Axolotl bloated.

[AnimeDan]

Hello, my Axolotl Buddy has been bloated for about a week now. Iv had him fridged since I thought it was bloat caused by constipation. a couple days ago he finally pooped but he’s still bloated and I’m getting worried. He still moves around a bit so I know he’s alive but I’m still concerned. Should I keep him fridged? Is it something other than constipation? I’m just getting worried there might be something else wrong. His tank mate hasn’t shown any problems.
