I did a search and found little to nothing. I was rearranging some of my rockwork today and i noticed strang grey slimy thing. I thought it was a nudibranch at first. Then i realized that was probably impossible. Well, i found a picture on the web of something that looks almsot exactly like it. of course i didn't get a real good look at what it was in my tank cause it was on the underside of a rock and moved into creavise when i picked up the rock. But it has the same look to it at least as this thing.
Good or bad? Anyone know what these things do?
