XL Mix Angelfish (Pterophyllum scalare) is one live, larger juvenile domestic freshwater Angelfish per selected quantity. The supplier grade is 6-7 cm. It gives more immediate height and presence than a small juvenile. It is not the adult size.
Mix means the colour and markings vary. A selected fish may be silver, gold, marbled, smoky, dark-barred or another domestic combination available in the batch. The fish is unsexed and is not a bonded or breeding pair. No exact colour is promised. The gallery contains one owner-approved representative image of a plausible silver-striped Angelfish; it is not a WYSIWYG photograph of the animal that will be dispatched.

Quantity one means one living Angelfish. The listing does not include a mate, bonded partner or breeding pair. Sexing immature domestic Angelfish reliably from appearance is difficult, and the supplier has not provided a sex guarantee.
The supplied 6-7 cm grade helps compare this fish with smaller Angelfish listings. It does not describe the final body length, fin height, age or sexual maturity. Prepare the adult aquarium before ordering rather than planning to upgrade after the fish has become territorial.
The shared identity is domestic Pterophyllum scalare, not one named colour strain. The exact body colour, bar strength, marbling, metallic sheen and fin shading depend on the fish selected from the current batch. Variation is part of this product, not a quality fault.

| Eligible UK livestock delivery support | A fish that can live safely with every community species |
Mix is a trade description for assorted domestic forms of Pterophyllum scalare. Selective breeding has produced many colours and patterns while retaining the familiar tall, laterally compressed cichlid shape. Mix should not be written as part of the scientific name or treated as a separate species.
FishBase describes a compressed, disc-shaped body with extended dorsal and anal fins. This profile is central to aquarium planning. An Angelfish needs useful water depth and clear turning space even when its measured nose-to-tail length seems modest.
The species has South American Amazon-basin ancestry, but this product is a domestic ornamental mix. It should not be presented as a wild-collected locality fish or used to predict one exact natural colour pattern.
The existing image is a clear, high-resolution representative illustration of a silver-striped freshwater Angelfish in a planted aquarium. It usefully shows the tall body, long dorsal and anal fins, trailing ventral fins and the kind of vertical swimming space the species needs.
Petra supplied no exact photograph, image ID, source URL or extra image for this product. The gallery image was created for this product under an earlier owner-approved image-recovery policy. It cannot predict the colour, pattern, sex, fin condition, individual proportions or exact fish selected for dispatch.
A photo from another Angelfish product could imply a specific strain that is not included in this mixed listing. Keeping one clearly disclosed representative image is more accurate than borrowing another product's animal or generating additional unverified scenes.
Published species guidance reports total length up to about 15 cm. The supplier record also carries a larger grows-up-to figure without defining whether it includes the full fin profile. For practical planning, allow for a tall adult whose dorsal, anal and ventral fins make the occupied vertical space much greater than body length alone.
For one adult or an already established compatible pair, plan around a mature aquarium of roughly 180 litres, at least 100 cm long and about 50 cm of useful water depth. These dimensions are a responsible starting interpretation, not a guarantee that any two fish will coexist.
A social group needs materially more room. Around 240 litres and 120 cm length is a practical starting baseline for a modest group, with more space preferred. Height, planting, sight breaks and the ability to separate a bullied fish matter as much as the headline litre number.
| Setup | Planning guidance | Main risk to manage |
|---|---|---|
| One Angelfish | Around 180 litres, 100 cm length and useful depth | Compatible community and enough adult turning space |
| Established compatible pair | Around 180 litres or more, with a defended spawning zone | Territorial pressure on other fish |
| Juvenile social group | Around 240 litres and 120 cm length or more | Hierarchy, pair formation and focused bullying |
| Mixed cichlid display | Species-by-species assessment; extra territories required | Overlapping aggression and feeding competition |
| Small or low aquarium | Not suitable | Restricted fins, unstable water and no retreat space |
Their slow movement can look peaceful, but Angelfish form social hierarchies and use displays, chases and defended areas. Individual behaviour changes with age, group composition, space, feeding and breeding condition.
Placing two unrelated Angelfish together can concentrate aggression on one subordinate fish. A true pair forms through behaviour; it cannot be created by ordering two unsexed animals and assuming they will bond.
