Angelfish

Pterophyllum scalare
French name : Scalaire

The angelfish is a widely kept cichlid (family Cichlidae) native to the Amazon basin and associated South American rivers. It has a laterally compressed, disk-shaped body with tall dorsal and anal fins and trailing pelvic filaments; wild fish are silver with dark bars, while decades of breeding have produced many color and finnage varieties. It is generally peaceful but is a cichlid, so it can be territorial, especially when paired and breeding. It is often kept in groups when young, from which pairs form naturally. A tall aquarium with warm water, driftwood, and tall plants mimics its habitat. It is an omnivore accepting flakes, pellets, and frozen and live foods. Very small tankmates may be eaten, and long-finned fish may be nipped, so companions should be chosen carefully. Pairs readily spawn on vertical surfaces and guard their eggs and fry, making it a rewarding beginner-to-intermediate cichlid.

Rio Nanay
Wild locality from the Rio Nanay in Peru: a slender, silvery fish with a warm brownish sheen and fine barring. Wild forms are more demanding than farmed strains — soft, acidic, warm water and impeccable quality.

Rio Negro
Rio Negro
Wild locality from the Rio Negro (Brazil), the blackwater river: tall-bodied with contrasted bars and reddish glints in the eye and fins. Like all wild forms, it wants soft, acidic, tannin-stained water.

Dantum
Dantum
A COMMERCIAL strain — neither a wild locality nor an altum. The name is a trade brand: a contraction of the wholesaler Dantziger and "altum". It is a farmed Pterophyllum scalare, tall-finned and silvery, that does not exist in the wild. Often resold as "Peruvian altum" or "albino altum", which is incorrect: true Pterophyllum altum is a different species, far more demanding.
