I currently have a male fiddler crab (Lefty) and a 55 freshwater tank. there's no way for him to get to the surface for air and he needs brackish water anyway. If anyone could offer him a good happy home that would be awesome. I don't have any living thing in my tank as of yet (it's new) and would be very willing to take anything in exchange for Lefty but I would also be happy to donate him to anyone who is able to take proper care of him.
