So this arc will go over some of the betta fish myths. One being that they need a “small tank”. Bettas actually need a tank that is at least 2.5 gallons. They may be able to stay alive in the smaller tank, but it isn’t the best life you can provide them. So before you go out and get a betta fish (or any other pet for that matter) be sure to do the research so you can give your fishy friend a good life 🙂
