Pineapple Swordtail (Xiphophorus hellerii)

What You Receive

One fish per quantity

Each basket unit is one live Pineapple Swordtail. The product has two size options, not a wholesale pack. Select the available size that fits the intended group and aquarium. The current product options do not offer male, female, pair or trio selection.

Option detail	Current meaning	Not promised
4-5 cm option	One fish at approximately 4-5 cm	Not an exact measured length
6-8 cm option	One fish at approximately 6-8 cm	Not an adult-size guarantee
Quantity 1	One live fish in the chosen size	Not a pair or pack of ten
Sex	Unsexed	No male or female guarantee
Colour	Pineapple trade variety	No identical pattern promise
Gallery	One representative illustration	Not an exact-stock photograph

Availability belongs to each variant

The size selector shows which option can currently be ordered. One size may be available while the other is out of stock. This description does not hardcode quantities because inventory changes; the live variant state at checkout is the commercial source of truth.

Size is approximate

Fish are living animals rather than machined parts. The selected size band is a practical guide and normal variation is possible. A 6-8 cm fish is not necessarily mature, sexable or finished growing, while a 4-5 cm fish still needs the complete adult aquarium from the outset.

Species Identity and Correct Spelling

The accepted name

The accepted scientific identity is Xiphophorus hellerii, a member of family Poeciliidae and order Cyprinodontiformes. NCBI Taxonomy records X. hellerii as the current name and the single-i form X. helleri as a synonym.

Why the old spelling remains in the URL

The product URL and existing category architecture contain historic spellings. They remain unchanged to avoid breaking a crawled address and internal navigation. The customer title, care data and principal copy use the accepted double-i spelling; the old path does not describe a different animal.

Name or term	Role	Customer consequence
Pineapple Swordtail	Commercial colour-variety name	General warm colour identity; exact markings vary
Xiphophorus hellerii	Accepted species name	Used for taxonomy and care evidence
Xiphophorus helleri	Recorded synonym and old trade spelling	May remain in paths and older literature
Green swordtail	Species common name	Natural species context, not a colour promise
Platy	Related Xiphophorus fish	Not the species offered on this page

Swordtail, not platy

Platies and swordtails are close relatives and can hybridise in aquaria, which helps explain confused retail naming. This product is sold as X. hellerii, the swordtail species. The stale word platy in the preserved URL is not a second product identity.

Understanding the Gallery Image

A representative generated illustration

The sole gallery image was generated as a visual guide because the current source record has no reference photograph. It shows an orange, male-like swordtail in a planted aquarium. It is not a photograph of the exact fish that will be dispatched.

The image does not select sex

An adult male swordtail can develop the lower caudal-fin extension that gives the group its name. Females usually lack that male sword and may grow larger. Because this product has no sex option, receiving a fish without a sword does not mean that the wrong species was supplied.

Colour develops under real conditions

Age, genetics, diet, social state, background and lighting all influence visible colour. A newly transported fish may look paler while settling. Use the image to understand the broad Pineapple theme, not as a calibrated colour sample or a promise of one precise red-orange boundary.

Published record and retail recommendation

FishBase records 22-28°C, pH 7.0-8.0, 9-19 dH, adult females to 16 cm and an 80 cm aquarium minimum. The 120-litre recommendation adds practical water volume and social headroom for five fish; it is not a claim that FishBase specifies exactly 120 litres.

Measure the destination aquarium

Check internal swimming length, not only the volume printed on packaging. Substrate, hardscape and equipment reduce usable space. Measure pH and general hardness as well; a regional reputation for hard water is not a substitute for testing the actual supply.

Is This Swordtail Right for Your Aquarium?

A good match when

This variety suits a mature neutral-to-alkaline aquarium with mineral-rich water, at least 80 cm of horizontal room, a planned swordtail group and peaceful companions that can keep pace at feeding time. It rewards a keeper who enjoys active livebearer behaviour and accepts variation in sex and colour.

Choose another fish when

Choose another species for a 60-litre community, very soft acidic water, an open-top aquarium, a single-fish plan or a setup already crowded with fast midwater fish. This product is also unsuitable when a guaranteed male sword, female group, breeding pair or exact photograph match is required.

