Carnivorous. Flake food, and marine pellets. Frozen Foods dipped in Zoe for vitamins, including bloodworms, silversides, prawns, krill, mysis shrimp, brine shrimp, clams, and squid.
Will sometimes fight with same species for territory.
Great for reef aquariums, best when kept in small schools will not harm any reef corals or inverts. Very easy fish to care for. Will do best within an aquarium with moderate to low lighting, as strong lighting will sometimes fade its bright colors. Can also be kept in an all fish aquarium with fish of the same temperament or lesser. One of the few species that the male and female are two completely different color variations, male having pink color with square pattern, female having an all bright yellow to orange color. see what you think here is the link:http://www.aquaticretail.com/default.php?cPath=22_23
