i have given him steam baths which got him to crack his eye open but close it immediately thereafter. he just started closing his eyes a few days ago and wont open them. he will navigate his tank with his eyes closed and fall off of branches and hit the ground and still keep his eyes closed. i put him in a shorter tank to limit the distance of his falls. should i return this little newbie to the breeder or should i give the little fella some more tlc and hope he comes out of it. also what are the causes of this problem.
