Emerald crab question

[Aquattro]

Sam, I disagree. I think that if a crab got a good hold of a fish's tail, it could hang on and immobilize the fish. The fish's injuries did look like they could have happened thrashing on the rocks. I once had to remove a crab from th emouth of one of my triggers...it was major surgery outside of the tank!! I ended up needing to crush the claw with pliers to remove it!
