This morning i woke up to find my axolotl floating and kind of proping him self up on the filter so he wouldnt sink. he didnt look good so i put him in the fridge for a while until my mom made me take him out. While he was in the fridge he floated sideways most of the time but once i put him in the tank he swam right to the bottom again and is just chillin out down there. He looks pretty normal other than his eyes are cloudy. I dont know if he has been eating because he is in with two other axolotls. He has been swiming to the surface alot to gulp air. Ive only had him for about a year but he was pretty small when i got him so hes not very old. Anyone know what could be going on with him?
