Unless they are blind cave fish, which have no eyes, fish need light.
You want a light om an aquarium so you can see the fish to best advantage.
It does not need to be a special aquarium light, if a room is light enough for you to move around in, it is light enough for the fish, regardless of temperature.
A weird thing may happen if the light comes from the side. Fish orientate themselves to light more than gravity. With strong side lighting they will swim tilted, sometimes almost completely on there sides.
