Pterophyllum scalare platinum panda

Choose this tall South American cichlid for a prepared aquarium

The platinum panda angelfish (Pterophyllum scalare) is a freshwater cichlid from South America’s Amazon basin that reaches 15 cm. Its native range includes Brazil, Colombia, French Guiana, Guyana and Peru. This tall-bodied colour form suits a prepared keeper with a mature aquarium, room for an adult pair or deliberately managed group, and a plan for occasional territorial behaviour. It is not a small, passive community fish simply because the dispatch fish is compact.

FishBase identifies Pterophyllum scalare in the family Cichlidae and describes adults living around dense aquatic and river-edge vegetation in swamps and flooded ground. The platinum panda form keeps the characteristic laterally compressed angelfish shape while adding pale platinum colouring and bold black panda-like markings. Eschmeyer’s Catalog of Fishes also accepts the name Pterophyllum scalare.

We classify its care level as intermediate. Routine feeding is straightforward, but adult height, social dynamics, long fins and possible breeding aggression require more planning than a typical small community fish.

Plan around adult length and fin height

Plan for an adult length of 15 cm, with extended fins that can make the fish roughly 20–25 cm tall. Length alone therefore understates the vertical space an adult angelfish uses. FishBase also carries a current field maximum of 10.5 cm total length, while the familiar aquarium planning figure is 15 cm; use 15 cm for the adult plan rather than designing around the smaller observation.

For an adult pair, start with roughly 200 litres, a footprint around 100 × 40 cm and about 50 cm of usable height. Seriously Fish recommends a 100 × 40 × 50 cm aquarium of about 200 litres as the smallest arrangement to consider. Our complete freshwater angelfish care guide uses that as the preferred planning point for an adult pair.

OATA gives 120 litres as an industry floor for a compatible pair of smaller American cichlids and says an angelfish aquarium must be sufficiently tall. The 200-litre plan adds more useful height, turning room and territory. A group or community needs more space because nominal volume cannot replace floor area, sight breaks or a route for separating incompatible fish.

Understand the animal and size supplied

One purchase supplies one platinum panda angelfish in the size selected on the page. Use the live size selector to choose from the displayed labels, which may include 3–3.5 cm, 3.5–4 cm, 4–4.5 cm, 4.5–5 cm and 5–5.5 cm. The size you select is the size supplied, not the adult size. Build the aquarium around the 15 cm adult length and substantial fin height, even when choosing a smaller dispatch fish.

Sex is guaranteed only when the selected option explicitly states male or female. This Pterophyllum scalare platinum panda listing has no sex-guaranteed option.

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.

The pictured form shows why “platinum panda” is a useful visual name: pale silver-white colour is interrupted by dark patches around the eye, body and tail area, while tall translucent fins preserve the familiar angelfish outline. Individual pattern placement and colour intensity can vary without changing the adult care plan.

If you are comparing this form with other shapes and colours, browse the angelfish collection after checking that the aquarium can meet the same adult-space and social decisions.

Build in height, turning room and sight breaks

Give an adult angelfish enough clear height to hold its dorsal and anal fins naturally, plus horizontal room to turn without brushing decor. A nominally large but shallow aquarium can fail this test. Aim for about 50 cm of usable height within the roughly 100 × 40 × 50 cm adult-pair plan, measuring the space after substrate, wood and equipment have been added.

Use vertical structure without crowding the fish

Arrange tall leafy plants or upright wood to create visual barriers, then preserve open water between those barriers. FishBase describes wild adults around dense vegetation in clear or silty flooded habitats, so vertical planting is useful layout inspiration. It also lets a fish move out of an aggressor’s direct line of sight. Structure should divide territory rather than form a narrow obstacle course for long fins.

• Keep edges smooth: long dorsal, anal and ventral fins can be damaged by sharp rock, rough ornaments or exposed equipment.
• Secure the layout: cichlids may dig or sift the substrate, so unstable decor can become hazardous.
• Leave turning space: test the route around wood and plants against the adult body and fin height, not the dispatch size.
• Protect equipment: cover hazardous filter intakes and keep cables or heater guards from forming fin traps.
• Fit a secure lid: keep access practical for feeding, testing and maintenance while closing escape gaps.

Fine aquarium gravel or sand fits OATA’s general American-cichlid guidance. Live plants may be disturbed, so position them securely; robust planted zones, roots and wood can provide cover without filling every part of the aquarium. Gentle water movement suits the species, but gentle flow still requires effective filtration and oxygen exchange.

Before committing to a layout, view it from each end of the aquarium. If every fish can see every other fish across the full length, add a plant or vertical feature. If an adult could not turn without bending fins around that feature, open the route again.