A compatible pair may defend a broad leaf, root or other vertical surface. Both parents can guard eggs and the surrounding territory. The community must have enough distance and visual cover, and a separate mature home should be available if pressure becomes persistent.
Peer-reviewed ornamental-fish research found group-size effects to be species-specific and Angelfish responses variable. A common starting group is five or more juveniles in a genuinely large aquarium, but space, hierarchy and individual behaviour must still be observed rather than assumed.
Use tall planting, vertical wood and broad leaves around the sides and rear while preserving open middle-water lanes. The fish should be able to turn without folding long fins against hard decor.
Roots and plant groups interrupt constant visual contact between dominant and subordinate fish. They also create a calmer route away from a pair's defended area. Keep every structure stable and smooth enough for long fins.
A mature biological filter is essential, but the fish should not have to swim continuously against a narrow high-speed jet. Spread the return flow, protect strong intakes and retain quieter feeding and resting zones.
Use a secure lid or cover while maintaining normal gas exchange. A startled fish can jump, and a cover also reduces rapid temperature and evaporation changes.
A stable practical range for this domestic line is 24-28 C, pH 6.0-7.8 and approximately 5-13 dH. FishBase reports a broader species temperature range of 24-30 C and pH 6.0-8.0; the tighter retail range gives a useful shared target for normal community planning.
| Measure | Practical target | Decision rule |
|---|---|---|
| Temperature | 24-28 C | Keep steady; match companions to the same warm range |
| pH | 6.0-7.8 | Stability is safer than repeated rapid adjustment |
| General hardness | About 5-13 dH | Acclimate gradually if source and home water differ |
| Ammonia | 0 mg/l | Any detection needs immediate investigation |
| Nitrite | 0 mg/l | Any detection is unsafe |
| Nitrate | Low and stable | Use trends and source-water baseline; avoid accumulation |
Research in social groups of Pterophyllum scalare found that a large abrupt water renewal could temporarily increase aggressive interactions more than a smaller renewal. The useful home-aquarium lesson is to perform regular controlled maintenance with well-matched replacement water. It is not a reason to skip necessary water changes.
Record temperature, pH, ammonia, nitrite and nitrate trends. Also check filter flow, heater operation, uneaten food and dead plant matter. A single acceptable reading cannot prove that a new or overcrowded aquarium is mature.
Use the water matcher to organise measured values before ordering. It supports comparison but does not certify compatibility or aquarium maturity.
Feed a quality tropical cichlid flake, soft granule or appropriately sized pellet as the nutritional foundation. The fish should take pieces comfortably without repeatedly spitting out food that is too large or hard.
Measured frozen or live foods such as Artemia, daphnia, mysis and suitable insect larvae can add variety. Avoid relying on one rich food, and do not use mammal meat as a routine staple.
One or two small feeds daily is a practical home routine, adjusted to body condition, age and the wider community. Peer-reviewed feeding research found two feeds useful in a production context, but aquarium portions must remain small enough to be eaten promptly.
Dominant fish may control the easiest feeding position. Spread food across more than one area and confirm that quieter individuals eat. A fish that hangs back, darkens, clamps its fins or loses condition may be experiencing social pressure rather than simple fussiness.
Suitably sized peaceful tetras, calm rasboras and compatible bottom-dwelling fish can work when their temperature, group size and aquarium footprint are also met. Choose companions too deep-bodied to be viewed as prey and calm enough not to damage fins.
Dwarf and medium cichlids add their own territories. A combination that works outside breeding can change when one pair claims a site. Provide separate zones and never treat the word community as a promise of permanent peace.
| Companion type | Assessment | Why |
|---|---|---|
| Suitably sized peaceful shoaling fish | Often suitable | Can occupy open water without competing for the same territory |
| Compatible bottom fish | Often suitable | Uses a different region, if temperature and footprint also fit |
| Tiny tetras, fry or shrimp | Avoid | May be treated as prey |
| Fin-nipping fish | Avoid | Extended fins are easy targets |
| Other territorial cichlids | Use caution | Territories can overlap, especially during breeding |
| Another random single Angelfish | Use caution | Two fish can produce focused dominance rather than a compatible pair |
Browse the Angelfish shop, the broader Angel Fish category or the Pterophyllum scalare collection before choosing a size and colour form.
These links compare different products. They do not imply that the mixed fish supplied here will match another listing's colour, pattern or grade.
