Question: What's wrong with my axolotl

[ShadeFx]

The tips of my axolotls gills have started going white, does anyone know what this is?
Worried that he may be getting sick

If it's not fuzzy, then it's nothing to worry about. The gills don't have oxygen in the tips, because the axolotl doesn't need its gills to grow bigger. If there's plenty of oxygen in the water, the gills might even grow shorter.

However! I can't see it too clearly in your picture, but I think the white tips are fuzzy?
Then it's fungus and you need to treat your axolotl for it.
So... fuzzy or not?

Could you tell us what your water readings are for Ammonia, Nitrate and Nitrogen? It is possible there is something off with the water quality.
