Re: Tail srinking
Have you tested the water for Ammonia, Nitrite, Nitrate, and pH levels? The most important tests are for Ammonia and Nitrite (both are highly toxic).
What's the water temperature?
How large is the tank? (length x width x depth)
...and does the axolotl have any tankmates? (other axolotls, or feeder fish, etc).
Are you doing daily partial water changes? How often, and how much water do you replace each time?
What do you feed the axolotl? Are you cleaning the left over food out promptly after each feeding.
A little more information will help light our way. :happy: Please provide as much information as you can, to help us to help you.
