My betta Sonatina has been, for the past two days or so, more lethargic than usual. She has this one artificial plant that she had been resting on, though today I haven't noticed her on the plant for too long. However, just tonight I noticed that she won't eat her pellets. Occasionally she will swim up to it and maybe bite at it, but she won't actually eat it. I've also noticed her swimming up to the surface for air, but I'm not sure if this is more than usual...
I did a water change tonight and I tested the pH level, and it turned out to be about 7.6, which I know is a little high.
Some background information about daily routines, and then I'll fill out the form. In the morning when I wake up, I turn on her aquarium light and feed her a pellet. I feed her either around dinnertime or whenever I get home, and her light stays on until I go to bed at night. This happens every day, with the exception of a few nights when I forget to turn it off at night.

Symptoms and Treatment
How has your betta fish's appearance changed? she has a few "shiny" spots on her, but those have been there for a while now, but colors are good otherwise, and I haven't really noticed a big difference
How has your betta fish's behavior changed? see above
When did you start noticing the symptoms? 1-2 days ago
Have you started treating your fish? not really, i don't quite know what to do...
Does your fish have any history of being ill? nope
How old is your fish (approximately)? I bought her over the summer when she was just an itty bitty little thing, so I would guess about 6 months or so
I read somewhere that it might be water conditions (which doesn't really make sense because I did everything the same as before), or a disease or even maybe just stress from the water change or too much light (on one side of her she does have a very faint stress stripe, but not as dark as when I have to relocate her over school breaks).
Any thoughts? I just don't know what to do..... and I'd be eternally grateful for any help---Sonatina's the only thing getting me through an extremely difficult time.
