I got my axolotls from someone who claimed to be a breeder so it seems unlikely that they would be anything other than axolotls unless he lied in which case I need to know if I should change my aquarium setup. They lost their gills and are spending a lot of time breathing air they no longer have the fin like tail either. All these point to salamander but I just wanted to check so I don't end up killing them because of lack of water. I attached a picture below.
