I was at petsmart and was looking at the bettas and an otherwise gorgeous halfmoon betta had most of its tail bitten off! (I'm guessing it might've had something to do with the overly aggressive betta next to his cup) I told an employee and he said that he thought the tail was supposed to be like that. I said ot wasn't and pointed at another halfmoon who had all his fins and told him that was what it was supposed to look like. So Mr."smart"employee said that he didn't get how he could've bitten of his fins when he was alone in his cup.
Then he just took the betta away to who knows where. (I'm suspecting it wasn't a good place) I am so mad at petsmart!!!!!!
