my betta has a hole in his top fin that almost looks so perfect that it could be hole punched but its much smaller about the size of this o.is it fin rot?
I don't know for sure, but I have a betta will a uniform hole like that too. He's had it for as long as I've had him. i think finrot ususally starts at the tips, but someone correct me if I'm wrong
Ahhh same...one of my bettas has a perfect hole in one of his fins its really small and right in the middle! Hope its not bad...p.s he's always had the hole
My Moto has the same little hole on his pectoral fin , but he also had fin rot previously (just getting over it actually). I was wondering that myself.
