Mouth rot? Mouth fungus? Ulcer? How to treat?

[Don90]

Hi all, my betta has this growth on the mouth 2 days ago.

I have dosed API fungus cure, but there hasnt been any significant change...







Is this mouth rot or mouth fungus? or is it an ulcer?

I'm thinking if using waterlife myxazin, but is it effective?

looks like fungus i think.
treatments for fungus are mostly based on methylene blue and other salts. not sure what medications there are in singapore. good luck!

This condition is very common in bettas. What I use is a combo of coppersafe and yellow powder (nifurpirinol). Change water first before you start dosing.
Always works like a charm.
