I got a single turbo snail last Saturday and he has retracted into his shell. I thought this was normal because it was a new environment but he seems stuck and can't get out of his shell. I can see him trying but he can't "unfold" out of his shell. He has flipped over twice since I put him in and I fixed him once I saw it. I just let him be to see if he can figure it out himself but he can't seem to get out of his shell. What is happening? Is he going to be alright?
