Fin rot!! Please help!

[EthanBeltramo]

This is my BETTA jack. Sorry, but this is the best image I could get. He is In a ten g community tank with two platy and a snail. I got him around August. In September, his fins were shredded to his body by a naughty tankmate. I returned the bully. While recovering, I think he caught fin rot or some other disease. If able to, please identify what is wrong and give me the best advice for a cure. Thanks!

How about your nitrites and nitrates?
A pH of 6 is kind of low. That may be your problem right there.

I had a few fish with fin rot and a low pH, so at the recommendation of my LFS I put some crushed coral in a mesh bag and put it in the filter in place of the carbon. That has helped significantly and no more fin rot to be found.

Adding different decor/substrate can alter your pH

When my angel was having fin issues I started putting a tiny dose of aquarium salt in my filter basin and dosing with seachem stress guard plus. In about a week the fins looked great and also seemed to stop some flashing my fish were doing. I actually liked it so much Ive kept up with the salt on every PWC (very small does) and use the stress guard like every few days.

So far no damage to anything and all the fish seem much better off, but its not like they are giving me thumbs up as I walk by.

Fin rot clears up with lots of Clean water. I suggest changing a few gallons several times a week.

Betas like low ph and soft water. He looks fine to me.
