Slime Coat Peeling

I noticed yesterday that my axie had small little whiteish substance around small areas of his body. I decided to leave him alone overnight to see if it was just little scrapes (he loves to shove himself into the tiniest crevices even though I do everything I can to minimize them).

He seems completely unbothered by them, and isn’t acting lethargic or anything.

Water parameters are 0 ammonia, 0 nitrites, and 5-10 nitrates. Hard water and PH around 6.7. No chlorine either.

We had a necessary house repair in an upstairs bathroom that finished about a week and a half ago (mold and water damage 🥲🥲). So the noise stressed him out inevitably, and this might be fallout from that. There have been no changes at all made to his tank besides normal maintenance and such.

There’s nothing else living in the tank besides a couple plants (with no hitchhikers), so he should be safe while the coat is healing.

I’m ordering Indian almond leaves to place in the tank to see if those help at all, but I’d love to hear your thoughts.

Any tips to help him regrow the slime coat?

EDIT: just for clarification, I sincerely doubt it’s a CO2 buildup or Oxygen deprivation causing any stress. I have two air stones and also two filters that cause good surface disturbance (nothing he hasn’t had for months), and I have a few live plants so he should be okay there. I’m full of anxiety so I try to consider any and all possible culprits lol.

Also, every tank product I use is vet approved. I’m very close with our exotic vet and have asked him many questions to make sure my little guy is safe.
