hi ^^
ok this sounds alot like what my axolotl has...
is it like a white cottonish type thing, and does it sort of hang off your axie?
a picture would help, maybe try putting one on...
if it is, its most likely fungus, caused by stress...
atm my axolotl is going through a similar thing, so ive just started to treat her, shes got what appears to be skin shedding (but its not, its just a layer of fungus) and shes also got some in her gills.
so what ive done is every day 3 times a day, i put her in a salt bath, 2tsp of salt per L, and 1 tenth of a tsp of hardness (de oxygenating stuff) into a small container, then place her in it for about 10-15 mins.
After that i put her in a slightly bigger container, with water ager and conditioner in it, and put it in the fridge. This slows down her metabolism, and calms her down alot.
if you do decide to do the salt bath, i suggest to keep doing it until a week after the fungus has cleared.
(if you dont think its too severe try testing ur ammonia, and pH, nitrite and nitrate and temperature) if these arnt what they are supposed to be, then they can contribute to stress... ESPECIALLY temperature (nothing above 20c)
GOOD LUCK...
put up a photo so you can get a more accurate response...
