Axolotl stopped eating

[LuigiB]

One of my Axolotls recently stopped eating and I'm getting worried. After we returned from Holiday 2 weeks back, temperature was on the high end (+/- 24 Celsius), but the last 2 weeks I've kept it stable on +/- 20 degrees with a JBL cooler and frozen water bottles . Quality of the water is ok. Unfortunately, one of my axolotlts refuses to eat. In the beginning she (or he?) was still trying to and took the pellets and earth worms, but she always spat it out immediately. Now she even doesn't try to eat it. If I put a worm in front of her, she just turns around and swims away. This is now almost ongoing for 2 weeks, so I'm getting really worried about her. I don't see anything abnormal on her, so I don't really have any idea what is wrong.

Currently thinking of isolating her and putting her in the cellar where I will easily be able to get a stable water temperature of 18 degrees.

Any idea what might be wrong? Does somebody recognizes some sign of disease/stress/... on the pictures? Is isolating her with a daily water change a good idea?

her gills are nice and red so there's plenty of oxygen and there's no sign of anaemia, there's no hook/kink in tail or overly forwardly facing gills neither is her back raised so no outward signs of stress, the redness leads me to think it could be heat related.

It's possible that 20C is a little too warm for her sensitivities so your idea to move her seems a good idea.
