Scatophagus argus belong to the scat family (Scatophagidae) and occur in 2 basic color morphs which are called Green Scat and Ruby Scat or Red Scat. As a whole, the species is called Spotted Scat. This fish is generally distributed around the Indo-Pacific region, to Japan, New Guinea and Southeastern Australia. They are quite popular aquarium fish. These fish are kept for their looks and curious behavior, especially in body structure resembling the famous discus fish. Unlike the delicate freshwater discus cichlids, the scats are hard fish of brackish and seawater that tolerate freshwater only when young. Otherwise they are fairly easy to keep, and they look very beautiful with black spots on their body.
