I'd be more worried about the fish. The crab will eat anything it can reach.
Plus a fiddler crab needs access to land, and fiddler (and most crabs) are brackish water animals, and even if they can survive in fresh water for short times, you'd probably end up with a lot of problems in the end.
taking a break from fish-keeping.
3 lovely male betta still keep me company.
