I tried eveyrthing. This is the second time. I don't know where his old shell is, but its gone, and a few months ago, he came out of his shell, and I put him into a dark little box with a few shells, and he put one on. This time, I gave him lots of shells in a dark box, but he wont go tino any of them, even when I left him for 5 hours there. I put him into a tank (I forced him intoo a nice good-sized, clean shell) and he came out of it, and wont put any others on, its been 3 hours, and hes not putting one on
I know its stress-ful for him, but the shells (And his tail) are clean, and there are no pests or anything in the shells. I have around 6 shells of his size, and he doesn't want any of them
Please help!
