Red Devil Freshwater Crab Reg
The Red Devil Crabs reach about one inch, and about 2″-2.5″ with spread legs, (smaller than Mini Fiddler Crabs). They have two small claws that are uniform in size. The claws do not open very wide and are NOT able to pinch you! They are not aggressive with each other or anything similar in size. A half a dozen crabs will happily reside in a 5 gallon tank.
