Betta Fins!!

[Sweets1023]

I've a veil tail betta in a 10 gallon for about 4 months now. The tank has gravel at the bottom, silk plants, 2 java ferns, 1 piece of drift wood that I sanded down meticulously to get rid of any possible dangers, and a plastic hallow tree thing. I do weekly water changes and test the water 1-2 times a week (I get paranoid about the health of my animals). He's been doing great, very happy and healthy. Yesterday I notice a small hole in his tail fin. So I did an extra partial water change and added some Pimafix to avoid any problems with it. I looked over a couple minutes ago and where the hole was a long thin piece of his tail fin is partially ripped off and he keeps occasionally flipping out like its bothering him ( I nearly cried when I saw it, hes my little buddy). I don't know how it happened or what I should do. I know there is not a single thing in the tank that could have ripped his fins, I spent days finding the perfect, smoothed edged decor for his tank. I also tested the water again to make sure and everything is in check.

Nitrate: 10-12 ppm
Nitrite: 0 ppm
Chlorine: 0 ppm
pH: 6.8
Temp: 82 degrees

I'm really worried about him and I don't know what I should do. Any helpful feedback would be very appreciated.

Pimafix and melafix are not good for bettas. Do a water change. Keep the water clean and do extra water changes as necessary. Clean water will help your betta more than anything.

10-12 ppm Nitrates seems kinda high for a tank 4 months old. And I agree that the water changes are definitely the best way to go, maybe a tablespoon of aquarium salt if you dont already use it.
