Sponge

[daniella3d]

That's impossible as nudibranches are very specialized feeders and will only eat one type of sponge, so finding that sponge is nearly impossible in aquarium. I had a black noris living in my aquarium for many months and although it eats only sponges, it never touched any of the numerous sponges that I had in my aquarium, at least no flesh was missing from my aquarium sponges. It could have been feeding on some of them but I think it just died from starvation because it would not feed on the sponges that I had.

Beside, why buy a nudibranch only to take care of one sponge? it is much easier to simply rip it off the coral or rock if one wants it dead, that's an easy kill, no need for nudibranch.
