Can anyone help identify this.

Hello, Can anyone please identify these tuses on my live rock. They have started multiplying. Is there a fish or something that help eliminate them. Thank you.

Looks like Vermetid Snails.

I'm not personally aware of any livestock that is a sure shot way to eradicate them. But there are quite a few folks that seem to have had success with certain puffers and copper band butterfly's.
