I have a fiddler/red claw crab tank set up. 10 gallon beachside biotope. Whatever petsmart has will determine which species I get. Anyway, after researching for a few weeks I have yet to see or read about the crabs burrowing in a tank. I know they do in the wild. Does anybody know if they will naturally burrow in a sand substrate?
