Spinecheek anemonefish and their host anemones have a mutualist relationship. Entacmaea quadricolor benefits from having spinecheek anemonefish protect them from butterflyfish (Chaetodontidae), which would otherwise eat their tentacles. Spinecheek anemonefish also clean away debris and parasites from the anemone. Spinecheek anemonefish are protected from most predators through their association with venomous anemones.
