The Altum Angelfish is known from the upper Rio Negro and tributaries of the upper Rio Orinoco, including the Rio Atabapo and Rio Inarida. Here it inhabits the slower reaches of rivers, living amongst submerged roots and marginal vegetation. The Altum Angelfish is a majestic species which requires a taller than average aquarium, due to its potential adult height and long trailing finnage. Soft, acidic water with negligible hardness is requisite. Adults should never be housed with small fish (e.g. Neon Tetras) as they will quickly become a snack.