Existing setup	Fit	Reason
Mature 120L+ hard-water community	Potentially suitable	Confirm length, group and companions
Dedicated swordtail group	Potentially suitable	Manage males, cover and reproduction
60L aquarium	Unsuitable for five adults	Too little adult swimming and social room
Soft acidic blackwater aquarium	Poor fit	Mineral chemistry does not match
Open-top display	Unsuitable	Active swordtails can jump
Guaranteed male display	Not supported	Sex is not selectable

Why care is moderate

Swordtails accept prepared foods and can be robust, but that does not make every setup suitable. Adult length, male rivalry, courtship, fast reproduction, jumping and hard-water requirements all need planning. A moderate label is more honest than presenting this as a small effortless platy.

Aquarium Size and Group Footprint

Practical minimum for five

Use at least 120 litres with 80 cm or more aquarium length for five swordtails. A longer aquarium is preferable where more than one male may develop, tank mates share the middle water, or the keeper expects offspring. The supplied fish may look small, but the adult setup is required from the beginning.

Adult dimensions matter

FishBase records up to 14 cm for male or unsexed fish and 16 cm for females. A male's sword adds visual length and requires clear turning room, while a large female carries substantial body mass. Stock using the adult animal rather than the current size option.

Planning case	Direction	Important note
Five adults, species-led setup	120L+, 80 cm length	Use planted barriers and open lanes
More than one mature male	Increase length substantially	Monitor territorial pressure
Swordtails with tank mates	Increase footprint and filtration	Fit every species at adult size
Fry retained in the display	Add planned capacity	Do not let reproduction create crowding
Temporary juvenile tank	Short planned use only	Do not delay the adult home indefinitely

Why a 60-litre claim is not used

Search Console recorded one impression for a query about a 60-litre minimum, but one impression is not husbandry evidence. A group of active fish capable of reaching 16 cm needs more practical space. Search copy should answer the question responsibly, not repeat the smallest number likely to attract a click.

Cycling and Water Quality

Use a biologically mature filter

Add swordtails only after the aquarium can process waste reliably. Ammonia and nitrite must remain at zero. A calendar does not prove cycling; measured processing and stable test results are the evidence. Adding several active livebearers at once can challenge a marginal filter.

Nitrate and partial water changes

Keep nitrate controlled through appropriate stocking, measured feeding, plant growth where useful and regular partial changes. Match replacement-water temperature and mineral content. The correct change volume depends on measured accumulation, not a fixed slogan used for every aquarium.

Oxygen is part of water quality

Warm, crowded water holds less oxygen. Maintain visible surface movement and unobstructed circulation. If several fish breathe rapidly or gather at the surface, test temperature, ammonia and nitrite immediately rather than assuming they are asking for food.

Temperature, pH and Hardness

Parameter	Target	Avoid
Temperature	22-26°C preferred	Rapid change or chronic overheating
Published temperature	22-28°C	Treating the upper edge as an automatic target
pH	7.0-8.0	Persistently acidic water
General hardness	9-19 dGH	Very soft mineral-poor water
Ammonia	0	Any detectable reading
Nitrite	0	Any detectable reading
Nitrate	Low and controlled	A continuously rising trend

Stable chemistry before decimal chasing

Stable pH in a suitable range is more valuable than repeated chemical correction to hit one decimal. If source water is too soft, understand general and carbonate hardness before changing it. Sudden mineral or pH shifts can harm fish even when the final reading looks acceptable.

Routine salt is unnecessary

Do not add aquarium salt by habit. Build suitable freshwater hardness with known mineral chemistry and consider every plant, invertebrate and tank mate. Therapeutic salt should follow a diagnosis and a compatible treatment plan, not serve as a substitute for clean water.

Check before ordering

Use the water parameter matcher with measured temperature, pH and hardness. Confirm ammonia, nitrite and nitrate separately. This is especially useful when the attractive Pineapple colour risks becoming more memorable than the species' actual water requirements.

