Swollen anal fin? (Senegal bichir)

[Yuu]

Hello! My senegal bichir has had that lump for a few months now. I don't have the funds to afford bring it to the fish vet as it could cost up to $100 inclusive of the consultation fee here in Singapore. Please tell me if there's anything I can do to help my bichir, I really don't want my bichir to die

Anything small in ur tank it could swallow? Would try a round of kanamycin or maracyn2. Hold feedings for a bit.

This happens to male bichirs when there are no ready females present to spawn with.
I don't believe that it will kill your bichir, but it may make it more aggressive in the future.
Josh's Fish knows more about this than me.
