So i dont even know where to start for a search on this. I know its an algae grazer. Like most nights before i go to bed i go tgrough make sure things are locked up and i check on my kids. I usually check out the tank then too. Usually just see my peanut worm, bunch of amphipods, and my usual bristle worm pals. Then tonight i saw this. Turned the light on as fast as i could and snapped some pictures. It is definately nocturnal as it went back into the rocks as soon as it could. Any id on this sucker?
