Filter or no Filter?

The topic of whether or not filters are necessary for keeping bettas has been highly debated in the fish-keeping world.Some say that filters are necessary because if their other fish need filters, then bettas should get one too.To them, not providing bettas with filters is just being lazy and not giving them the best possible care.Others believe that filters are unnecessary and even cruel to bettas because its putting the bettas in an environment that they are not accustomed to.Many bettas, especially the long-tailed varieties go through a lot of stress swimming in the current because their fins act as a sail and are pushed to wherever the current takes them. Betta owners want their bettas to feel at home by making sure there is little or no current in the aquarium, just like the bettas natural habitat in the rice paddies of Southeast Asia.
