What do Altum Angelfish eat?
Since they are omnivorous, the Altum Angelfish will generally eat all kinds of live, fresh, and flake foods. To keep a good balance, give them a high quality flake food or pellet every day. Feed brine shrimp (either live or frozen) or blood worms as a treat. You can even feed them lettuce or spinach.
Where are Altum angelfish from?
Pterophyllum altum, also referred to as the altum angelfish, deep angelfish, or Orinoco angelfish, occurs strictly in the Orinoco River Basin and the Upper Rio Negro watershed in Southern Venezuela, Southeastern Colombia and extreme Northern Brazil.
What kind of fish is the Peruvian altum?
Ultimately, ichthyologists concluded that the Peruvian Altum is probably some sort of Pterophyllum scalare endemic to the Rio Nanay. There seem to be distinct populations of Pterophyllum scalare across the Amazon and Orinoco region, such as the ‘red shoulder’ Manacapuru variety sometimes seen in the better aquarium shops.
Are there different types of Pterophyllum altum fish?
Modern studies into the genetics of the genus confirmed the separation of the three species, and within Pterophyllum altum and Pterophyllum scalare, further distinct populations have been found. Within Pterophyllum altum for example, the upper Rio Negro and upper Orinoco populations appear to be distinct.
Is the Peruvian altum the same as the Manacapuru?
Genetic analyses support at least some of them: the Manacapuru and Santa Isabel are robustly supported, but the Peruvian Altum less so, implying fewer genetic differences.
Where was Pterophyllum altum found in the world?
At the time Schultz was writing, Pterophyllum altum had only been reported from the upper Orinoco basin. His hesitancy about separating the two species came down to whether the Altum Angel was simply a geographical limited variant of the Common Angelfish.
