Natural History: Tosia Sea Biscuits are echinoderms that move with tube feet. They control their tube feet with an internal water vascular hydraulic system. Tosia is commonly observed on reef rubble and rock. It is generally believed that this starfish preys on the film of algae and tiny invertebrates on the rock.
Husbandry: The Tosia Sea Biscuit thrives best if kept in established aquaria with live rock and a healthy sponge population. It feeds nearly exclusively on the film growing on live rock. It is very sensitive to salinity changes and should be acclimated to a home aquarium system very slowly, over 4 hours or more time.
