Weird discoloration on lethargic betta! Please help!

I purchased my betta a few months ago and he has been in a heated 5 gallon, with stagnant water. I did regular water changes and have tested water samples. All came back with non-threatening results. After noticing my betta becoming more lathargic I also noticed fade white, almost gray...I'm not sure. They're not spots or patches. Just like skin discoloration along his sides and near his gills. Could this be ammonia poisoning? I just got a filter set up and have added aquarium salt after the 50% water change. His ammonia levels are 0ppm though.

The patches aren't fuzzy. I wouldn't even call them patches. More like scale discoloration. I put the filter in a few weeks ago but I believe it has been going on before the filter was placed in the tank and now I just noticed it since it's gotten larger. It's mainly on his sides and even light highlights of white in his tail. But the top of his gills have some dark white on them. There is no redness in his gills as far as I can tell because it is quite difficult to see since his colors are so dark. And my camera when I try to take a photo of him just makes him a black blob. Ugh... It's so strange though. He made a bubble nest earlier this week too. He's been eating fine. I don't know what to do.
Correct me if I am wrong, but as far as I know - ammonia burns are red.
I think the redness on his gill cover thingy and that scar like thing are caused by ammonia. The ammonia in his cup registered at an 8.0

This guy too:

Are these grey patches fuzzy? How long as your filter been running?
