What Happens when Aquarium Lighting Is Prolonged or Too Intense?
While aquarium lighting is beneficial to your fish, too much of it can have some adverse effects. As with anything, whatever is excessive is not good at all. Here are the adverse effects of having too intense or prolonged lighting: Stressed out dishIn their natural habitat, different types of fish are exposed to moments of day and night, especially if they are close to the surface. The hours with sunlight are spent by fish moving about. They get to rest during the darker hours. If your fish tank lighting is on all day, the fish in your aquarium do not have that day and night schedule. They cannot retreat into the dark to rest. Fortunately, this could be remedied by creating dark corners in the tank through some fish tank decor. Of course, it would be better to program the lights to turn off during certain hours.

This can also cause fish stress and may affect their health, leading to their eventual death if algae growth is not controlled.
