Bumblebee Male Guppy (Poecilia reticulata)

Understand what this male guppy offer includes

The Bumblebee Male Guppy is a selected domestic colour form of Poecilia reticulata, the familiar guppy and a member of the livebearer family Poeciliidae. FishBase records its native distribution across Venezuela, Barbados, Trinidad, northern Brazil and the Guyanas, and gives a maximum of 5 cm standard length for male or unsexed fish. It suits a prepared beginner who can provide a mature biological filter, tested mineral-bearing water, a deliberate social plan and enough horizontal swimming room.

Bumblebee is a trade-form description rather than a separate species, so its fundamental space, water, feeding and social requirements are those of Poecilia reticulata. Eschmeyer’s Catalog of Fishes accepts the name Poecilia reticulata. Domestic colour and fin labels do not guarantee a pedigree, temperament, lifespan or future breeding result.

Decide whether the plan fits

What one purchase means

One purchase supplies one animal.

Sex is guaranteed only when the exact product or selected option explicitly states male or female. This Bumblebee Male Guppy listing is sold as male.

The gallery images are representative of this type of animal rather than photographs of the exact animal supplied, so colours can look slightly different from the live animal.

Use the guppy collection when comparing other guppy forms, but plan each purchase from the product’s stated sex and sale unit rather than from a collection photograph.

Plan around adult size and social needs

Plan adult space from the recorded maximum. FishBase records a maximum of 5 cm standard length for male or unsexed Poecilia reticulata. Standard length excludes the tail fin, and domestic finnage varies, so leave room for the complete fish rather than treating 5 cm as its total tip-to-tip length.

Seriously Fish recommends a base of 45 × 30 cm and about 41 litres for this species. OATA gives at least 45 litres for a small group of smaller livebearers, while our more conservative Guppy Care Guide screens for a mature, filtered aquarium at least 60 cm long and a group of five or more where the sex plan, filtration, test results and other livestock allow.

Use the 60 cm length as the first pass, not permission to fill the aquarium to a calculated maximum. The usable footprint, existing animals, adult body and fin size, filter capacity, observed behaviour and possible fry all affect how many guppies the aquarium can support.

Use these planning values

OATA’s guppy-and-molly guidance gives pH 7–8, 8–18 dGH and at least three fish for the group; these are group values rather than a species-specific optimum. Our routine display range is 22–28°C, and our social policy uses five or more when the aquarium and sex plan pass the wider checks.

A conventional 60-litre aquarium can be a candidate for five guppies only when it is about 60 cm long, mature, filtered, suitably furnished and not already committed to incompatible livestock. Five is a conservative starting group under our policy, not an automatic maximum. A mixed-sex group, fry, weak filtration or persistent chasing can make the same nominal volume unsuitable.

Prepare the aquarium before the fish arrives

Start with a fully functioning biological filter and prove its performance through water tests before adding the fish. The RSPCA explains that biological filtration converts toxic ammonia to nitrite and then to the safer nitrate. Both ammonia and nitrite should read zero before livestock enters the aquarium.

Elapsed time alone cannot tell you whether the filter can process waste. Use repeated tests, then add livestock gradually so the bacterial population can adjust to increased feeding and waste. If you are preparing your first aquarium, follow our first tropical tank preparation guide before arranging the fish’s arrival.

Pass the setup check

A heater is appropriate where the room cannot keep the aquarium within 22–28°C. Choose thermostatically controlled aquarium equipment and check the water itself; neither room temperature nor the heater dial confirms the actual aquarium temperature.

Plan around the water displaced by substrate, decorations and the air gap above the waterline. Nominal litres are useful for choosing equipment and calculating treatments under professional direction, but they do not replace the 60 cm length, adult-size, group, filtration and compatibility checks.

Do not use this fish to mature a new filter. If ammonia or nitrite is detectable before arrival, postpone adding livestock and correct the biological filtration process. A bright, active guppy still depends on stable water and should never be treated as a test of whether an immature aquarium is ready.

Hold stable mineral-bearing water

Run this aquarium at 22–28°C, pH 7–8 and 8–18 dGH for routine care. Aim for stability within those ranges rather than chasing a single middle number. Test the actual source water and aquarium because UK tap-water chemistry varies by area and can change when water companies blend supplies.

Our water chemistry guide explains what pH, hardness, ammonia, nitrite and nitrate mean. Once you have measured values, use the water matcher to compare the aquarium with the guppy ranges. A match is a starting screen; livestock, plants and the aquarium’s recent test history still matter.