Confirm useful length and water depth, not only litres. Trace adult turning space around wood, plants, filter pipes and neighbouring territories.
The filter should be biologically mature with 0 mg/l ammonia and nitrite. Review several readings and the maintenance record rather than relying on one test immediately before checkout.
List every current fish at adult size. Decide what will happen if the Angelfish hunts tiny companions, a pair forms, or one cichlid becomes dominant. A separate mature aquarium or divider plan should exist before a conflict starts.
Choose this product only if an assorted domestic colour and pattern is welcome. Select a named form or individually photographed listing when one exact appearance is essential.
Test the aquarium, confirm the heater and filter, dim the lights and clear a calm release area. Do not add other new livestock or make a major aquascape change on the same day.
Follow the method supplied with the order because bag time and temperature affect the safest process. The acclimation timer can help organise the steps. Do not pour transport water into the display.
Use subdued light, avoid chasing the fish and offer only a very small feed after it has settled. Watch existing fish closely; a new arrival can alter an established hierarchy.
If there is an arrival problem, photograph the unopened bag and fish clearly and follow the evidence and reporting window in the livestock delivery and Live Arrival Guarantee terms. Keep the packaging until support confirms the next step.
Look for an upright body, even breathing, open fins, controlled swimming and interest in food after settling. The fish should be able to rest without being continually displaced by flow or tank mates.
Persistent darkening, clamped fins, hiding, rapid breathing, repeated chasing, loss of appetite or surface gasping calls for immediate checks of water quality, oxygenation, temperature and social pressure. Do not medicate before identifying the likely cause.
Check dorsal, anal and ventral fins for splits, white edges, redness or repeated damage. Correct fin nipping, sharp decor and water-quality problems before reaching for a treatment.
Modern ornamental-fish welfare research supports routine behavioural observation. Record who eats, who controls space, where each fish rests and whether the same individual receives repeated attacks. These patterns can reveal a problem before obvious injury appears.
The accepted identity, body form, Amazon-basin ancestry, environmental range, adult length and aquarium context are cross-checked against the FishBase Pterophyllum scalare account.
Social behaviour, enrichment and welfare interpretation draw on the peer-reviewed Journal of Fish Biology Angelfish welfare review and the group-size welfare study. The advice to avoid disruptive maintenance changes is informed by the Angelfish water-renewal and aggression experiment. Feeding frequency is interpreted conservatively from published Pterophyllum scalare feeding research.
Aquarium volumes and dimensions on this page are conservative retail husbandry interpretations. They are not claims that one number can remove hierarchy, breeding aggression or individual variation.
One live domestic Pterophyllum scalare is supplied per selected quantity in the supplier's XL 6-7 cm grade.
It means assorted domestic colour and pattern forms of the same freshwater Angelfish species. The exact appearance varies with the batch.
Not necessarily. The image is a representative owner-approved illustration, not a photograph of the individual fish selected for dispatch.
No sex is guaranteed. The supplier has not sexed this grade, and immature Angelfish cannot be reliably sexed from ordinary appearance alone.
No. Two unsexed fish are not a guaranteed compatible, bonded or breeding pair.
No. It is the dispatch grade. Plan for an adult up to about 15 cm total length with a much taller overall fin profile.
For one adult or an established compatible pair, plan around 180 litres, at least 100 cm length and roughly 50 cm useful water depth. A group needs substantially more space.
Yes, in a larger tall aquarium with visual barriers and a separation plan. Around 240 litres and 120 cm length is a starting baseline for a modest group, not a guarantee against aggression.
Use caution. Two unrelated fish can produce focused bullying. A compatible pair is established through behaviour, not simply by buying two animals.
Keep a stable 24-28 C and choose tank mates that share the same warm-water needs.
Aim for stable pH 6.0-7.8 and approximately 5-13 dH, with gradual acclimation where source and home water differ.
Use a quality tropical cichlid flake, granule or suitable pellet as the staple, with measured frozen or live foods for variety.
One or two small feeds daily is a practical home routine. Adjust to condition and remove uneaten food.
Suitably sized peaceful tetras can work. Very small tetras and fry may be hunted, while persistent fin nippers are unsuitable.
Small shrimp and shrimplets are at high risk of being eaten, so they are not dependable companions.
They can be graceful community fish, but they are social cichlids. Hierarchy and pair formation can lead to territorial aggression.
