Notes: Brittle Starfish make excellent cleaners in the reef or fish only aquarium. They do not allow a piece of food to go unused and over time become domesticated to feeding, crawling out of their nooks to eagerly accept food provided from the aquarist. Larger specimens may prey on small, slow fish at night. Damaged arms are readily reproduced in the home aquarium.
† It has been reported that this species is a nocturnal hunter of small fish.