Read the numbers together

OATA advises nitrate should not exceed 20 mg per litre above the normal tap-water level. Compare aquarium nitrate with a fresh sample from the source tap rather than using one isolated aquarium reading without context. Record the results weekly so a trend is visible before fish behaviour changes.

Treat replacement tap water with a conditioner that handles the disinfectants used in your supply. Match changes gradually and avoid abrupt shifts in temperature or chemistry. Check product dosing against the actual water volume and follow its label.

Although FishBase records the species from freshwater and brackish environments, that occurrence is not an instruction to add aquarium salt. Do not add salt, minerals or pH-altering products without a measured purpose and a compatibility check for every fish, invertebrate and plant in the system.

A worked example helps: an aquarium at 25°C, pH 7.5, 12 dGH, zero ammonia and zero nitrite passes the basic water screen. It still needs a mature filter, enough length, a suitable social plan and acceptable nitrate. Water values cannot compensate for crowding or persistent pursuit.

Arrange cover, flow and usable swimming room

Give the group a mixture of open horizontal swimming room and cover. Plants or suitable artificial structure can create sight breaks, but they should not fill the whole footprint or trap one fish in a corner. Watch how the fish use the arrangement and move items if pursuit continues through every refuge.

A planted aquarium can suit guppies well, and floating vegetation may be appreciated. Dense cover can also increase fry survival, so planting has a population consequence in a mixed-sex aquarium. Choose the density deliberately rather than assuming more cover is always better.

Build the layout around behaviour

Avoid strong currents that make a long-finned male struggle continuously. Filtration must still circulate and oxygenate the water, so redirect or diffuse an excessive outlet rather than reducing filtration below the aquarium’s needs. Observe swimming across the complete tank: repeatedly being pushed to one end is a reason to change the flow.

Use aquarium-safe gravel or sand and keep waste accessible to a siphon. Decorations should be stable and suitable for long fins, with no sharp edges or narrow openings that could cause injury.

Plants and ornaments do not correct inadequate aquarium length, immature filtration or an unsuitable social group. If one fish hides continuously, misses food, clamps its fins or is repeatedly cornered, reassess the group and layout instead of adding more decoration without observing the result.

Check usable room again whenever new plants grow, ornaments move or another animal is proposed. A 60 cm aquarium can lose much of its practical swimming space when densely furnished, and the remaining footprint must still support the full adult group.

Feed measured portions without fouling the water

Use an appropriately sized, nutritionally complete omnivore flake or granule as the staple. Add safe, compatible algal and invertebrate variety rather than relying on one treat food. Particle size should allow the male and every companion to take food easily without leaving large pieces on the substrate.

Wild guppies are primarily insectivorous according to Seriously Fish, while today’s tank-bred fish accept most aquarium foods. That natural-history point does not require live-collected food.

Use one measured daily feed

Do not keep adding food because the most assertive fish remains at the feeding area. Guppies may continue investigating after an adequate portion, while slower tank mates may need food distributed across more than one point. The useful measure is whether every intended fish feeds and whether food remains to decay.

Overfeeding increases waste and can drive ammonia, nitrite or nitrate upwards. If leftovers appear, remove them, reduce the next portion and test water where deterioration is possible. Do not solve persistent missed feeding by increasing the total amount without first checking competition, particle size and flow.

Fry require food sized for their mouths and especially close water-quality monitoring. If fry appear, reassess population capacity before changing the feeding programme. More frequent nursery feeding belongs in a deliberately prepared nursery with biologically supported filtration, not an improvised uncycled container.

Keep one routine long enough to observe its effect, then make one measured change at a time. A new food, larger portion and new livestock introduced together make it harder to identify why waste, appetite or body condition changed.

Manage arrival and the first month deliberately

Prepare and test the aquarium before the fish arrives. Read our delivery and Live Arrival Guarantee policy before delivery so the receiving, filming and acclimatisation steps are ready.

Follow the arrival procedure in order

1. Be present to receive the parcel so the live fish is not left unattended.
2. Start filming continuously while the parcel is still sealed, then record it being opened and the fish still inside the sealed bag.
3. Float the bag for 20–30 minutes before releasing the fish.
4. Never pour the bag water into the aquarium.

Use staged checkpoints after release

Introduce fish only to companions that have already passed the water, adult-size and behaviour screen. Reduce disturbance while the new arrival settles, but do not dismiss continuing surface gasping, loss of balance, clamped fins, wounds or refusal to feed as normal travel stress.

