My mother got one of those vases with a beautiful red betta. The plant didn't look so good after a few weeks, so she took it out and put black opalescent glass marbles in the bottom of the vase. My father does a water change, I'm not sure of the specifics but I assume it is a 25% water change, every week. I'm not sure how frequently he cleans the marbles. I should ask him about that.
She's had that betta for a long time now. He swims around a little, and looks very healthy. If you sit near the vase he flares and shows off for you for a few minutes.
