The Aiptasia-eating filefish is a small marine fish popular in reef aquariums for its ability to control pest anemones, particularly Aiptasia and Majano. Native to the Indo-Pacific region, this species has a mottled, camouflaged appearance that helps it blend into coral environments. It is generally peaceful but can nip at soft corals or polyps, so caution is advised in mixed reef tanks. Filefish adapt well to captivity when provided with a varied diet, including frozen foods and algae, though their primary appeal is their natural tendency to consume nuisance anemones. They are hardy, relatively easy to care for, and considered an effective biological solution for Aiptasia infestations.
