usually found in the coral rubble at the base of the reef aquarium, with some of the rubble being incorporated into its parchment-like tube. It needs to be housed in a well-established reef system as it is dependent upon plankton for its diet. It is very intolerant of copper-based medications.
Regular direct feedings with micro-vert or phytoplex would be my suggestion. From what I have read these can be really difficult to sustain and are best left on the reefs.
