Very nice, just saw one yesterday in our 55g holding tank, feeling around. Couldn't catch him, but looked like he was scavaging for food. He has probably been in there for 2 years, so he can't be to bad. All the corals haven't been touched.

If his claws are flat on the ends where the tiips touch each other, then it would be an algae eater. If the claws are very pointy and more like claws for ripping things, then I would flush it.

im guessin he's bad cause he hitchhiked on a live rock from my friends tank and it killed his reef lobster...

Remove all crabs are bad.:twised::twised::twised:
Crabs are opportunity scavengers it will be fine if you feed lots but when you don't what will it eat???

Are the tips of its pincers cup shaped? If so it could be a black mithrax. Which I suspect are very similar to the the green ones. Some people have no problems with green mithrax crabs while others report that they go rogue when they get big.

It does not look like that at all. Look at those huge compact claws and those harry legs not to mention those red eyes.:biggrin: :wink: its a killer for sure.......

lol thanks for all the input guys, i guess ill leave it in my sump...maybe i should feed it aswell, i dont even know what it eats. or maybe my LFS will take it

You could be right. It is hard to tell from those pictures. I thought it kind of looked like this guy here:

+1. Send him to Browntown. I have one of those little bastages in my tank right now. When I catch him, he's going flush.