Aquascape and Swimming Space

Planted margins, open centre

Use robust plants at the sides and rear to break sight lines, then leave a broad horizontal lane for swimming. Floating cover can reduce exposure, but keep part of the surface open for gas exchange. A completely dense layout can restrict a long-bodied adult as much as a bare tank can increase social pressure.

Secure hardscape and lid

Use smooth, stable wood and rock. Check that an adult sword cannot be trapped behind equipment. Cover cable, filter and feeding gaps with a secure lid; active swordtails can jump, particularly when startled or pursued.

Feature	Purpose	Good practice
Dense side planting	Visual refuge	Keep adult turning room
Open horizontal lane	Swimming and display	Use the longest clear dimension
Floating cover	Surface shelter	Retain gas-exchange openings
Smooth wood or stone	Territory breaks	Secure every piece
Tight lid	Reduces escape risk	Close equipment gaps

Lighting and colour

Choose a regular photoperiod that supports plants without forcing the fish into constant glare. Warm body colours can look different under various LEDs and backgrounds. Lighting should reveal a healthy fish, not be used to judge it against a digitally rendered colour sample.

Filtration, Flow and Oxygen

Moderate oxygen-rich movement

Wild species records include flowing streams and rivers as well as canals and ponds. A domestic colour variety benefits from clean, oxygenated water and useful circulation, but it should not be pinned against one powerful outlet. Spread flow and retain calmer planted refuge.

Protect intakes

A sponge pre-filter protects smaller fish and any unexpected fry. Rinse mechanical media in removed aquarium water when flow declines. Protect mature biological media from chlorine and avoid replacing all filter media at the same time.

Plan for equipment failure

During a power cut, oxygen becomes urgent. Reduce feeding, keep media wet and restore surface movement where safely possible. After a long interruption, test ammonia and nitrite because clear-looking water does not prove that the biological filter remained fully functional.

Behaviour and Social Management

Active community fish

Pineapple Swordtails are visible, quick-moving livebearers that commonly use the middle and upper water. They can fit a peaceful community, but their pace and appetite may overwhelm slow delicate companions. Observe access to food and refuge, not only visible fighting.

Observation	Possible meaning	Response
Brief display or chase	Normal social interaction	Confirm that the target can disengage
Repeated male confrontation	Territorial rivalry	Increase space and revise male number
One fish hidden continuously	Social pressure or illness	Check group, cover and water
All fish at the surface	Possible oxygen or toxin problem	Test and aerate immediately
Normal exploration and feeding	Useful positive sign	Continue daily observation

Male rivalry

FishBase specifically notes aggression between males. A small aquarium with two mature males can concentrate conflict. More length, multiple visual barriers and a carefully composed group are more useful than simply adding another fish to distract them.

Courtship pressure

Males may pursue females persistently. When sex is deliberately selected, more females than males can help distribute attention, but this product does not offer sex selection. Be prepared to adjust the group if the eventual composition produces chronic pressure.

Sex and Sword Development

Adult male features

Mature males can develop the extended lower caudal-fin sword and a modified anal fin called a gonopodium. Sword length and development vary. A juvenile without a visible extension may later mature as male, so early appearance is not a firm sex guarantee.

Adult female features

Females retain a broader fan-shaped anal fin, usually lack the male sword and may reach the larger documented body length. Body fullness alone does not prove pregnancy. Feeding, maturation, body shape or illness can alter the abdomen.

Why size does not guarantee sex

The 6-8 cm option can be easier to assess than a smaller juvenile, but size is not a contractual sex option. Stress, variable development and individual growth make remote guarantees inappropriate. Buy the selected size, not an assumed sex.

Livebearing and Reproduction

Fry are possible, not promised

X. hellerii is a livebearer. A mixed-sex group may produce free-swimming fry, but this product does not promise a female, pregnancy, brood size or breeding success. Water quality and adult welfare should not be compromised in pursuit of fry.

Plan capacity before breeding

Fry grow into active adult fish needing space, food and suitable homes. Dense planting may allow more fry to survive, which increases future stocking pressure. Decide how offspring will be housed before retaining them rather than reacting after the aquarium becomes crowded.

