Rock crab???????

He looks plenty evil. Has he terrorized your tank?

I dont really know, he could be fine. I have lost a few sps recentl but don't think he is to blame. I am keeping him in a bucket untill I decide.

looks like an emerald crab to me. Igot one in a chunk of love rock and he is no threat at all. In facct, he moved to a large dead chunk of decorative coral (I know, I know, it ws from the early days, before I knew better!) and has lived there very peacefully for about 6 months. Fun to watch also!
