My female wild axolotl , Ni Ryong, has been stressed due to water contamination. She was in a 55 gallon tank with her buddy Sa Ryong and both were sticking close to the surface three days ago. I changed the filter and cleaned the tank and checked the water afterwards but her skin was starting to peel off on her tail. She wouldn't eat and I moved her to my bucket that I use for syphoning water and made sure to keep it cold and clean while using Reptisafe to help promote her slime coat and to generally treat the water. I have well water that is definitely on the hard side so I'm not really worried about chlorine but there could be other contaminants. I also wanted to make sure she wasn't getting a fungus or bacterial infection so I've given her a NaCl bath three times over the past three days (~7min per bath) and am done with that procedure since I think it was just the pH of the water was too acidic. It's been three days since I placed her in the bucket and she seems better at the moment with no visible signs of stress (other than a small patch of skin missing on her tail). What I'm worried about now is that the membrane around her tail has shrunk and so have her gills (though not disappeared completely) which might mean that she could be starting to metamorphose (something I really don't want). Her eyes are still their normal set and haven't begun to bulge but she makes frequent attempts to gulp in air regardless of how clean the water is. I'm really, really, really hoping that the damage done is reversible and that she won't metamorphose but I need your help. Is there anything I can do to help insure this? I have access to a wide range of certain salts and chemicals being a biochem major if it requieres something that drastic (though I hope it doesn't). Thanks.
