Have you tested the water?

I know one of the first thigs they will ask for on here is for you to post the results of the water test on here.

You could also tell us the following info and someone will be able to help you.

Tank size?

Stocking?

Was the tank fully cycled?

When you say '2 fighters' was this male fighters? female fighters?

White mouths and patches on the body sounds like columnaris. Maracyn will treat columnaris as well as any other bacterial disease. More inf can be found here.

Yes, sounds like columnaris which killed my betta recently. If you're in the US, maracyn is the stuff and I think it doesn't affect your filter bacteria. In the UK, it's myxazin which you mustn't overdose as it will affect your filter bacteria.
