I just recently bough an Axolotl from the vet store and brought him home. When I bought him he had only little nubs where his gills should have been. I thought this was normal because he's a young and about 5 inches long. But I brought him home and he's always gulping for air and ends up making himself float His tank had good ammonia control, a filter with a mixture of zeolite and carbon. I'm currently using a cycle with him in the tank, so that the filter grows the necessary bacteria. He has an air stone running and shouldn't have to go up so much. On top of this, he hasn't eaten any food since I bought him and I starting to get worried The temperature is at a constant 23 degrees celcius. What can I do to help him?!
