Scatophagus argus

Adults of the spotted scat can survive in fresh water, but are much less active than in salt conditions. This is a gregarious fish which requires vegetable supplements. The species 5. rubifrons (tiger scat) is probably only a variety of 5. argus. Scats are much more prone to disease if kept in fresh water, and thrive best in brackish or saltwater aquariums. Appears not to have been bred successfully by hobbyists; in any case, only reproduces in brackish water. Size: 20-25 cm.
