A medium-growing, active schooling fish, the Four Line Pictus Catfish is found throughout much of the Amazon, Orinoco, and Guyana Shield in South America. In the wild, they usually inhabit shallow water with medium to fast-moving current and typically shoal in large groups. A hardy aquarium fish, they should be given plenty of open space for swimming and are best kept in groups of 6 or more. They make an excellent addition to larger aquariums with peaceful South or Central American Cichlids.
