Also known as the hell fire anemone due to its very painful sting.
From the Indo-Pacific. Can reach 12 inches. Prefers moderate lighting. Has zooanthellae but also needs to be fed. Reported to kill fish. Minimum 50 gallon tank.
Does best in moderately strong currents, and needs a deep sand bed to bury its foot.
Actinodendron plumosum is a night emerging species. May bury itself in the sand. No clown fish naturally associate with it. Commensal Shrimp (Periclimenes) will host this anemone.
