Sick axolotl? Flattened gills.

[NatPiff]

Does anybody know any possibilities of why my axolotl, Spector, who I’ve had for two years, is suddenly deciding to have his gills flat against his head? I don’t believe it’s the water and I feed him regularly. Any guidance would be helpful. Thank you.

regarding gill placement the water should be tested as it can be a sign of water issues.
make sure there is good water oxygenation and that any sand/substrate is regularly turned over to prevent gas/debris build up.