Hybridisation risk

Swordtails and platies share genus Xiphophorus and can hybridise. Mixed colour displays may be attractive, but do not sell or distribute undocumented offspring as a pure Pineapple line. A keeper preserving a known strain should use reliable source records and deliberate separation.

Never release unwanted fish

The US Fish and Wildlife Service evidence review records introduced swordtail populations across many regions. Never release adults, fry, plants or aquarium water into ponds, streams or outdoor drains.

Feeding a Pineapple Swordtail

Complete omnivore staple

Use a quality flake, granule or small pellet formulated as a complete omnivore food. Particle size should suit the smaller selected variant while remaining visible to all group members. The complete staple provides consistency that treats alone cannot supply.

Food type	Role	How to use it
Complete flake or granule	Nutritional base	Offer measured portions
Plant-rich or spirulina food	Plant and algal component	Rotate within the balanced diet
Daphnia, cyclops or brine shrimp	Invertebrate variety	Use modest live or frozen portions
Blanched vegetable	Occasional enrichment	Remove uneaten material promptly
Rich worm foods	Occasional supplement	Do not make them the whole diet

Small portions protect water

Swordtails are enthusiastic feeders and may continue approaching the keeper after receiving enough. Feed what the group consumes promptly and remove leftovers. Overfeeding increases waste, nitrate and digestive stress; begging is not a reliable portion guide.

Distribute food

Use more than one feeding point so a dominant fish cannot intercept everything. Confirm that slower tank mates and smaller swordtails eat. Repeated spitting, inability to swallow or progressive weight loss requires investigation rather than simply offering more food.

Tank-Mate Compatibility

Match water and pace

Potential companions must accept 22-26°C, neutral-to-alkaline moderately hard water and the swordtail's active feeding style. The livebearer hub helps compare related fish, while the swordtail category keeps the focus on options with more closely aligned adult behaviour.

Companion type	Guidance	Main check
Other swordtails	Often suitable	Male rivalry, courtship and adult space
Calm hard-water community fish	Potentially suitable	Adult size and feeding speed
Peaceful bottom dwellers	Potentially suitable	Footprint, hardness and food access
Platies or other Xiphophorus	Use caution	Hybridisation and stocking
Slow long-finned fish	Use caution	Activity and feeding competition
Dwarf shrimp or tiny fry	Use caution	Small animals may be eaten
Large predators or fin-nippers	Avoid	Injury and chronic stress

Compatibility is conditional

No list guarantees behaviour. Aquarium length, exact sex composition, cover, feeding access and individual temperament all matter. Keep a safe alternative arrangement available before adding fish to an established group.

Use the exact species category

The Xiphophorus helleri category uses the existing storefront spelling and shows closely related listings. Each product still needs its own size, sex and sale-unit check; related category membership does not make options interchangeable.

Delivery and Acclimation

Prepare the adult home first

Confirm cycling, lid security, water chemistry and adult group capacity before dispatch. Have test kits and suitable food ready. A newly arrived swordtail should not be placed into an improvised uncycled container while the permanent aquarium is still being planned.

Stage	Action	Avoid
Before arrival	Test and prepare the destination tank	Last-minute pH chasing
At delivery	Open promptly and inspect	Leaving the parcel unattended
Acclimation	Follow current supplied instructions	One ritual for every transport condition
Transfer	Move the fish as directed	Pouring transport water into the aquarium
First hours	Keep lighting calm and observe breathing	Immediate heavy feeding

Follow current livestock instructions

Bag chemistry changes after opening, so follow the instructions supplied with the order. The acclimation timer is useful only where that method matches the current instructions. Do not prolong acclimation automatically because a longer process sounds more careful.

Live Arrival Guarantee

Eligible livestock orders are covered under the current guarantee when its reporting and evidence conditions are followed. Read the delivery and guarantee information, choose a suitable delivery day and ensure someone can receive and inspect the parcel promptly.

The First Seven Days

First day

Keep disturbance low and check balance, breathing and ability to shelter. A fish may be pale after transport. Avoid repeated netting, glass tapping or lifting decor to force visibility unless an urgent welfare issue requires intervention.