Quarantine is the safer route when a separate, mature system and dedicated equipment are ready. The MSD Veterinary Manual recommends at least 30 days of isolation, with longer periods where professionally indicated. A quarantine aquarium still needs biologically supported filtration, suitable temperature, cover and repeated water testing.

Do not place a newly arrived fish in a small uncycled container merely to call it quarantine. If a proper isolation system is not ready, do not improvise with conditions that create ammonia or unstable temperature. Keep nets, siphons and other equipment dedicated to the quarantine system to reduce transfer between aquariums.

At the end of the first month, compare the observations with the baseline from arrival. Stable feeding, normal breathing, open undamaged fins and steady swimming are useful signs. Any downward trend should trigger water tests and a review of social pressure, equipment and maintenance.

Maintain the filter and weekly routine

At least once every week, carry out a partial water change of 25%. Adjust the timing if measured waste or the aquarium’s actual load requires an earlier response. Treat replacement tap water with conditioner before it reaches the fish and avoid abrupt temperature or chemistry changes.

Test ammonia, nitrite and nitrate at least weekly and record the results. Include pH and temperature so changes can be compared with behaviour, maintenance and additions. Test immediately rather than waiting for the scheduled day if fish gasp, clamp their fins, stop feeding or swim abnormally.

Follow a repeatable maintenance sequence

1. Record temperature and water-test results before disturbing the aquarium.
2. Inspect the filter outlet and intake for reduced flow or blockage.
3. Siphon accessible solid waste while removing 25% of the water.
4. If the filter needs cleaning, do not run it under the tap.
5. Rinse dirty filter media lightly in aquarium water removed during the partial water change.
6. Condition and temperature-match replacement water, then add it gradually.
7. Recheck equipment, fish behaviour and the security of the cover after maintenance.

Do not replace all biological media at once as a routine task. Follow the filter manufacturer’s safe maintenance directions while preserving established media wherever possible. A sudden loss of bacteria can leave the aquarium unable to process the same amount of waste.

Use reduced flow as a prompt to inspect for blockage, not as a reason to ignore the filter until water quality changes. Conversely, avoid cleaning every component aggressively when only one sponge or intake needs attention. The aim is reliable circulation with an established bacterial population.

Review feeding and stocking whenever nitrate climbs faster than usual or maintenance no longer holds stable results. Larger water changes alone may hide an increasing waste load without addressing overfeeding, fry growth, added livestock or reduced filter performance.

A written log makes small changes visible. Note tests, water-change volume, filter work, feeding changes, new livestock and unusual behaviour. The pattern across several entries is more useful than relying on memory after a problem appears.

Respond early to health and behaviour changes

A settled guppy should swim steadily, breathe regularly, hold open undamaged fins, maintain a normal body profile and feed consistently. Learn the individual’s usual behaviour so a change in swimming, breathing, appetite, colour or social position is recognised quickly.

The RSPCA’s fish health guidance supports a water-quality-led response to concerning changes. Test ammonia, nitrite, nitrate, pH and temperature immediately, then inspect the filter, heater, recent maintenance, food, additions and interactions between fish.

Match the observation to the first action

These signs are warnings rather than diagnoses. Do not choose salt, raised temperature or medication from one symptom. Different problems can look similar, and unnecessary treatment can add stress or expose tank mates to an unsuitable product.

Record the signs with dates, test results and clear photographs where possible. Separate the fish only into a suitable heated, filtered and tested system. If urgent or continuing signs remain, use OATA’s UK fish-vet directory to find qualified diagnostic and treatment support.

Check all inhabitants rather than focusing solely on the most visible male. A shared water-quality problem may affect species differently, while one chased fish may show stress before the rest. The response should address the aquarium cause as well as the affected individual.

Continue recording water values and behaviour after any professionally directed action. Improvement in one sign does not remove the need to confirm stable filtration, normal feeding and safe social behaviour.

Screen every tank mate before mixing

This guppy is peaceful, but no species name guarantees a safe combination. Screen the exact animals, their adult sizes and the complete aquarium rather than relying on a broad community-fish label. Behaviour can change with maturity, group structure, feeding competition and usable space.

Avoid fin-nipping species. Seriously Fish specifically names tiger barbs and serpae tetras as examples, and OATA likewise advises against species that may nip guppy fins. For every other candidate, check whether either animal can swallow or injure the other.

Pass all six compatibility checks

1. Water: choose an overlap within 22–28°C, pH 7–8 and 8–18 dGH rather than holding either animal at the edge of its range.
2. Adult size: compare mature body and mouth size.
3. Behaviour: reject persistent fin-nipping, territorial pressure, cornering or pursuit.
4. Space: include the full social groups and usable footprint required by every species.
5. Feeding: confirm that each animal can reach suitable food without exclusion.
6. Separation: keep a safe response option ready if observed behaviour changes.

