I thought it was a loose polyp of zoa last night and grabbed it and glued it down. 2min later i noticed that it “moved” of the glued spot. Upon further examination, it’s a baby rock nem. My nems probably spawned or something like that in the tank and resulting in a baby rock nem. I don’t have high hope of it living because I released it right after taking the picture since I don’t plan on baby sitting in, pun intended.
