What are these growing on live rock?

I have more and more over last 2 months they are getting bigger. Glass animals are the bad or good? I can remove but only if they are not good for my reef tank.

Oh thank you! I just did research and found that one cell left behind can grow back so thankfully just had to remove one rock with no live stock on it. Extracted! Also found one in a larger scape piece and glued right over it to starve it out. no more pop up again.

Keep an eye out for more . Trust me. I’ve had the pop out months later from what I thought was clean rock. Recommend you get aiptasia hunters like peppermint shrimp as well.
