Can you pick up fiddler crabs?
No, Because if you do they lose a leg. But if you pick up a male they will lose a leg and a claw but the claw will grow back not the legs
No, Hermit Crabs and Fiddler crabs require two different environments. The Hermit Crab would drown in the water a Fiddler Crab needs. You can always ask your local pet store if there is any way possible though. Some hermit crabs live on land others live in water even land hermit need two enter salt water , fiddler crabs are brackish or fresh hermit crabs can't breathe in those environments
