I have a lot in my tank. I see them on the rock, glass, and refugium. I have not had any problems with them. However, couple of days ago, I saw them on a baby zoa. I don't know whether they are zoa eater or not. I have never seen that baby zoa opening again, and then it is dead.
Are they bad or good too keep?
thanks,