Days two to three

Offer a small familiar food and confirm that the new fish can reach it. Test ammonia and nitrite, especially after adding several swordtails. Watch male-male display, courtship and whether established residents exclude the newcomer.

Days four to seven

Look for stable feeding, normal swimming, intact fins and improving colour. Continue testing because the biofilter may react after the initial day. Record any concern with dates, water readings and clear images so support or aquatic veterinary advice has useful evidence.

Routine Maintenance

Daily observation

Count the group and compare breathing, posture, body condition, fins, skin, appetite and social position. A fish hidden behind the filter every day is not displaying normal group confidence merely because no injury is visible.

Water changes guided by tests

Use measured nitrate, stocking and feeding to set change frequency and volume. Dechlorinate where required and bring replacement water close to the aquarium's temperature and mineral chemistry. Avoid a routine that creates large weekly swings.

Filter and equipment care

Remove mechanical waste without sterilising biological media. Inspect the lid, heater, intake guard, impeller and hardscape stability. A gradual decline in flow is a maintenance signal, not a reason to increase pump power through a blockage.

Health Observation and Escalation

Useful signs of normal condition

A settled swordtail should hold balance, respond to its surroundings, breathe without visible effort and compete appropriately for food. Colour varies, so body condition and behaviour are more reliable than comparing the fish with one generated image.

Sign	Immediate check	Next step
Rapid breathing	Oxygen, temperature, ammonia and nitrite	Correct environment and seek advice
Clamped fins or isolation	Water and social pressure	Document and investigate
White spots or excess mucus	Whole group and recent additions	Obtain a diagnosis
Weight loss despite feeding	Food access, intake and faeces	Seek specialist assessment
Abdominal swelling	Scales, feeding and behaviour	Do not assume pregnancy
Frayed fins	Rivals, decor and water	Remove the cause and assess damage

Diagnose before medicating

Environmental, infectious, nutritional and social problems can produce similar signs. Test the water first and gather a clear history. Avoid mixing medication, salt and rapid chemistry changes because overlapping interventions can increase harm and hide the original cause.

When to seek help

Seek an aquatic veterinarian or experienced fish-health professional for persistent breathing difficulty, loss of balance, severe injury, progressive swelling, repeated deaths or a problem affecting several fish. Product copy cannot diagnose an individual animal.

Long-Term Care and Lifespan

No fixed lifespan guarantee

Age at purchase, genetics, water quality, temperature, reproduction, nutrition and disease exposure all affect longevity. The current source does not provide age or a guaranteed lifespan. Plan for years of responsible care without turning a commonly searched number into a product promise.

The smaller option still grows

A 4-5 cm swordtail may change substantially in body size, sex characteristics and social behaviour. Do not postpone the adult setup because the fish currently fits a smaller aquarium. The 6-8 cm option also remains below the documented 16 cm maximum.

Temperature and metabolism

Continuous care at the warmest published limit increases metabolic and oxygen demand. A stable 22-26°C target provides useful headroom for ordinary domestic care. Respond to hot weather with ventilation and oxygenation rather than abrupt cold-water additions.

Pineapple Swordtail Compared with Related Fish

Fish or variety	Key distinction	Does this listing promise it?
Pineapple Swordtail	Warm yellow-orange trade variety of X. hellerii	Yes; exact pattern varies
Green Swordtail	Species common name and wild-type context	Species identity, not wild colour
Kohaku Swordtail	Different red-white variety	No
Red Wagtail Swordtail	Different dark-fin variety	No
Platy	Related but smaller Xiphophorus species/forms	No
Guaranteed male	Would require a sex option	No

Pineapple is a colour name

The trade name describes broad warm coloration and does not prove a closed breeder line. Domestic swordtails have complex histories, and appearance alone cannot establish genetic purity. This listing avoids assigning a breeder, generation or locality that the source does not provide.

Swordtail versus platy care

Both are livebearers in family Poeciliidae, but swordtails are longer, more active and capable of a much larger adult size. A setup suitable for a small platy group may not provide enough horizontal room for adult X. hellerii.

