A popular brackish water aquarium fish, the Scat occurs in three distinct color forms (green, silver, and red) which were once thought to be different species but are now all considered to be variants of the extremely widespread S. argus. Found along nearly every coastline of the Indo-Pacific region, scats are amphidromous, which means they regularly move between freshwater in marine habitats. Although they are sometimes marketed as a freshwater fish (and can be kept as such as juveniles), scats will do best in brackish or marine aquariums. The green scat is a t common color variant of S. argus, and is typically found in estuaries and mangrove forests. Although juvenile scats can tolerate pure freshwater for a while, they will need to be transferred to a brackish or full marine aquarium later in life. A social fish often found in large aggregations, they do well in groups of 5 or more.
