Purple Sponge Brittle Starfish

Range: Indo-West Pacific Ocean

Natural Environment: Inhabits rocky shallow coastal areas and is found clinging to sponges, gorgonians, and corals.

General Husbandry: Rarely seen in the trade.

Best maintained in aquaria with live rock caves where it can hide during daylight hours and since this is a scavenger, its best not placed in new systems.

During evening hours will search the substrates for organic matter.

A valuable member of a cleanup crew, as it will forge for uneaten foods. Nevertheless, to be sure its getting the nutrition needed, placing several shrimp pellets in dark corners of the aquarium in early evening hours a couple of times monthly may help lengthen its lifespan.