Scientific Context

Natural range and habitat

Species records extend from Veracruz in Mexico through parts of Central America to northwestern Honduras. Adults occur around vegetation in fast streams and rivers, as well as springs, canals and ponds. A domestic Pineapple colour variety does not carry a wild collection-location claim.

Diet evidence

FishBase reports worms, crustaceans, insects and plant matter. That supports a varied omnivore diet with both plant and invertebrate components. It does not justify using rich bloodworm as the only food or treating the fish as a dedicated algae cleaner.

Limits of species-level evidence

Scientific sources describe the species, not the exact retail animal. They cannot prove this individual's sex, age, reproductive status, colour, breeder or health history. The live Shopify variant and this explicit sale contract define what the customer can select.

Ordering Responsibly

Select the size, then the quantity

Choose 4-5 cm or 6-8 cm only when that variant is available. Set quantity for the number of fish required. Recheck the full adult stocking plan before checkout; a lower current price or a larger available inventory does not create more aquarium capacity.

First-order offer

New customers can use WELCOME10 for 10% off a first eligible order, subject to the current promotion terms. Complete cycling, water matching and adult-space planning before using a discount.

Price and stock are live

The product controls show current price and availability for each size. This description deliberately avoids hardcoding those values. An item is not reserved until checkout completes successfully.

Pineapple Swordtail FAQ

How many fish are included?

One live fish is included per quantity selected. Choose the available 4-5 cm or 6-8 cm option. It is not a pair or pack of ten.

Is the fish male or female?

Sex is not selectable or guaranteed. The representative image shows a male-like fish, but that does not change the unsexed sale contract.

Will every fish have a sword?

No. Mature males can develop the lower tail extension; females normally do not, and juveniles may not yet show adult sex characteristics.

How large does it grow?

Plan for up to about 16 cm total length, allowing for larger females and the visual length of a male sword. Both selectable sizes may still grow.

What aquarium size is suitable?

For five swordtails, use at least 120 litres and 80 cm length. Increase space for multiple males, more fish, tank mates or retained fry.

Can I keep one Pineapple Swordtail?

A permanent singleton is not recommended. Plan at least five swordtails, with enough length and visual refuge to manage social interaction.

What temperature should I use?

Target 22-26°C for normal long-term care. The published species range extends to 28°C, but the upper edge is not an automatic everyday target.

What pH and hardness are suitable?

Target pH 7.0-8.0 and 9-19 dGH with zero ammonia and nitrite. Very soft acidic water is a poor match.

What should I feed?

Use a complete omnivore staple with plant-rich foods and modest small frozen or live invertebrate variety. Feed measured portions and remove leftovers.

Can it live with platies?

Potentially, where adult space, water and behaviour match, but hybridisation is possible. Do not mix them when preserving a documented line matters.

Is the gallery image the exact fish?

No. It is a representative generated illustration. Exact sex, colour, markings, fin length, maturity and body proportions vary.

Is Xiphophorus helleri a different fish?

No in this listing. X. helleri is a recorded synonym and common old spelling for X. hellerii. The accepted double-i form is used in the customer title.

Final Aquarium Checklist

Before adding to the basket

• The aquarium is cycled, covered and at least 120 litres with 80 cm length for five.
• Measured water is 22-26°C, pH 7.0-8.0 and 9-19 dGH.
• Ammonia and nitrite are zero and nitrate is controlled.
• The adult group, possible male rivalry and possible fry are planned.
• Tank mates match the water, adult size and active feeding pace.
• You understand that size is selectable but sex and exact colour are not.

At arrival

Receive the parcel promptly, follow the current livestock instructions and keep lighting calm. Check breathing and balance before offering a small meal after the fish settles. Document any immediate concern according to the guarantee process.

For long-term success

Maintain stable mineral-rich water, open horizontal room, planted sight breaks, a varied measured diet and a socially workable group. Treat the Pineapple name as a living colour variety and let the actual fish, not a repeated keyword or illustration, define the individual you keep.
