emerald crabs should be ok, when they get larger...that might (MIGHT prolly not) atk small small fish...if it is an emerald crab i wouldnt worry about it

I had an emerald crab, ( he died of natural causes as far as I can tell) and he never harmed anything. he just traveled around the rocks harvesting algae and kept to himself. I say they're OK.

I have 3 of them. All in all a good crab to have. The big one I got away tips stuff over but nothing else with eat bubble algea so they will all way be useful.
