What is it?

Hi, any idea what this could be? I have noticed 3 in the same space. The biggest one is open and the other 2 are something like white bubbles. They are on a live rock

The tank is running for about 2 months now.

Almost looks like some type of paly. Not too sure. @KJ @Lovemyreef2015 any ideas?

Paly's that were dormat, coming to life again. I had some that started this way and grew out of control. Since there's a good chance these will do the same over time and most likely contain toxins, I'd suggest killing them in the display one at a time.

Yep it's a palythoa/ protopalythoa

If their just on that one rock take it out of the tank & leave it out side to dry out. If you try to get rid of them in the tank they could release toxins into your tank that could affect it & you. Also trying to clean in the house is not recommended. Do a search here on R2R or google & you'll get more info about them.
