Green terror (Andinoacara rivulatus, syn. Aequidens rivulatus) is a very bright colored cichlid and its body is covered with bright blue scales. But this is not all about her rich color, it also behaves in a very interesting way.
Green terror is a commom name for all three sub species: Andinoacara stalsbergi, Andinoacara sp. Gold/Silver saum and Andinoacara rivulatus.
This kind of fish is often mistaken for another very alike fish – Aequidens pulcher.
There were the times when these two fishes were considered as one kind. However, nowadays they were divided into two different kinds. Although the fishes are alike, they have some significant differences.
