Peruvian Altum Angel

The Peruvian Altum Angelfish (Pterophyllum scalare “Peruvian Altum”) is a rare species of angelfish. It has an unusually long body for its species and was often mistaken for the rare real Altum Angelfish (Pterophyllum altum), which is often collected in the wild and considerably less durable than P. scalare. The extremely tall body shape is not as noticeable in juveniles, but becomes considerably more noticeable as this fish matures.

When compared to other members of the cichlid family, this shoaling cichlid is quite tranquil. In addition, unlike most other cichlids, it has a very slender, tall body. Although the Peruvian Altum Angelfish is native to various river systems in Northern South America, almost all specimens in the aquarium hobby have been tank-raised.

II. You would love the fish because…

The Peruvian Altum Angelfish will thrive in a well-planted aquarium with driftwood and/or rock formations, as well as a slow water flow. This fish is not very shy, although it prefers the shelter of plants and, due to its body form, is unlikely to seek safety in rock caves and similar structures.

As long as it has lots of space, the Peruvian Altum Angelfish is generally amicable with other peaceful fish. During spawning, territoriality is usually at its height. Dwarf shrimp and other small, delicate invertebrates should not be housed with Peruvian Altum Angelfish, but larger, more durable shrimp and snails may make suitable tankmates in a large enough aquarium. If spawning is desired, other species’ tankmates should be kept to a minimum or avoided altogether unless the aquarium is very spacious.

III. Is this fish species peaceful or hostile?

Generally docile, yet territorial during spawning.

IV. Species compatibility

Similar aggressive fish such as clownfish, dottybacks, damselfish, tangs, and wrasses are excellent tank mates for a Blue Angelfish. It is recommended that the Blue Angelfish be added last to a tank with similar temperament species for the best results.

V. How to feed this species?

Angelfish feed at the surface or in the middle of the water, but in the wild, they graze along the bottom for worms and small crustaceans. They are omnivores and can be fed Aqueon Tropical Flakes, Color Flakes, Tropical Granules, and Shrimp Pellets.
