When i first got my beloved betta, Sushi, he was a blue color, now it seems to be turning purpleish or reddish, but near his face its becoming black.
I don't know if there's something wrong, I've treated him with Bettafix, and he's more active now, but his color hasn't changed. the fins near his face are turning red. I'm not sure if it's fin rot or something else. Is this normal?
