Description of Cerianthus Fish This anemone constructs a protective tube from mucus and sand. During the day, the anemone retreats into the tube, anchored in the substrate. At night, it preys on crustaceans and slow- swimming fish. In the aquarium, avoid housing it with creatures such as seahorses, which it will eat. Site it away from corals and other anemones, and take care not to touch its stinging tentacles.
