Genicanthus lamarck also known as Lamarck's angelfish, Swallowtail Angelfish and Black Striped angelfish is found in the wild from the Solomon Islands and New Hebrides northward to Japan.
Genicanthus lamarck is one of the few angelfishes that show a sexual dismorphism; male has a yellow spot on its forehead and longer more pointed caudal fin. Both, male and female have been often described as different species because of these differences. Lamarck's angelfish is fairly easy to keep, not a spectacular beauty but an interesting and hardy even an sometimes somewhat shy angelfish. Some adults may pummel small zooplankton feeders such as Wrasses, Anthias and Gobies.
Feeds like all of his genus mainly on plankton, crustaceans, and macro algae in the wild. Genicanthus lamarck needs a varied diet and numerous feedings per day. Feed prepared and frozen foods in captivity, as well as providing live rock to graze upon.
There are not many angelfish appropriate for the reef tank, of the ones that are, the Black Striped angelfish is like most of his genus one of the best and well suited for the reef aquarium, but may occasionally nip xeniid and large-polyped stony corals.
