Matted Filefish   (Acreichthys tomentosus)
Family: Monacanthidae (Filefishes)
Natural Range: Indo-Pacific Region
Depth: 7 to 49 ft.   Size: 3.5 in.   Jumps: No   Space: 30+ gal.
Reef Safe: Caution   Care Level: Moderate   Temperament: Peaceful
Diet: Amphipods, bristleworms, molluscs
Natural History: The Matted Filefish is found in sallow reef zones with macroalgae and rubble. This species is commonly associated with 'seagrass' habitats where it is both camouflaged and has an ample food source. Males are slightly larger than females and have more bristles on their caudal peduncle. This fish 'stands on its mouth' in an effort to behaviorally camouflage in its seagrass environment.
Husbandry: The Matted Filefish is unaggressive toward unrelated species but aggressive toward its own. It is known to eat Aiptasia in the home aquarium, but will also nip at the polyps of stony corals. It will normally 'stand on its mouth' when alarmed in an attempt to camouflage in its environment.
Reproduction: This species has bred in captivity.

AKA: Bristle-tail Filefish, Aiptasia-eating Filefish, Matted Leatherjacket
