The Zoster Butterfly, also known as the Black Pyramid Butterfly, occurs in large numbers among the reefs of the Indian Ocean. They are black in color with a wide vertical white band covering the middle of the body. The dorsal fin is colored in the same pattern as the body, but has the addition of yellow on the tips of the white band.
The Zoster Butterfly is quite shy and should be provided with multiple hiding places. The ideal aquarium will be at least 125 gallons and will contain plenty of live rock that will provide cover from the light and a supplemental food source. If underfed the Zoster Butterfly may occasionally pick at xenia or other soft corals. Feeding several times daily is recommended.
The Zoster Butterflies 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.
