Assorted Platy (Xiphophorus maculatus)

Assorted Platy is the supplier's mixed-colour listing for the common or southern platy, Xiphophorus maculatus. It is a compact platy fish and livebearer that stays visible in the middle and upper parts of a community aquarium, grazes between feeds and is generally measured with fish of a similar size. Its accessible reputation is deserved only when the aquarium is already cycled and its water suits a mineral-tolerant livebearer; "easy" does not mean suitable for an unfiltered bowl or a new tank with unstable ammonia.

This listing supplies one unsexed fish per selected quantity. "Assorted" means the supplier sends this stock as a mixture rather than a named colour strain. It does not promise that one order will contain several colours, that a particular red, yellow, orange, wagtail or tuxedo pattern will be available, or that the fish will be male or female. Select the required dispatch-size option beside the basket control and increase the Shopify quantity for each additional fish.

The four current gallery images are illustrative views, not photographs of the exact animal that will be packed. They show possible platy-like colour and body presentation, while the dispatched fish can differ in colour, pattern, body depth, fin shape and sex. An image containing two fish does not turn quantity one into a pair. Customers who need a specific named appearance should compare the separately listed strains in our platy collection.

What exactly will I receive?

One selected quantity buys one Assorted Platy. The active Shopify product combines several supplier size codes as choices on one page, but none of those codes is a customer pack quantity. The price, stock and selectable options shown beside the basket are the current commercial record; this care text does not override them.

If several fish are required, choose the available size and set the basket quantity accordingly. Mixed-sex groups can reproduce and male attention can be persistent, so buying a number first and planning the social structure later is not responsible stocking. Read the grouping and breeding sections before choosing a quantity.

Eligible live-fish orders are covered by our current Live Arrival Guarantee; postcode, dispatch and claim conditions are set out on the delivery page. Eligible first-time customers can use WELCOME10 for 10% off under the current checkout terms. Neither offer changes the welfare checks needed before ordering a live animal.

Name, taxonomy and natural range

The accepted species name is Xiphophorus maculatus. The word "mixture" in the supplier record describes the assortment and is not part of the scientific name. GBIF also records Platypoecilus maculatus as the original name usage, which is why older books or databases may use a different genus for the same species.

FishBase and the US Geological Survey place the native range on the Atlantic slope of Middle America, from the Veracruz area of Mexico towards northern Belize. FishBase describes warm springs, canals, ditches, creeks and swamps, often with slow water, silt and vegetated margins. These habitat notes support a planted aquarium with calm areas and open swimming room; they do not mean ornamental assortment stock is wild caught. OATA notes that most platies in the aquarium trade are captive bred, but the exact production country or lineage of this supplier batch is not stated.

What does assorted mean?

Assorted is a stock-management description, not a named breed. It allows different ornamental appearances to be supplied under one species listing when the exact incoming colour mix can vary. A customer may receive a bright solid colour, darker fin contrast, a multicolour pattern or a subtler fish, but no individual appearance should be promised before the fish is selected and packed.

This distinction protects both search accuracy and customer expectations. Terms such as red wagtail, sunset, Mickey Mouse and tuxedo describe separately recognised trade appearances, and they should not be inserted into this product merely because one of those colours is possible. For a defined appearance, compare the Red Tuxedo Platy, Sunset Platy or Mickey Mouse Platy.

Adult size, body shape and gallery limits

Wild-type X. maculatus is a compact, deep-bodied fish without the lower tail extension associated with a male swordtail. FishBase and USGS report males to about 4 cm total length and females to about 6 cm. Ornamental breeding can alter colour, fin presentation and body depth, so a dispatch measurement and an adult maximum are different pieces of information.

The supplier's grown-size figure is approximately 6 cm, consistent with the female maximum in those species references. A 2 cm juvenile should not be expected to look as deep-bodied or fully coloured as a mature fish. Conversely, the XL label is not an exact measurement and must not be translated into a made-up centimetre promise.

The gallery image does not turn an illustrative orange or yellow fish into a stock guarantee. It does not turn an illustrative orange or yellow fish into a stock guarantee. The gallery remains useful for recognising the broad platy form, while this text supplies the necessary commercial boundary.

Is an Assorted Platy right for my aquarium?

