Question: Bloated & Upside Down Axolotl

[ems]

Hi there,
I have owned two axolotls for about 5 years. Over the last couple of months, one of them has started becoming fatter and has eaten less and less. He has now not eaten properly for a couple of weeks and is enormously fat! He has also started floating upside down over the last couple of days.

Today we have put him in the fridge as per instruction on this site. We used to have rock substrate in the tank (but took it out ages ago) and now there's nothing on the bottom. Our other axolotl is fine, and eating normally.

Any advice would be appreciated.

Thank you!

Can you offer your water conditions and pics of your axolotl? How long ago was it that you removed the rocks from your tank exactly? Maybe people here can help more with a little more info from you.
