You can tell a fiddler crab's gender by its claws. A female fiddler crab has two claws, the same size. A male fiddler crab has one large claw and one small claw.
There many species of this small crab, living in colonies on mudflats and tidal beaches and marshes. So called fiddler crab because the males have on claw greatly exagerrated in size, resembling a violin player holding his violin up.
It's hard to know how much a fiddler crab weighs because there are many different types. But I do know that a fiddler crab's large claw weighs about half of it's body weight.
The land hermit crab has a big claw and a small claw. The ocean hermit crab's claw's are the same size.

He crapped out a live crab while doing the Mexican hat dance, and the size of the live dump gave him an anurism.
it depends on the size of the crab
In an average medium size crab, there is about ½ cup of meat. There usually isn't a lot of meat in crabs.
i work in a pet store and i do know that Fiddler crabs eat microscopic critters that show up in the sand as well as algae. The crabs sift the sand with their claws (or claw if its a male crab) and get nourishment from the microscopic particles and bacteria in it. ...but as far as fish go, they are not the type to stalk their prey, they would rather have a wounded or weaker fish sort of drift by and then attempt to grab it. So you could possibly try some small minnows or maybe even the smaller goldfish (it all depends on the size of your crab). HOPE THIS HELPS :)
