Description
The Threadfin Leatherjacket is a small, camouflaged filefish known for its ability to consume Aiptasia anemones, making it popular in reef aquariums. It features a distinctive dorsal spine and a thread-like extension on its dorsal fin, blending well into its surroundings with mottled brown or grey coloration. While generally peaceful towards other fish, it may nip at corals and other invertebrates.
