Joshy finally flared!!!

[Zenandra]

When they rip a fin and it grows back it comes in clear at first. There is nothing else that would randomly cause a small patch of fin to turn clear. It's very common for bettas to over flare and blow a fin, maybe that's what happened to him. My boy squishy looked like swiss cheese in his old tank because it had a mirrored back and he was just contantly flaring and blowing his fins.
