Green Terror (Andinoacara rivulatus)

Green Terror Tropical Fish Learn all about the Green Terror's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Green Terror is the right fish for your aquarium.

The Green Terror is given an apt name, they are territorial, aggressive, and intolerant of other fish. Very hardy and robust fishes of a similar size may make suitable tankmates, although problems may always occur. Provide hiding spots amongst rocks and wood. The fish will adapt to a wide range of water conditions and is relatively easy to keep. Green Terrors are sometimes confused with the Blue Acara Aequidens pulcher which is a smaller and much more peaceful fish.

This fish is excluded from the Compatibility Checker as it is unsuitable for community aquariums or may require expert care.
