Illness/Sickness: Floating axolotl but its not normal floating

I got a juvenile axolotl in late august from a breeder at a reptile show and she has done fine until 3 weeks ago. She started to float(which I'm aware is normal) but it didn't stop. I tried everything and shed get better for like a day but then it'd come right back. At this point she floats only by one side, its distended slightly and shes usually so high up her legs on that side are sticking out of the water. I've tried fridging, water change, putting her in a small isolation tank, no filter no substrate. I put her in just enough water to cover her so shes not floating too much. tried starving her and feeding her but she poops and eats just fine. I thought she might have eaten gravel before but shes pooping so i feel like that's not the problem. Any ideas what could be bothering it and what i can do to help?

Can you post a picture and explain what your water temp and parameters are?

The standard treatment for constipation or impaction related floating is fridging and low water, but if you've tried that we'll have to think again.

What are you feeding her? I'm going to suggest feeding her maggots or waxworms - they are fatty and can help ease the 'blockage' through the digestive system. They can pass gravel for months after they've eaten it - without getting too graphic the mouth is bigger than the bum and she may not be able to poop it out until she gets a bit bigger.
But if she's not having trouble eating and pooping it may be something else completely.

I also have to ask which side she is floating on - if it's the left uppermost she could have problems with her liver and would need to see a specialist vet.

The temperature has stayed around low 70's, I've been putting a big hunk of ice in there at least once a day to try and chill her a bit.
I'm feeding her the axolotl pellets the breeder gave me, tried feeding her blood worms once but she wasn't really interested. Will definitely try maggots though.

It is the left side, sometimes middle sometimes more near the rear but I'm going to watch it more now that you brought it up. What might have caused liver issues? Just wondering if it is something i did or breeding issues ect...

will post a picture in a sec