An Assorted Platy can suit a first community aquarium when the keeper has completed the preparation: a mature biological filter, suitable source-water chemistry, enough swimming space and a plan for group composition. Platies are active feeders and visible fish, which makes appetite, breathing and social behaviour relatively easy to observe. They are less suitable where the aquarium is soft and acidic, recently set up, overcrowded or shared with fish that chase or outcompete them.

Tank size and stocking space

OATA recommends at least 45 litres for a small group of platies, while FishBase gives a minimum aquarium length of 60 cm. Litres and length answer different questions: water volume helps buffer temperature and waste, while length provides swimming room and space to move away from courtship or competition. For this listing, 60 litres with a 60 cm length is the cautious planning baseline for a small group, with more space required as the group or community grows.

Do not use that baseline as an automatic stocking formula. Filtration capacity, adult biomass, sex ratio, existing fish, plant density and maintenance routine all matter. A 60-litre aquarium already holding a full community may have no responsible capacity for another group. OATA also warns that adding fish too quickly can exceed the established bacterial population and contribute to new tank syndrome.

A secure cover is sensible around any active aquarium fish, but the tank must still exchange gas freely. Leave clear swimming lanes and avoid filling every centimetre with ornament. The care planner can help organise the setup, but direct water tests and observed behaviour remain the final checks.

Aquarium layout, plants and filtration

Use a dependable filter sized for the aquarium and its total stock. The aim is steady biological processing and oxygenation, not a current so strong that fish spend the day fighting the flow. Position the outlet so there are both moving and calmer zones, then confirm that waste is not collecting unseen behind decor.

Live plants are useful for visual cover, grazing surfaces and refuge for fry, although they do not replace water changes or filtration. Hardy stems, floating cover and broad-leaved plants can all work if their light and water needs match the aquarium. If live planting is not practical, smooth artificial plants and aquarium-safe decor can create line-of-sight breaks. Keep some open middle-level swimming space.

Choose sand or smooth gravel according to the whole community rather than the platy alone. Avoid sharp decorations and check every opening against the adult body size. A dark background can make fish easier to observe, but colour display depends on genetics, maturity, health, lighting and surroundings; it is not evidence that a particular assortment colour was promised.

Water parameters with source context

The exact supplier record for this assortment gives 20-25 C, pH 7-8 and 5-30 dGH. FishBase gives 18-25 C, pH 7-8 and 9-19 dH for the species. OATA's broader platy care sheet gives 17-27 C, pH 7-8 and 4-12 dGH. Those ranges overlap but are not identical because one describes this trade record, one summarises species data and one is retail husbandry guidance for platies generally.

Use the supplier range as the stock-specific planning reference, then compare it with the aquarium's measured temperature, pH, GH and KH. The wide supplier hardness range is not permission to move a fish abruptly between very different water. Stability and gradual acclimation matter, and pH should not be forced with quick chemical corrections while alkalinity and source water remain unknown.

There is no single "UK tap water" specification. Water can be soft in one postcode and hard in another, and treatment or private supplies add more variation. Test rather than assume. Our water matcher and water chemistry guide explain the measurements, but a current liquid or calibrated digital test of the actual aquarium is more useful than a regional stereotype.

Cycling, water quality and routine maintenance

Ammonia and nitrite should remain at zero. A platy's reputation for resilience does not make either compound safe. Before purchase, confirm that the filter is cycled and can support additional biomass. The nitrogen-cycle guide explains why clear water can still be chemically unsafe.

OATA recommends regular testing and a weekly partial water change, with 25% given as a general routine. Treat replacement tap water for chlorine or chloramine and match temperature closely enough to avoid a rapid swing. The actual change volume should respond to tests, stocking, feeding and source-water nitrate rather than being copied without context.

Rinse reusable filter media gently in removed aquarium water when maintenance is needed, not under untreated chlorinated tap water. Do not replace every biological medium at once. Record unusual changes in appetite, respiration or behaviour alongside test results; the pattern is often more informative than memory.

What should an Assorted Platy eat?

FishBase records worms, crustaceans, insects and plant matter in the natural diet. OATA recommends a good-quality flake or granule with a meaningful algae component, supplemented with suitably small live or frozen foods. In the aquarium, use an appropriate complete food as the staple and add variety rather than relying on one ingredient or treating algae grazing as a complete diet.

