Should I quarantine my Betta with mild fin rot?

My Betta has mild fin rot that has not been getting better or worse. Right now he is in a 20 gallon with other fish. I was thinking of quarantining him for a few days to a couple weeks depending if he gets better or not.

I am planning on putting him in the 5 gal with aquarium salt and of course a filter and heater. After the few days to weeks I plan on putting him back in the main 20 gal again. Is this an ok plan?

 

Assuming your parameters are good, it depends on the sort of treatment you want to pursue. Personally, once I resolved to start using salt in non-miniscule amounts, I moved my boy because I didn't want to risk hurting my plants. It also allows you to use stronger medication, if needed, without worrying about anything else in the tank. I'm not an expert by any means so take this with a grain of salt (lol), but it sounds like a solid plan to me. Just make sure the params in the quarantine tank are the same, or at least are very close to being. Anything you can do to counteract stress while he's in there should be looked into as well, such as hiding spots, betta hammocks, lower lighting, good aeration, indian almond leaves, etc.

 

For minor fin rot, I think I would leave him in his home tank, it would be less stressfull, and stress does not help with the healing process. you can add tonics like almond leaves and stress coat to the main tank. And if you really want to use salt, most fish can tolerate the small amount just as well as a betta can."1 teaspoon per gallon," What other fish do you have? salt should not be used with catfish , scaless fish, shrimp or snails.
I am not saying that your idea is bad, this is just what I would do, or at least try for a few weeks.

I have tetras, and panda corydoras. I also have live plants. This has gone on for a few weeks with lots of water changes. I also have put indian almond leaves in there.

 

Gotcha, maybe it is time to put him in the 5-gallon.