Keep water inside the shared routine range

Keep routine conditions at 24–27°C, pH 6.5–7.4 and 5–12 dGH. These values are the overlap of the species ranges from FishBase and Seriously Fish with OATA’s wider American-cichlid guidance. FishBase gives 24–30°C, pH 6.0–8.0 and 5–13 dGH; Seriously Fish gives 24–30°C, pH 6.0–7.4 and 0–15 dGH; OATA gives 22–27°C, pH 6.5–8.0 and 4–12 dGH.

Choose a stable point inside the routine range instead of repeatedly adjusting towards the middle. A fish held at 25°C and pH 7.0 gains nothing from daily correction towards an imagined perfect decimal. Temperature, pH and hardness changes should be measured and gradual, while detectable ammonia or nitrite requires urgent action.

Measure before changing the water

• Temperature: check with a thermometer rather than relying only on the heater dial.
• pH: compare results over time and note whether a change follows a water change, new decor or altered maintenance.
• GH and KH: measure both before mixing tap water with reverse-osmosis water or adding mineral products.
• Ammonia and nitrite: keep both at zero detectable levels.
• Nitrate: OATA advises keeping it no more than 20 mg/l above the normal tap-water level.

Use our water chemistry guide to understand what each test measures, then use the water matcher to compare measured aquarium values with the routine range. A fixed tap-and-RO recipe is unsuitable because source water differs between homes.

If pH or hardness drifts, identify the reason before adding another product. Test the source water, check the aquarium result and review recent changes. Consistency within the stated range is safer than repeated swings caused by treating each isolated reading.

Cycle the filter and maintain measurable water quality

Add the fish only after the aquarium has a functioning biological filter and tests show zero detectable ammonia and nitrite. The RSPCA explains that biological filtration supports bacteria that convert toxic ammonia to nitrite and then to the safer nitrate. Elapsed time alone cannot show whether that process is handling the aquarium’s waste.

If this is your first setup, follow the steps in our first tropical aquarium guide before arranging livestock. Test the system under its expected routine, ensure temperature is stable and add fish gradually so feeding and waste do not overwhelm the developing bacterial population.

Use a repeatable maintenance routine

1. Test ammonia, nitrite and nitrate at least weekly, and test promptly whenever behaviour, breathing or appetite changes.
2. Use a partial water change of about 25% each week as OATA’s starting routine, then adjust according to measured nitrate, stocking, feeding and filter performance.
3. Treat replacement tap water with a conditioner that handles chlorine or chloramine before it enters the aquarium.
4. Use a siphon to remove trapped solid waste from accessible substrate without dismantling the whole layout.
5. Check the filter for reduced flow or blockages during maintenance.
6. Rinse dirty biological media lightly in water removed from the aquarium, never under the tap, protecting the bacteria living on it.

Seriously Fish suggests turnover of four to five times aquarium volume per hour for an aquarium around 200 litres, corresponding to a filter rating around 800–1000 litres per hour. Treat that as a starting specification: media condition, pipework and head height affect real flow. Position the outlet so the surface moves and oxygen exchange continues without forcing the angelfish to battle a harsh current throughout the aquarium.

Check each fish after maintenance. A prompt return to steady swimming and normal breathing supports the routine; persistent gasping, clamped fins or loss of balance calls for immediate testing. Never wait for cloudy water before checking a system that contains live fish.

Feed a complete diet in measured portions

Use a nutritionally complete cichlid pellet, granule or suitable flake as the staple, choosing a size the fish can swallow easily. Add appropriate frozen or freeze-dried foods for variety. Seriously Fish describes the species as omnivorous and notes that wild fish feed predominantly on zoobenthos such as small crustaceans and other aquatic invertebrates, while aquarium fish accept dried, live and frozen foods.

OATA advises feeding American cichlids once a day and giving only what they can consume within a few minutes. That group guidance provides a useful portion rule: begin conservatively, watch every fish eat and stop before food settles into plants or substrate. Remove uneaten food because decomposing leftovers increase the waste load handled by the filter.

Build variety around a complete staple

• Routine staple: complete cichlid pellet, granule or suitable flake.
• Measured variety: appropriately sized frozen or freeze-dried foods.
• Named examples: daphnia, brine shrimp and bloodworm suit the smaller American-cichlid feeding examples in OATA’s guidance.
• Access check: confirm that every fish receives food instead of relying on what the quickest fish consumes.
• Waste check: reduce the next portion if food remains after a few minutes.

A controlled angelfish feeding study found that feed composition affects growth and reproductive performance. It supports using a considered diet, while the once-daily, few-minutes routine provides the practical household schedule.