Offer portions the fish can actually finish while you watch. OATA's once-daily guidance is a useful default, but food density, temperature, fish age and community competition affect the appropriate amount. If feeding is divided, reduce each portion rather than doubling the daily ration. Remove persistent leftovers because decomposing food adds to the filter's load.

In a mixed aquarium, confirm that slower or bottom-dwelling fish receive their own suitable food. A platy eating enthusiastically at the surface does not prove every tank mate has fed. Appetite loss, repeated spitting, a hollow appearance or inability to compete should trigger water tests and closer observation, not automatically a larger portion.

Group size, sex and social behaviour

OATA recommends at least three platies and advises two females per male to reduce pressure on females. Treat that as a social-planning principle, not a guarantee that every trio will be calm. Individual behaviour, aquarium footprint, cover and the presence of fry all change the dynamics. More fish require more volume and filtration.

Mature males have a modified anal fin called a gonopodium; females have a more triangular or fan-shaped anal fin and are often larger-bodied. Young fish can be difficult to sex confidently, and this listing does not offer sex selection. A customer ordering several fish may receive an unknown ratio.

An all-male group avoids fry but does not automatically remove social friction, while an all-female group cannot guarantee no young because previously mated females may retain reproductive capacity. Since sex is not selectable here, contact support before ordering if a particular management plan depends on sex.

Choosing tank mates

Platies are generally peaceful, but compatibility is a comparison between exact species and a real aquarium, not a reusable list of common names. Suitable companions must overlap in temperature, pH and hardness, be too large to swallow, have compatible activity and feeding styles, and still leave enough room for each species' own group needs.

Some guppies, mollies, swordtails, small peaceful fish and suitable bottom dwellers can work in correctly sized hard-water communities, but the common name alone is insufficient. Many tetras and Corydoras come from softer water than platies; some individual species overlap, others do not. Use the tank-mate tool as a starting comparison and verify the exact species independently.

Avoid large predatory fish, persistently aggressive species, cramped fin-nipping groups and any setup where a platy cannot feed or rest. Separate fish if there is sustained chasing, damaged fins, blocked access to food or hiding that does not resolve after normal settling.

Livebearing, pregnancy and fry

Platies are livebearers: embryos develop within the female and live young are released. OATA notes that reproduction is likely in mixed-sex groups and gives a general pregnancy range of 24-30 days, but that is not a delivery schedule or a promise that an individual fish is pregnant. Age, temperature, condition, prior mating and stress all affect what a keeper observes.

Dense planting can give fry places to avoid adults and tank mates, but it does not guarantee survival. A breeding plan should cover space, suitable fry food, water quality, separation where genuinely necessary and responsible future homes. Do not crowd adults into a small trap for extended periods merely to maximise fry numbers.

This assorted listing is not sold as breeding stock, a sexed trio or a defined strain. Crossing unknown assortment fish may produce varied offspring, and colour inheritance should not be predicted from the gallery. Customers seeking a named appearance should begin with accurately identified stock and still expect biological variation.

Daily health observations

A healthy settled platy should have clear eyes, intact fins and scales, steady breathing, controlled swimming and an appropriate interest in food. No single sign proves health, and transported fish may be quieter at first. Compare behaviour over time and test water before reaching for medication.

Quarantine new livestock where a suitable, cycled system and competent care are available. Avoid mixing bag water into the display aquarium. If several fish are affected, mortality occurs or signs worsen, seek advice from an aquatic veterinary professional or another appropriately competent fish-health source rather than combining treatments blindly.

Delivery and acclimation

Prepare before dispatch: confirm the aquarium is cycled, test its water, check the heater and filter, and make sure no new tank mate has been added impulsively. On arrival, inspect the unopened bag promptly and follow the instructions linked to the order. Photograph any delivery concern immediately because time-stamped evidence may be required under the Live Arrival Guarantee.

Reduce bright light and avoid sudden temperature or chemistry changes. Our fish acclimation guide explains the sequence. Acclimation cannot make fundamentally incompatible water safe, so compare pH, GH and temperature before purchase rather than trying to solve a large mismatch while the fish is in the bag.

After release, allow quiet settling time and observe breathing, balance and social pressure. Offer only a small appropriate feed once the fish is settled enough to respond; do not use heavy feeding as a health test. Recheck ammonia and nitrite after adding livestock because the filter is responding to a larger biological load.

