Sorry guys, I don't have access to the site at work (that's why I miss out on all the good deals).
Sharn, not really sure how he does on corals, as I have him in fowlr tank. I had him temporarily in a reef tank before when I first got him, and he did hop around from rock to rock quite often. I don't recall him sitting on any corals though, but I'm sure he must've occassionaly accidently rubbed up on a few. My only concern is that he might be a bit big for your tank (unless u've upgraded from last time). Think about it and let me know. Thanks.
Matt, I'll let you know if Sharn doesn't take it. Thanks.
