I’ve had this blue cray in my 60 gallon for a month and he’s molted twice, always super active & hungry. He just molted on Sunday and was perfectly healthy before that. Now he’s acting strange and keeps putting himself on his back. (Still alive and moving) but he won’t eat or anything. Is this normal behavior after a molt? I have hard water & his molt looked perfect so I don’t think it was a molting issue.
