What will eat a Sponge?

[jab502]

I have some unsightly sponge growing on a rock that are preventing the expansion of an encrusting monti from growing as much as I would like. Are there any reef safe fish, snail, crab or whatever that will eat sponges? I once saw a very colorful nudibranch at the LFS that I was told had a sponge only diet but I cannot recall the name nor have I ever seen once since. Any recommendations?

angel fish love sponge.

My emperor has been completely reef safe with the exception of eating any scrap of sponge he can find. I just read an article about them that said stomach contents of wild caught angels contained 97% sponges......