A candidate appearing in a peaceful category is not automatic permission to mix it. Corydoras, rasboras, tetras, livebearers and loricariids contain animals with different adult needs. Check the exact species rather than transferring one result to the whole group.

For a stocking and compatibility assessment, send us the aquarium dimensions, measured water values, filter, established livestock, intended group sizes and sex plan. Honest uncertainty remains until the actual animals are observed together, so monitor feeding, fins, breathing, hiding and pursuit after every addition.

Plan the group, sex mix and possible fry

Guppies are social livebearers. OATA advises at least three, while our conservative house policy uses five or more where aquarium capacity and the sex plan allow. This male should therefore be included in a deliberate group plan rather than treated as a permanently solitary ornament.

A male-only group avoids new mixed-sex mating, but it does not remove display, pursuit or feeding competition. Watch whether every male can feed and move out of another fish’s line of sight. Persistent chasing, cornering, hiding or fin damage requires intervention rather than another fish added automatically.

Choose the group before adding fish

For mixed groups, OATA suggests two females to each male to reduce pressure on females and other inhabitants. Treat that as a planning ratio rather than a guarantee. Space, sight breaks and individual behaviour still decide whether pursuit remains manageable.

Guppies give birth to live young, and a female that encountered a male previously may later produce fry. Before mixing sexes, decide how young fish would be housed, fed and responsibly rehomed. Do not rely on adults or tank mates eating fry as population control, and do not move a female into an uncycled container.

Dense planting may help more fry survive, which increases the need for filtration, testing and space. If breeding is not the aim, a male-only plan avoids new mixed-sex mating while still requiring the full social and behavioural checks.

Keep guppies and Endler’s livebearers distinct

Endler’s livebearer is not simply a smaller guppy variety. The formal description of Poecilia wingei establishes it as a distinct species, and Eschmeyer’s Catalog of Fishes lists Poecilia wingei as valid. Keep documented lines apart, and never present mixed descendants as pure representatives of either species.

Reassess the plan whenever fry appear, a fish matures, fins become damaged or feeding access changes. A group that fitted when small may create a different waste and social load later.

Answer the practical questions before ordering

How big does a Bumblebee Male Guppy get?

FishBase records up to 5 cm standard length for male or unsexed Poecilia reticulata, excluding the tail fin. Plan adult space around the complete fish because domestic finnage varies.

What size aquarium does a Bumblebee Male Guppy need?

Use a mature, filtered aquarium at least 60 cm long under Tropical Fish Co’s conservative house guidance. Seriously Fish gives a 45 × 30 cm base and about 41 litres, but dimensions, filtration, livestock and test results must all pass the complete screen.

How many Bumblebee Male Guppies should I keep together?

FishBase recommends keeping Poecilia reticulata in groups of five or more. Tropical Fish Co uses five or more where aquarium capacity, filtration, other livestock and the sex plan allow.

Is a Bumblebee Male Guppy suitable for a beginner?

It can suit a prepared beginner under Tropical Fish Co’s easy care assessment, provided the aquarium is mature and filtered, ammonia and nitrite are zero, the water is tested and the social group is planned.

What does a Bumblebee Male Guppy eat?

Feed an appropriately sized, complete omnivore flake or granule as the staple, with safe compatible algal and invertebrate variety. OATA’s guppy-and-molly guidance advises only what the group consumes within a few minutes once a day.

What temperature, pH and hardness does this fish need?

Use Tropical Fish Co’s routine temperature of 22–28°C. OATA’s guppy-and-molly group guidance gives pH 7–8 and 8–18 dGH, with zero ammonia and zero nitrite.

Is this fish aggressive or likely to nip fins?

Seriously Fish describes Poecilia reticulata as very peaceful. Monitor display, pursuit and feeding access within the guppy group, and avoid fin-nipping tank mates such as tiger barbs and serpae tetras.

Which kinds of animals can it live with?

Seriously Fish names other livebearers, rasboras, corydoras, small loricariids and tetras for a quiet community, but screen the exact species for overlapping water, adult size, group needs, feeding and usable space. Avoid tiger barbs, serpae tetras and other fin-nipping species.

How does this fish arrive alive in the UK?

Start filming continuously while the parcel is still sealed, then record it being opened and the fish still inside the sealed bag. Be present to receive the parcel, float the bag for 20–30 minutes before releasing the fish, and never pour the bag water into the aquarium.
