The Rainbow Basslet (Liopropoma fasciatum) has a primarily red and black body with yellow and pink lines running laterally from nose to caudal fin. L. fasciatum is more bold and curious than most in its family, and can be seen regularly swimming out in the open. They get rather large compared to most basslets, reaching a maximum length of 6 inches, and rely solely on a carnivorous diet. They must have plenty of room to swim, as well as a high protein diet consisting of mainly crustaceans.
