Filefish

Tankmates: Reef-safety varies: Acreichthys may nip zoanthids and soft corals once Aiptasia is gone; Oxymonacanthus eats Acropora polyps; larger species nip corals and clams.

Feeding: Most accept frozen foods. Oxymonacanthus eats Acropora polyps and rarely adapts to prepared foods - generally unsuitable. Acreichthys is bought to eat Aiptasia but also needs other food.
