She extends her arms at night, to capture plankton or drift food. Non -symbiotic, very delicate maintenance (many plankton feeding if possible alive). Distribute food in clouds every day, in a soft laminar current, not directly on the animal otherwise, it will close and do not absorb anything. Crinoids have a night activity. Are closed by day, unless they are disturbed. Be careful, if disturbed, they will run away by contracting their arms, to go and put themselves elsewhere, causing a lot of risk with the brewing pumps usually present in the tank ... Never exhibit in the open air for aquarium transfers, this causes often fatal necrosis. Generally very sensitive animal.
