Well, I think my betta is a tailbitter. Yesterday he was normal, but when I woke up today I saw his upper fin has some bloody patches. It looks like he got bored at night and started to bite himself for fun, so the fins inflamed, and now are red. I am doing 100% water changes everyday in a 1gal tank and using an anti bact and fungal medicament.
I dont think it could be finrot overnight, because there are is no black anywhere in his body, just some red at the tip of his fins.
Is this treatment I am doing fine?