Watch body profile and feeding response over time. A fish that rushes to food can still monopolise more than it needs, while a timid fish may lose condition despite food entering the aquarium. Spread suitable portions across more than one nearby point when some fish are being excluded, but keep the total within the amount the group finishes promptly.

Manage a compatible pair or group deliberately

Keep angelfish with a deliberate social plan. FishBase gives groups of five or more for aquarium keeping, while OATA advises a pair or group at minimum and warns that a solitary angelfish may become stressed. Seriously Fish describes the species as generally peaceful but notes that individuals may squabble with their own kind. A group of at least five is therefore a starting social number, not permission to crowd five adults into the pair-sized aquarium.

Choose the plan before the fish mature

Two randomly chosen fish are not automatically a compatible pair. Juveniles can grow together and form their own pair preferences, but some fish may lose access to food and shelter. Once a pair claims an area, another fish may be repeatedly chased even when the aquarium previously looked calm.

Check the group at feeding time and again when no food is present. Repeated hiding, one fish being pinned behind equipment, damaged fins, weight loss or exclusion from food indicates that the arrangement needs action. Add or reposition sight barriers only when the aquarium still retains adequate swimming room; separate or rehome fish when structure cannot stop persistent conflict.

Prepare the exit plan before pair formation. A second mature, heated and filtered aquarium is more useful than an empty emergency container. If rehoming is the intended route, decide where the fish can go while all animals are still in good condition rather than waiting for injuries.

Prepare for arrival and acclimatise slowly

Before the parcel arrives, use OATA’s care guidance to confirm that the aquarium is mature, heated and filtered, with zero detectable ammonia and nitrite. Recheck temperature, pH and the planned social arrangement before introducing another fish. Adding livestock slowly gives the biological filter time to respond as feeding and waste increase.

Tropical Fish Co hand-bags live fish in pure oxygen, uses an insulated poly box and adds a heat pack when the weather calls for it. A licensed live-animal courier carries the parcel. The current packing, reception and claim terms are set out in our delivery and Live Arrival Guarantee policy.

Follow the store arrival steps

1. Have someone present to receive the parcel.
2. Start filming before the parcel is opened, showing the parcel still sealed and the outer box visible.
3. Continue filming in one take while opening the parcel and showing the fish still inside the bag.
4. Float the bag in the aquarium for 20–30 minutes before releasing the fish.
5. Release the fish without pouring the bag water into the aquarium.

After release, observe swimming, balance and breathing without immediately rearranging the whole aquarium. Check that existing angelfish or other territorial fish do not trap the newcomer in a corner. General settling-in advice from OATA is to monitor behaviour and appearance closely, particularly swimming, colour, breathing, aggression, hiding and feeding.

During the first week, compare each observation with the fish’s own earlier behaviour. Check that it can reach food, hold its fins openly and move through the layout without being chased continuously. Test water promptly if breathing quickens, appetite falls or swimming changes. A new arrival can reveal a filtration or compatibility problem quickly, so respond to measurements and repeated behaviour rather than waiting for visible injury.

Test the water first when health changes

Healthy angelfish normally show steady swimming, regular breathing, clear eyes, open undamaged fins, a consistent body profile and reliable feeding. Warning signs include gasping, clamped or damaged fins, flashing, white spots, wounds, unusual balance, isolation, marked colour change or a sudden change in appetite.

The RSPCA’s fish health guidance supports a water-quality-first response. Test ammonia, nitrite, nitrate and temperature immediately, then check pH where relevant. Treat detectable ammonia or nitrite as urgent because both are toxic. Compare every result with the aquarium’s established readings instead of changing several conditions at once.

Respond in a controlled order

1. Measure: record water results, the affected fish, visible signs and when the change began.
2. Correct urgent water faults: use conditioned replacement water and protect biological filtration.
3. Check compatibility: look for chasing, blocked access to food, wounds or a fish confined to one area.
4. Separate only into a suitable system: an immature or unheated container can add further stress.
5. Obtain a diagnosis: contact us or a fish vet when signs persist, worsen or involve breathing, balance, wounds or rapid loss of condition.

Do not treat white spots, abnormal faeces, head marks or unusual swimming as proof of one disease. Medication choice depends on the actual problem, the fish, the aquarium and the product label. In the UK, use only a lawful treatment labelled for the species and system, following its instructions or veterinary direction.

If an angelfish jumps out, return it to suitable aquarium water immediately using wet hands or a wet, soft net. Minimise handling, monitor breathing and balance, then check the lid for gaps. Seek fish-veterinary advice if recovery, skin or movement remains abnormal.

Screen every companion before mixing

Choose companions by adult size, fin behaviour, temperament, territory, water requirements and feeding speed. Angelfish can live in a robust community, but their cichlid behaviour and tall fins create two different risks: they may defend territory, and they may be injured by persistent fin-nippers. The outcome also changes when a pair forms or begins breeding.

