Your axolotl looks fine from the photos, but as emdalliance posted, the temperature really need to come down. Some of mine developed light patches (fungal infections) due to being in 22 degree C water for an extended amount of time.
What are you doing for cooling? What I did before I finally had to give in and buy a chiller was fill multiple 2-liter bottles with water and freeze. Once frozen, I would place one bottle in the tank, and when the bottle fully thawed, I would replace with another frozen bottle. If your tank is smaller, a 1 liter bottle works fine too.
