That's all good and well and well done to your parents, but i can't help but feel that them buying the fish is going towards supporting Walmart or wherever selling them. I know one sold fish is not too relevant but i read about so many of these people rescuing/saving/buying bettas from these supermarkets, even then, in the grand scheme of things all the people who have rescued bettas on here probably is not relevant, but i guess it's just my way of looking at it.
Do you have any photos of the betta? It saddens me to know that because these supermarkets buy so many fish they usually get the nicest variations in, such a waste..
I must say, supermarkets would not get away with that in the UK.