OATA names appropriately robust, larger shoaling fish as a possible community category for calmer American cichlids such as angelfish. Seriously Fish warns that small fish such as tetras may be eaten. That means “tetra” alone is not a compatibility decision: compare the exact species at adult size and avoid small fish that may be swallowed.

Corydoras and bristlenose plecos are sometimes considered because they use different aquarium levels, but species, adult size, floor space and water needs still determine the fit. Avoid shrimp and fry because they remain at predation risk. Another angelfish also needs careful assessment because shared identity does not prevent territorial conflict.

Compatibility remains conditional because individuals, pair bonds, aquarium dimensions and existing territories change the result. For a specific stocking assessment, contact us with the aquarium dimensions, measured water values, filtration, existing inhabitants and adult social plan. Keep a mature separation route ready whenever territorial fish are mixed.

Respond early to pairing and territorial behaviour

Expect occasional territorial behaviour, especially within the angelfish group and around pair formation. A fish that gives a brief chase and then resumes normal activity presents a different situation from one that repeatedly traps another fish, blocks food or causes fin damage. Judge the pattern, frequency and effect on the targeted animal.

Use behaviour as an action trigger

• Brief display with normal feeding: continue close observation and preserve multiple routes around sight barriers.
• Repeated exclusion from food: spread measured food across suitable points and prepare separation if equal access does not return.
• Persistent cornering or fin damage: separate the fish using a mature, heated and filtered arrangement.
• A pair defending a vertical surface: treat the area as an active territory and reassess every other inhabitant’s space.
• Community fish crowding one level: adjust the stocking plan rather than assuming unused litres solve the conflict.

Angelfish lay adhesive eggs on vertical surfaces such as broad leaves, slate or aquarium glass, and both parents may guard eggs and young. Breeding can intensify territorial defence sharply. A dedicated mature setup gives a compatible pair and any fry a safer route than expecting a crowded community to absorb the change.

Pair choice matters, and a selected pair is not guaranteed to remain bonded for life. Sexing can be difficult outside active spawning; visible breeding papillae may assist during spawning, while forehead shape, fin angle or temperament should not be used as a reliable juvenile sex test. Plan the group and space without depending on visual sex assumptions.

Review the aquarium after any pairing change. Check feeding access, fin condition, hiding, chasing and use of space every day until the social pattern settles. Repeated injury or loss of condition calls for separation, not additional waiting.

Answer common platinum panda angelfish questions

How big does Pterophyllum scalare platinum panda get?

Plan for an adult length of 15 cm. Its extended fins can make an adult roughly 20–25 cm tall, so provide substantial usable height as well as horizontal turning room.

What size aquarium does Pterophyllum scalare platinum panda need?

Plan roughly 200 litres with about a 100 × 40 cm footprint and 50 cm usable height for an adult pair. A group or community needs more space, visual barriers and a separation plan.

How many Pterophyllum scalare platinum panda should I keep?

FishBase gives groups of five or more, while OATA advises a pair or group at minimum and warns that a singleton may become stressed. A group of at least five needs substantially more room than the roughly 200-litre adult-pair plan.

Does Pterophyllum scalare platinum panda suit beginners?

We classify it as intermediate because feeding is straightforward, but its 15 cm adult length, substantial fin height, group management and possible breeding aggression require a mature aquarium and an active separation plan.

What does Pterophyllum scalare platinum panda eat?

Feed a complete cichlid pellet, granule or suitable flake as the staple, with appropriate frozen or freeze-dried variety. OATA advises one daily portion that the fish finish within a few minutes.

What temperature and pH does this fish need?

Keep it at 24–27°C, pH 6.5–7.4 and 5–12 dGH. These routine values are the overlap of the FishBase and Seriously Fish species ranges with OATA’s wider American-cichlid guidance.

Is the platinum panda angelfish aggressive or likely to nip fins?

It is generally peaceful but may squabble with its own kind and become territorial around pairing or breeding. Protect its long fins from persistent fin-nippers and separate fish if chasing causes exclusion or damage.

Which animals can it live with?

Appropriately robust, larger shoaling fish may suit a spacious community when adult size, water and feeding behaviour match. Avoid very small fish, shrimp and fry because they may be eaten; Corydoras and bristlenose plecos still require species, floor-space and water checks.

How does the platinum panda angelfish travel to my home?

Tropical Fish Co hand-bags the fish in pure oxygen, uses an insulated poly box and adds a heat pack when weather calls for it. Someone must receive the parcel and film continuously from the sealed parcel through opening and showing the fish in the bag, then float the bag for 20–30 minutes before release and never pour bag water into the aquarium.
