Not Suitable for Fish-Only Tank
The members in the Order Dentrochirotida and families Cucumariidae and Phyllophoridae are suspension feeders, and require frequent feedings with plankton-like foodstuffs.
Those in the family Phyllophoridae live buried in sand or loose rock and extend their feeding tentacles into the water, while those in the family Cucumariidae cruise the substrate while suspension feeding.
Toxic when stressed or dies, therefore remove specimens that appear not to be doing well! (See the Introduction to this Section on Sea Cucumbers!)
