I had come home after work and my little girl axolotl was covered with a white cotton substance, which she wasn't covered with when I had left. I don't know if it's ick or a fungal infection. Right now I have her in the fridge, what temp should the fridge be at? Right now her water in the fridge is 40F and I don't know if that's to cold or if its OK. I'm also doing a salt soak for 10 min a day every day. I was wondering if there was anything else I should do? She's started to get lesions and it looks like what ever this is is getting worse. She cannot move the gill stalks on 1/2 her head.
