Can someone identify this zoa

[Charlie brown]

I picked this rock up at my lfs store and these started popping up out of no where I'm worried they might be nuisance zoas

Yeah they look like Texas trash palys

Should I get rid of them don't really want undesirable zoas over running my rock

If you can just break of the peice of rock they're on put it on the sand bed. That way you get free coral without it taking over your whole tank

Get rid of them, they’re a nuisance
