I have 1 juvenile axolotl in a 20g tank. He was recently floating so i tubbed him and put him in the fridge, he stopped floating and seemed pretty happy. This afternoon however he started floating again. I know axolotls just float randomly but is this something I should be worried about? He is trying to swim to the bottom but can't. I also havent seen any poop recently so is that a bad sign? The stress he brings me annoys me so much because I love him but I don't know why he keeps floating.
