freshwater crabs for African Cichlid Tank?

I friend of mine had fiddler crabs with cichlids in it. They are very
cool. They would "put-up-thier-dukes" when the cichlids got to close,
very funny. They got out all the time though, even climbing up the
intake for the filter. He eventually put chickenwire over his tank.

Not surprising. Most fiddler crabs are more terrestrial than aquatic.
