Best way to cure fin rot?

[loveDelphine21]

Hello fellow Betta lovers,
I'm new here, and I have a quick question about my new Betta, Onyx. I bought him from my local PetSmart yesterday, and he seems to have fin rot. I've been reading about many different ways of curing this, and I just wanted to find out if one way is better than the other. Any help will be greatly appreciated.

clean water and bettafix. I am dealing with this right now. Also aquarium salt helps.

Clean water (everyday!)
Heater set on high
Aquarium salt
and high proten foods

These are all great suggestions. Good luck!
