The Seagrass Filefish, also known as the Bristletail Filefish, is a unique fish highly sought-after for a very specific reason: it is one of the only fish that reliably eats *Aiptasia* (pest anemones). It has a mottled green-and-brown, diamond-shaped body that provides excellent camouflage among plants and algae. Its temperament is peaceful, but it is not considered reef-safe. After it consumes all the *Aiptasia*, it is known to move on to eating zoanthids, LPS corals, and even some SPS polyps. An interesting fact is its ability to rapidly change its color and pattern to blend in with its surroundings, much like a chameleon.
