A few weeks ago I got an Axolotl, Achilles, who is around three months old and living in a 20 gallon tank. He has been doing really good until an abrupt change today. He floats at the top of the water at an angle and his symptoms are: • Lack in equilibrium • Swims in corners, tail up. • Low responsitivity to me touching him with a net. This is definitely not the norm. I’m worried about him. Water temp is a bit higher than ideal, so I just put a bag of ice cubes in to hopefully bring it down. Aeration has been manual on my part due to destruction of airline tubing by other pets. (I’ve been sloshing around the water with my hands multiple times a day in short segments to remove the film on the water and make it not stagnant). I also just reduced the water level to about half full since I heard that helps. Pls refer me to someone who can help. Also sorry for poor details, I’m rather urgent (and will do about anything).
