Aiptasia Eating Filefish

The Aiptasia Eating Filefish (Acreichthys tomentosus) is a hardy and peaceful saltwater fish best known for its ability to naturally control nuisance Aiptasia anemones in reef aquariums. Its mottled camouflage pattern helps it blend into rockwork, while its calm demeanor makes it suitable for community tanks. This utility fish is an effective and natural solution for Aiptasia outbreaks, though occasional nipping at corals may occur in delicate reef setups.
