Please help ID - aiptasia?

[kimts]

I found two new things growing in my tank today, and I’m hoping y’all can help ID. One is growing out of some zoas and the other is on the rock. I’m not even sure they are the same thing. Anyway, if aiptasia, what is the best way to remove from 15 gallon tank? Peppermint shrimp?

top right and bottom left looks like some sort of algae, bottom right looks like aiptasia. can't really tell on other 1. If the problem isn't widespread, spot treatment works really well. AiptasiaX always does the trick for me: https://amzn.to/4d3o3XH

Last photo looks like it. I just found one as well. I don’t touch it so it doesn’t spread.
