Fish Fanatic
In my area, bettas are always kept in cups or small ( tinyer then the cups) vases. Petsupermarket has the smallest cups ive ever seen in my life, about 3 inches high and 2 wide, AND have no air holes. Petco keeps there bettas in better cups there twice the size of Petsmart cups. Big Al's keeps the bettas in tiny vases, which in my opinion is worse, cause they are so close togather that they could jump into the vase! there are no tops. but the only store that actually treats the cups water is petsmart. Its treated with methane blue and ammo lock. it seems pretty uniform that every petstore here is SUPPOSED to change them every other day. Somehow I doubt that though. Alot of my fish that I bought had ammonia troubles. Its really sad.
