All tropical fish need light, as they tend to live near the surface around coral reefs. It is no different if the fish is kept in a tropical fish tank. Too much light duration will result in excessive algae growth in a fish tank. Therefore, light duration should be regulated to keep algae growth to a minimum.
No, angelfish do not have lights on their heads.
Anything that's bigger than them. My angelfish is afraid of the light over the tank.
