This makes me sad because you would think pet stores or any other kind of stores that house fish would know its mean and cruel to have any fish in a small space. Betta's have enough hard time living in cups and well I think stores shouldn't be allowed to house them like that, they just sit on a shelf and are forgotten about half the time and their water seems to be not filled or changed. Its abuse and its sad that they will tell you that your betta can live in those cups or small vase which I think is down right cruel. all the other fish get to live in tanks why can't the betta's? I hope one day that there will be a day when I go to the pet store and see betta's in fish tanks and not cups.
