Commonly called a 'tiger sponge', it's actually a species of encrusting tunicate from what I understand. I've never known anyone to keep them alive in captivity. They are notoriously impossible to maintain... along with a couple other specimens in that softie tank. So nobody go out and buy these without knowing exactly what you're getting into please... they basically do NOT survive in captivity from what I understand.
I'm of course not usually one to support the importation of impossible-to-keep species like these sponges and the dendronepthea. Ching I was hoping you could elaborate on the research you did along with the precautions you're taking and efforts being made to keep these notoriously impossible species?
