A large, colorful species ofLeporinusoriginally known from the waters of the Guiana Shield,Leporinus arcusis relatively rare in the hobby. More recently, this species has been tank raised in limited numbers in Southeast Asia. A fast-swimming, but somewhat aggresive species, they make an excellent tankmate for large cichlids or characins, especially other active, fast-moving fish. As with most of their close relatives, the Lipstick Leporinus can be prone to nip fins or scales of slower moving tankmates and can be aggressive towards conspecifics or other close relatives. Plenty of cover and strong water movement can help offset aggression in these fish. If attempting to keep them together or with other close relatives, a group of at least 5 should be considered the bare minimum for successful cohabitation
