Rio Japura Albino Angelfish (Pterophyllum scalare)

Rio Japura Albino Angelfish (Pterophyllum scalare) is a pale, red-eyed freshwater angelfish with the high, triangular profile for which the species is known. The Rio Japura name is used in the aquarium trade for this distinctive line; "Albino" describes the light body and reduced dark pigment. It remains Pterophyllum scalare, rather than a separate species or a longer scientific name.

This listing is for one live juvenile fish at the supplied listing size of approximately 3-3.5 cm. The available source data does not define whether that measurement is body length, standard length or total length, so treat it as a guide rather than an exact fin-to-fin measurement. The fish is sold unsexed. Colour, pattern, fin length and body shape continue developing as a juvenile grows, and the individual dispatched will naturally vary from the representative gallery images.

Rio Japura Albino Angelfish at a Glance

What Does Rio Japura Mean?

Rio Japura is a trade-line name associated with angelfish linked in the hobby to the Japura river region of the Amazon basin. The spelling "Jappura" also appears in European stock lists. That background is useful for recognising the commercial line, but it is not proof that every fish sold under the name is wild caught or carries documented locality provenance. No wild-caught, F1 or collection-code claim is supplied for this individual, so this page does not make one.

The dependable identity is an albino form of Pterophyllum scalare. Expect a creamy white to pale pearlescent body, pink to red eyes, a laterally compressed shape and long dorsal, anal and ventral fins. The high-bodied silhouette can become much more pronounced with maturity. Juveniles often look less dramatic than adults, and normal variation means no two fish will have precisely the same colour intensity or finnage.

Adult Size and Aquarium Planning

A 3-3.5 cm juvenile can look suitable for a small aquarium, but freshwater angelfish do not remain small. FishBase reports a maximum of about 15 cm in total length and recommends an aquarium at least 100 cm long. Their extended fins also make water depth especially important. A practical long-term starting point is a mature aquarium around 120 litres or larger, at least 100 cm across and preferably 45 cm or more in water depth. A group, a territorial pair or a mixed community needs more room.

Do not use the juvenile delivery size to calculate permanent stocking. Plan around the adult fish, the number of other cichlids, sight lines and the open water left after decor. A larger footprint provides room to retreat if social dynamics change; extra height protects the dorsal and anal fins and allows the characteristic shape to develop without crowding.

One angelfish can be kept as a centrepiece in a compatible community. If you intend to keep a group, use a substantially larger aquarium and expect juveniles to establish a hierarchy. A pair may form as fish mature, at which point it can defend a spawning site. There is no reliable visual sex guarantee for a juvenile of this size.

Water, Filtration and Aquascape

Pterophyllum scalare is an Amazon-basin cichlid. Published species data spans 24-30 C, pH 6.0-8.0 and 5-13 dGH. For an established domestic angelfish, 25-28 C in stable, clean water is a sensible everyday target. Avoid rapid changes in temperature, pH or mineral content. Ammonia and nitrite should remain at zero, while nitrate is controlled through stocking, plant growth, maintenance and regular partial water changes.

Use efficient biological filtration with moderate rather than punishing flow. A tall planted layout with wood, broad leaves and vertical structure reflects the dense vegetation associated with the species while still leaving open lanes for swimming. Position hard decor so long fins cannot be trapped or torn. Shaded areas are useful for a pale albino fish, but normal aquarium lighting is suitable when the fish can choose between bright and sheltered zones.

A secure lid is sensible. Keep heater guards and filter intakes appropriate for a small juvenile, and make sure food reaches it if larger residents dominate the surface. Before ordering, compare the full setup with our freshwater angelfish care guide, not only the fish's current size.

Angelfish Tank Mates

The best angelfish tank mates are calm, non-nipping fish that share warm-water requirements and are too large to be viewed as prey. Medium-sized peaceful tetras, appropriately kept Corydoras, calm rainbowfish and selected peaceful catfish can work in a roomy aquarium. Compatibility is never guaranteed by a species list alone: tank dimensions, group size, age, feeding competition and individual temperament all matter.

Watch behaviour rather than assuming that a peaceful juvenile will always remain passive. Repeated chasing, clamped fins, torn fins, hiding at the surface or one fish being excluded from food are reasons to intervene. Browse the wider angelfish collection to compare strains and sizes before planning a group.

Feeding a Juvenile Albino Angelfish

Offer a varied omnivore diet built around a quality tropical or cichlid flake, soft granule or small pellet sized for the fish's mouth. Rotate suitable frozen foods such as brine shrimp, daphnia, mysis and bloodworm, and use responsibly sourced live foods where appropriate. A varied diet supports growth and condition more reliably than relying on one rich food.

Young fish usually do well with small portions two or three times a day, provided all food is eaten promptly and water quality remains excellent. Adults can be fed less frequently. Angelfish quickly learn a feeding routine and may become assertive, so observe that quieter tank mates also eat. Remove uneaten food and do not use heavy feeding as a shortcut to fast growth.

Behaviour, Pairing and Breeding

Freshwater angelfish are intelligent, observant cichlids that learn where and when food appears. Juveniles may associate loosely, but mature fish form hierarchies and compatible pairs. A bonded pair may clean a broad leaf, slate or another vertical surface and lay eggs in rows. Both parents can guard the eggs and territory, which is interesting natural behaviour but can make a previously calm community tense.

This product is one unsexed juvenile, not a breeding pair. Sex, future pairing, fertility and breeding success are not guaranteed. Anyone building a group should provide substantial space, visual barriers and a plan to separate a fish if courtship or dominance becomes relentless.

Comparing Similar Angelfish

These are all angelfish, but colour name alone should not decide compatibility. Compare supplied size, adult space, social plan and the needs of fish already in the aquarium.

Arrival and First-Week Care

1. Prepare a fully cycled, heated aquarium before dispatch and test the water.
2. On arrival, keep the bag out of bright light and follow the included instructions or our acclimation timer.
3. Keep aquarium lighting low for the remainder of the day and offer only a small first meal once the fish is settled.
4. Check breathing, balance, fin posture, appetite and interactions with established fish.
5. Use quarantine where practical, particularly before adding a new fish to a valuable established collection.

Frequently Asked Questions

Is Rio Japura Albino a separate angelfish species?

No. The scientific identity is Pterophyllum scalare. Rio Japura Albino is the commercial line or form name, not an extra part of the scientific name.

How many fish are included?

One product quantity includes one live juvenile angelfish. It is not a pair or a group.

Is the juvenile male or female?

It is sold unsexed. Sex cannot be guaranteed from a juvenile of this size, and future pairing is not guaranteed.

How large is the fish when supplied?

The supplied listing size is approximately 3-3.5 cm. Because the source does not specify body, standard or total length, allow natural measurement and individual variation.

How large will it become?

Plan for up to about 15 cm total length and considerably more height when the extended fins are included. Use a tall aquarium at least 100 cm long rather than planning around the juvenile size.

Can it live with neon tetras?

There is a predation risk once an angelfish matures because very small, slender fish can fit in its mouth. Choose larger peaceful companions and assess the actual size difference.

Will it look exactly like the gallery fish?

No. The images represent the named form. Live fish vary in colour, pattern, fin development, body shape and supplied size, especially while juvenile.

Is it suitable for a beginner?

It is better described as moderate care. A prepared keeper with a mature tall aquarium can succeed, but adult size, water stability, feeding and cichlid behaviour require more planning than a small peaceful shoaling fish.
