It's not MBD, he has short tongue disorder. It's a lack of Vitamin A so You want to get Repashy Supervite. Back off on the calcium, native toads don't need as much as frogs do. Toads also need their vivs on teh dryer side, they DON"T like it wet and humid unless you're breeding them. I feed my toads twice a week and alternate between the repashy calcium and the supervite. Also your toad doesn't need special lighting either. I don't use CFL or fluorescent either, only LED.
