What is this ?!?!

[Reef2187]

Does anyone know what this is??? It is in the bottom of one of my rocks.

Also, I have some bryopsis growing in my tank. I have seen people treat it with fluconazole. But how do I get it with out a prescription?

Some sort of sponge I think.. it's a good thing..

Black sponge.

If it's a sponge will it live now that it's been exposed to air?

It might, it depends on how wet it stayed out of the water. As a general rule you shouldn't expose them to air. Air gets caught up in the tissue and they suffocate.
