Frag Tank Discovery

[TnFishwater98]

Can some identify these. Cleaning frag tank noticed these on side of a rock. At first when it was small I thought it was a sponge. Now that it has grown, I don’t believe it is. Zoas? Paly’s? Something else?

That appears to be the little known green aiptasia colony? If those are fast growing/ multiplying I would remove them asap.
