Andinoacara rivulatus

Andinoacara rivulatus, commonly known as the Green Terror for its aggressive behavior, is a strikingly beautiful cichlid known for its vibrant blue-green coloration. While they are captivating to look at, their aggressive nature means they should be housed with caution, ideally in species-dedicated setups or with other similarly sized and temperamentally matched fish. They require plenty of swimming space and ample hiding spots in the form of rocks or submerged roots.
