The Yellow Pyramid Butterflyfish is also known as the Yellow Zoster Butterflyfish, and occurs in large numbers among the reefs of the Indian Ocean. The fins 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 will be at least 125 gallons and will contain plenty of live rock that will provide hiding places, and a supplemental food source. They may be kept singly, in pairs or small numbers. If underfed the Yellow Pyramid Butterfly may occasionally pick at Xenia or other soft corals. Feeding several times daily is recommended

The Yellow Pyramid Butterflyfish diet should consist of frozen and freeze-dried foods containing algae are good substitutes and can be supplemented with dried algae and vitamin enriched brine and mysis shrimp.
