ID this crab

[Pier Pressure]

Well I had this emerald crab that went bad once he grew up and tried to eat all the other crabs in the tank including the hermits. I did not see it try to grab any fish but I was not taking any chances so I took him back to the LFS.

This guy is very small, Iam lucky i was able to catch him the first time.

It will be a while until he is anywhere big enough to cause any problems.

don't underestimate a small crab.
they are vicious and deadly to fish even when they are 1/2 an inch.
if they are piscevores anyway.
