Chaetodon zanzibarensis also commonly referred as the Poisson-Papillon of Zanzibar or Zanzibar Butterflyfish is distributed in the western half of the Indian Ocean from East Africa to the Chagos Archipelago.
The natural diet of the Zanzibar Butterflyfish consists mainly of coral polyps and benthic invertebrates. It inhabits rich coral growth areas at a depth of 3 - 30 m and generally found near Acropora and Goniopora growths.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.
