My bf's biggest axolotl baby stopped eating. He went around 4 days or so w out eating and then it started floating belly up. I googled & read several posts about fridging it so we finally did. Its been in the fridge 3 days now and no improvement. My bf took him out of fridge (i told him would stress him out worse with extreme temp change). It looks like he might have a fungus on his toes. Not sure if its fungus or poop. But im not sure what to do now.... put him back in fridge or ? Any advice would help asap as we are very new to all of this
