Kwajalein Butterflyfish (Chaetodontidae)

Butterflyfish are among the more conspicuous elements of the reefs at Kwajalein. Many species occur on virtually all lagoon, pinnacle and seaward reefs. They are generally fairly large and colorful, and usually wander about in the open during the day, most either defending a territory or wandering over a home range. Many species eat coral polyps, although a number of them feed on algae or benthic invertebrates such as small crustaceans and worms. Some species have a varied diet that includes a number of different kinds of foods. Although they have interesting colors and a usually non-aggressive nature, most butterflies do not do well in aquaria. Several of those that feed upon coral polyps will eat nothing else, making them very hard to maintain. Some of the home rangers with a more catholic diet really require more room to move around than they typically get in an aquarium. These pages show all the species currently known from Kwajalein, with the possible exception of Chaetodon tinkeri, but this is discussed under Chaetodon burgessi. It is possible that unrecorded species exist deeper than sport diving depths.
