Thanks Gary..I did a quick search and I think you just might be right
I can't find much information on it yet (for a laymen anyway lol) but I still have a lot of pages to go tho..when I find more info I'll post it here.
It's an odd little thing and it's kinda cool in it's own way, I can understand how you would look at the ones on the rock seems like everyone asks about pests..it would be nice if this guys a keeper, it might be happier in my main tank.
