males are typically smaller. Do not relabel a fish as an Endler merely because it is compact or brightly coloured, and do not mix species if maintaining a known genetic line matters.
| Choice | Typical distinction | Planning implication |
|---|---|---|
| Blue Neon Female Guppy | Larger female body, fan-shaped anal fin, variable blue-toned colour | Possible stored sperm and fry; use a suitable female group or mixed ratio |
| Male Guppy | Usually smaller, more intensely coloured and equipped with a gonopodium | Mixed groups need more females than males and enough cover for courtship pressure |
| Endler Guppy | Different species, usually smaller, with distinct domestic and wild-type forms | Check species identity, hybrid risk, adult size and the exact listing sex |
| Assorted female Guppy | Sex is specified but colour is intentionally mixed or random | Choose assorted stock only when a particular Blue Neon direction is not required |
Prepare the aquarium before dispatch. Confirm stable temperature, 0 mg/l ammonia, 0 mg/l nitrite, suitable pH and hardness, and enough capacity for the new biological load. Have a net, clean bucket, water conditioner and test kit ready. Switching the aquarium light off before opening the parcel reduces visual stress.
Read the current delivery and Live Arrival Guarantee page before ordering because eligible areas, dispatch days, evidence requirements and weather decisions can change. The guarantee protects eligible livestock under the published conditions; it does not replace the keeper's responsibility to provide suitable water and prompt receiving care.
Open the outer parcel calmly and inspect the sealed bag. If there is an arrival concern, follow the published evidence process before discarding packaging or opening everything out of sequence. Do not make unsupported assumptions from temporary pale colour alone; look at posture, breathing and responsiveness.
Temperature equalisation is only one part of acclimation. pH and dissolved chemistry can differ even when both waters feel equally warm. Test where practical. The greater the difference, the more carefully the transfer method should be chosen, while avoiding an unnecessarily long stay in opened shipping water.
OATA describes floating the sealed bag for about ten minutes, then introducing small amounts of aquarium water over up to twenty minutes before releasing the fish with as little bag water as possible. That is a general method, not a reason to leave a fish in deteriorating transport water for an extended period. Follow the current instructions supplied with the order and adapt to the measured difference.
Our acclimation timer can organise the stages without turning the process into guesswork. Keep hands and equipment free from soap, aerosols and household chemicals. Never siphon by mouth, and do not pour transport water into the display aquarium when a clean transfer can avoid it.
Leave the lights low and avoid repeated netting or photography. Check breathing and swimming from a distance. Offer only a light meal after the fish is settled and do not keep adding food if it refuses. Test the aquarium after the addition and again if behaviour changes.
For any arrival problem, use the same-day process in the returns and Live Arrival Guarantee terms. The page explains the evidence and contact steps. Do not substitute a product-description sentence for the full current terms.
Guppies are frequently recommended to new keepers because they feed readily and remain small, but a beginner still needs to understand cycling, hard-water suitability and population growth. The beginner tropical fish guide helps compare those responsibilities before purchase.
The live Shopify selector is the source of truth for current price and stock. This description does not hardcode inventory or promise a dispatch date.

We do not claim that every fish is the exact animal photographed, that a female is definitely pregnant or not pregnant, that the blue pattern will be identical, or that a domestic Guppy belongs to a documented wild locality. Clear limits make the listing more useful: customers can decide from real sale-unit, size, water and group information rather than generic promises.
FishBase records a maximum female length of about 6 cm standard length. The tail extends beyond standard length, so the visible total can be greater. The 3-4 cm on this listing is an approximate dispatch band, not adult size.
Use at least 60 litres and about 60 cm of horizontal length for a small female group. Increase the aquarium for a mixed community, larger group, retained fry or more active companions. A mature filter and stable water matter as much as volume.
Plan Guppies as social fish. OATA suggests at least three, while FishBase gives five or more. A single purchase is appropriate when adding to an existing compatible group; it should not be planned as permanent solitary housing.
OATA publishes 20-28°C. A stable 23-26°C is a practical long-term target for this listing, adjusted only when every tank mate shares the chosen setting. Avoid sudden fluctuations and monitor oxygen during hot weather.
Aim for pH 7.0-8.0, around 8-18 dGH and 5-15 dKH. Test the actual source and aquarium water. Do not make rapid chemical adjustments or add mineral products without measuring the need.
This product is selected and sold as female. A mature female has a broad fan-shaped anal fin rather than a male gonopodium. Exact maturity and reproductive history are not guaranteed, and colour or body fullness alone should not be used to sex a young fish.
No. The supplier measurement is an approximate dispatch band. Individual length, fin extension and body depth vary, and the fish can continue growing after arrival. Plan around the adult female size.
No. Blue Neon is a domestic trade colour direction. Hue, coverage and intensity vary with genetics, age, lighting, background and settlement. The representative image is not an exact-fish guarantee.
Yes, it is possible. Female Guppies can store sperm after previous contact with males and may produce later broods. This listing does not guarantee or exclude pregnancy, and it does not identify the father of any fry.
OATA says Guppies can live several years in a mature setup with good water quality. There is no honest exact lifespan for an individual because age at purchase, genetics, reproductive history, temperature, diet and husbandry all affect it.
Use an appropriately sized quality flake or micro-granule with plant or algae content, supported by modest portions of suitable frozen or live foods such as daphnia, cyclops or brine shrimp. Feed measured amounts and remove leftovers.
It is not a dependable default pairing. A Betta may chase a Guppy because of its fins or colour, while active Guppies can stress a slower long-finned Betta. Temperament, tank size, cover and water compatibility must all be assessed, with separation available.
Adult dwarf shrimp may coexist in a well-planted aquarium, but shrimplets can be eaten. Guppies are active omnivores and will investigate small moving prey. Do not choose the pairing if every baby shrimp must survive.
No. The preserved product-specific image is representative. It shows a female Guppy profile and the expected blue fin direction, but it does not identify the exact individual, measurement, maturity, pregnancy status or shade dispatched.

This listing combines supplier identity and size information with recognised species, trade and welfare sources. The practical recommendations are intentionally narrower than some biological limits because a stable home aquarium should not be run permanently at an extreme tolerance.
