Wierd White Lump

HI all,
I have my betta fish for 2 years now and couple of months ago I have noticed a white lump on his lower fin. It started as a smaller lump but now it is quite big. I treated him with betta fix since I read online that might be a fungal infection. But the treatment didn’t work. The lump just got bigger. If anyone knows what is it or how to treat this please let me know.
Thank you
Ivan

 

Fungal infections look fuzzy. It appears to be fuzzy then betta fix and melafix will not work because those only help the Slime coat add prevent bacterial infections. If you still think it's fungal you should try Prima fix if you want to go with a natural remedy.

 

I have posted the img below so you can see how it looks. If its fungal what should I use? Just primal fix?

 

Primafix is the natural herbal remedy. Idk what is the stronger option

 

Ok I’ll try that. Thanks

You could try API fungal cure, maricin oxy, or kanaplex/kanamycin. Many medications with an active ingredient with “fur” in the name would work
