I cleaned Sparkle's tank (vac and water change) on 9/17 and shortly after, he started spitting food back out. Then he stopped eating. I have never figured out why, but three weeks later, Sparkle isn't looking good. He hangs out either at the top or the bottom of the tank, doesn't even look at food, and is lethargic.
A week ago, I noticed it looks like his lip may have torn somehow. It looks like there is a tear across the bridge of his nose and his mouth is no longer upward facing. After I noticed it, I posted here but got no response, so I went ahead and have started him on aquarium salt to help heal. I put 1.5 tsp in 1 gal of water and have done daily water changes since last Wednesday, always removing 1 gal and replacing with 1 salted gallon. The wound looks healed.
I am posting a pic. Is this fish doomed because his mouth is no longer in the right position to get food? I've tried garlic-infused pellets, but not much else because he isn't even looking to eat.
I have answered these questions in other posts so many times that here's the short version.

What temperature is your tank? 76
Does your tank have a filter
Does your tank have an air stone or other type of aeration? No
Is your tank heated? Yes
What tank mates does your betta fish live with? None
pH: 8.2 (same as tap water, he's been fine)
Hardness: unk, but tap water is softened
Any thoughts or ideas?
