Tough to tell from the pic but looks like sponge and cyano. Is this a piece of rock you want to add to your tank?

no but i was worried that it could transfer on the back on a fish and well it looked bad to me so i thought i would ask it looked like a mold under water

It's a sponge, completely harmless and beneficial to your tank

When I buy a coral that is attached to a rock (instead of a frag plug), one of the things that helps me decide to buy one over another similar coral is the amount of freebie life that comes with it. As long as it's not covered in aiptasia or other pests, the more, the better!

+1 on sponges

While most of them are harmless, there are some species that can become invasive and smother your corals. I'm not sure if that's the case with these, but definitely keep your eye on them.

Nothing to worry about being brought in with a fish.
