Aiptasia Eating Filefish / Matted Leatherjacket Filefish, Acreichthys tomentosus 
The Aiptasia Eating Filefish is a popular utility fish known for its natural appetite for nuisance Aiptasia anemones. With a mottled, camouflaged appearance and a gentle demeanor, A. tomentosus is a reef-safe-with-caution species ideal for hobbyists battling pest anemones. Its flattened body, subtle green-brown tones, and curious swimming style make it an interesting and functional addition to fish-only and select reef systems.
