Had this pop up in a piece of live rock I used to seed my coraline growth. I had thought all along it was a good guy, but it's beginning to get larger (it's about the diameter of a dime now). I want to be sure it's not a nasty before it gets out of control. With my early aiptasia battles, it's probably a majano or something with my luck It glows green under the blue nightime LED's, and closes up pretty often. It does not seem to retract into the rock though.
