This little beauty should generally be avoided by hobbyists because it feeds exclusively on coral polyps and rarely accepts aquarium fare. This species is usually indifferent toward its tank mates, with the exception of members of the same species. However, you can usually keep a pair or a small group of these fish if they are added simultaneously. It should only be kept with more docile species. Provide branching corals (either live, dead, or fake) for it to take refuge in when threatened or at rest.
