Very few fish show sexual dimorphism, out of those few the Zebra Angelfish, Genicanthus caudovittatus, is one of them. Male Zebra Angelfish have the zebra-like stripes with a forked tail while the female has a light blue body with a black band covering its eyes also with a forked tail. Since they are more peaceful than many other Angelfish, they can be kept as a mated pair, or in a small school of females. Avoid keeping two males in the same tank, as it can lead to extreme aggression.
However, they are not reef safe, as they will nip at soft and stony polyp corals, sessile invertebrates and clam mantles.Diet should include a variety of spirulina, marine algae, high quality angelfish preparations, mysis and brine shrimp, 3 times daily.
