Betta lost a fin!

[lucky123]

I just came back from a week trip and found my betta with his top fin missing! The area where the fin is gone looks like it’s rotting. The tank parameters are: ammonia- 0, nitrite-0, nitrate-20, ph-7.8. He’s in a 10 gallon tank. What can I do to help?!

My guess would be the fin got stuck somewhere, doesn't seem like a week would be enough to rot off fully. I would be doing daily water changes at about 20% and maybe some aquarium salt to help it heal and maybe grow back.

Ok thanks!
