I'm with ANHEL (and spell my name right!). Your fish doesn't look bad. Baloo's fins are all clamped, he's got lots of fin melt, he was bloating, not eating, not moving...Your fish still looks pretty good!
I'd stop with the treatments and get him in clean water for now.
Make sure that heater is working right (get a thermometer). Temp should be 78-82 F (74-84 is fine too, but not ideal).
Go back to regular fish food, and try a couple different kinds. Baloo used to eat pellets every day, and now he can't eat them, spits them back out.
Once he's in clean water, stop doing daily 100% changes. I honestly think I was stressing Baloo out with daily 100% changes, so I went to 100% every other day. I'm going to do one last one tonight, then go down to 50-75% or something every other day.
I understand your fish may be acting more and more different, but it might be because you are behaving more and more different. He might just need to be treated normally for him to go back to normal.
Also, GET A BETTER CAMERA. There could be a bunch of other things that he can/can't have. The clear pictures I took (with my phone btw) helped these guys point out that I had misdiagnosed baloo with velvet. Clear pictures can make a BIG difference. I just took a bunch of random ones and put them up for opinion.
Baloo changed color in a matter of days. Some fins turned red, then gold. His head went from black to green. He got skinnier, then the bloating happened a weak later.
This is a sick fish:
before pic, and this is after his behavior totally changed and he stopped eating, so even this pic is after he was sick for a week:
