Friend or Foe

how about "big"?i keep everything in the tank till i see damage being done. no damage id keep him in. a clue is weather or not there is serated claws, if so its a meat eater if not then dont worry

get rid if it.

Whoa!
Crabs with either serrated claws or red eyes are evil predatory mongrels... and yours has both...
I vote for trigger food on that guy

Grow him out in the sump and boil him with some Ole Bay.... :beer:

Is it gone yet?

I think I missed my opportunity. Can find him anywhere. I used to know where he was hinding out and I figured he would go back there. Now he is missing. Regardless, he is so hard to catch, because he moves so fast.
