How long should my betta have a light on?And should it be day or night?

Answer 1

light by day dark by night.....but they look cooler at night with the light on

so for your pleasure or the fishes

you choose

Answer 2

Well it should be as it is for you i mean there is not a light on 24/7 in the sea so it would be better if you turn it off at night to go to sleep as my 5 yr old says ."my fish need to rest now and so do i so turn of the light"
