Well, Yes and no. Betta do like LIGHT to be able to distinguish night and day, they also need the warmth, but you can use a heater. betta fish do need light, but it is not good to keep a betta in direct sunlight as it may increase the temperature byy far too much. so just keep it in light at day, or get a lamp.
