Betta fish need light to be truly healthy, both physically and behaviorally. Just be sure that you provide them with a regular day/night cycle so they have a period of dark when they can rest.

Too much sunlight can overstimulate your betta, causing stress and agitation, as well as possibly causing feeding problems. If your betta spends too much time in darkness it could lose its color. You should avoid direct sunlight in your tank and opt for an artificial light instead.
