What temp is the water?

The water is 77°F.

[Betta fin rot keeps getting worse]

• pH - 7.6
• Nitrates - 0-5 ppm
• Nitrite - 0 ppm
• Ammonia - 0 ppm
• Water Temperature - 77 F
• Hardness - I don't know
• KH/Buffer - I don't know

I use an API test kit. 2.6 gal planted tank with zebra nerite as well.

I've been struggling to help my betta heal from fin rot for the past couple months, and it's getting really bad. I first noticed it at the end of August. I started by trying twice weekly water changes (once every week or week and a half was my norm). Then I tried E.M. Erythromycin and finally a combo of E.M. Erythromycin and Rid-Ich.

He has some other problems, and I don't know if they are related. His right gill plate sticks out. He was like that when I got him. He also has some lumps on his sides that I noticed maybe a month before I noticed the fin problems.

Looking at the pictures now, does he look too skinny? I feed him once a day, rotating through mini pellets, flakes, and frozen mysis.

First picture is from the beginning of September. Second is from a week ago, and the others are from today.

I'm new to fishkeeping, so I don't really know what I'm doing. Please let me know if there is any other information I can give that might be helpful. Any advice is greatly appreciated.
