So I recently bought 2 babies about 2 weeks ago they was fine for the first few days then I noticed one was shedding and the other was nipping at his back. I wasn’t sure if he was trying to get the shed skin or if he was being mean I left it at that but payed more attention when one morning I seen him bite his tail so I instantly separated them. The one that was biting is totally fine, I noticed growth in him quickly! However the one shedding seems down, he just stays on the bottom laying there I try to encourage him but nothing. I’m not sure if it’s because he’s shedding still or is it because I moved him?
