Please help! I see that you had a female fighter with some sort of mouth rot. It looks like the nostrils are swollen and lips are distended. My female betta has the same thing and I don't know what to do. What did you do? Did she die? Mine looks bad and isn't accepting food. Please help me!

What are the fish on your avatar?
Are they some type of tetra?

Hi! Thanks for your help today