Responsible long-term ownership

GOV.UK guidance requires fish buyers to receive information about environmental conditions and water quality, but responsible ownership continues after the sale. Plan for the animal's full life, routine costs, holiday care and the possibility of offspring. OATA describes platies as living for several years in a mature, well-maintained aquarium; no exact lifespan can be guaranteed for an individual whose age, genetics and health history vary.

Never release an aquarium fish, fry, plants or aquarium water into the wild. X. maculatus has established non-native populations in multiple countries, and release can harm the fish, native wildlife and biosecurity. If the aquarium can no longer be maintained, arrange a responsible rehome through a suitable retailer, aquarist network or rescue contact.

Compare other platy choices

Choose this assortment when species and size matter more than a specific appearance. Choose a named strain when colour or pattern is central to the purchase, while remembering that living fish still vary. The Red Tuxedo Platy, Sunset Platy and Mickey Mouse Platy are separate X. maculatus listings.

The Assorted Variatus Platy is listed as Xiphophorus variatus, not this species. The shared word "platy" does not make the two listings taxonomically interchangeable, and their exact supplier ranges should be checked separately.

Assorted Platy questions

How many fish does one quantity buy?

One quantity buys one unsexed Assorted Platy in the selected available size. It is not a pack, pair or trio.

Can I choose the colour or pattern?

No. This is a supplier assortment, so exact colour and pattern are not selectable or guaranteed. Choose a separately named strain if appearance is the main requirement.

Can I choose a male or female?

No sex choice is stated for the active options. Juveniles can also be difficult to sex confidently.

Why are several sizes on one product page?

Shopify combines five supplier size grades: 1-2 cm, 2-2.5 cm, 3-4 cm, 5-6 cm and XL. Availability and price are shown live beside the basket.

What does XL mean?

XL is a relative supplier grade. The supplier has not supplied an exact centimetre range, so this page does not invent one.

How large does Xiphophorus maculatus grow?

FishBase and USGS report males to about 4 cm total length and females to about 6 cm. The supplier gives approximately 6 cm as the grown-size reference.

What tank size should I plan?

OATA gives at least 45 litres for a small platy group and FishBase gives a 60 cm minimum aquarium length. We use 60 litres and 60 cm as a cautious planning baseline, with more space for larger groups or communities.

What temperature should I use?

The exact supplier range is 20-25 C. FishBase gives 18-25 C and OATA gives 17-27 C in broader contexts. Keep the aquarium stable and compare the fish's holding conditions before making a gradual transition.

What pH and hardness do platies need?

The supplier gives pH 7-8 and 5-30 dGH. FishBase gives pH 7-8 and 9-19 dH. Test the actual aquarium and avoid rapid chemical correction.

Do platies suit all UK tap water?

No. UK tap water varies substantially by source and postcode. Measure pH, GH and KH rather than assuming local water is suitable.

Are Assorted Platies beginner fish?

They can suit a prepared beginner with a fully cycled, filtered aquarium and suitable water. They are not a shortcut through cycling or water testing.

Should platies be kept in a group?

OATA recommends at least three and advises two females per male in mixed-sex groups. More fish require more space, and this unsexed listing cannot promise a ratio.

Can platies live with guppies, mollies or swordtails?

Some combinations can work where exact species, adult size, group needs and water chemistry overlap. Check each fish rather than relying on the livebearer label alone.

Can platies live with tetras or Corydoras?

Some exact species may overlap, while many prefer softer water than platies. Compare temperature, pH, hardness, group size and feeding behaviour before combining them.

What should I feed an Assorted Platy?

Use an appropriately sized complete flake or granule with suitable plant ingredients, plus occasional small frozen or live foods for variety. Feed observed portions and remove leftovers.

Will mixed-sex platies breed?

Breeding is likely. A female may also have mated before purchase. Plan for fry, adult social pressure and responsible future homes before ordering a group.

How long do platies live?

OATA says several years in a mature setup with good water quality. This page does not promise one fixed lifespan because age, genetics, health, temperature and husbandry vary.

Are the gallery images the fish I will receive?

No. They are representative illustrations. The exact fish can differ in colour, pattern, sex, proportions and size within the selected dispatch grade.

Does the Live Arrival Guarantee apply?

Eligible livestock orders are covered under the current terms. Check the delivery page before ordering because postcode, dispatch and evidence requirements can apply.
