The Yellow Pyramid Butterflyfish have fins that are yellow in color, and the body is mostly white. The white coloration forms a triangle with the yellow fins, lending it its common name. The head area is black helping these fish camouflage themselves in the wild.
The Pyramid Butterfly feeds upon plankton in the wild, and is safe for reef aquariums. The Yellow Pyramid Butterflyfish is quite shy at first, and should be provided multiple hiding places. The ideal aquarium should contain plenty of live rock that will provide hiding places, and a supplemental food source.
