Yes. Aquarium fishes need light for a number of reasons. First, the fish need light so they can see their environment and other fishes. In addition to being able to see their environment, the fish also need light so they can move through the water column easily. Second, fish use photosynthesis from plants in order to create nutrients and oxygen for themselves and other organisms that live in an aquarium. Third, fish use light as a source of energy, and as such, certain types of fish require different intensities and spectrums of light in order to function appropriately.
Fourth, plants also need photosynthesis in order to grow and survive. Plants provide an aquarium with many benefits that range from waste processing to increased oxygen levels for the environment, and they also provide food for the fish.

But there are many different types of lights that people can use with an aquarium including fluorescent lights; high-intensity metal halide lamps; red night light; black night light (helps with algae growth); ultraviolet (UV) filters (which can help prevent infection); and blue night light. All these lights have an effect on the fish that live in the aquariums, as well as plants that live there.
Fluorescent lights give off a low amount of heat and provide very little wattage which is useful for small aquariums or ones that house “cold-water” species (e.g., goldfish). High-intensity metal halide lamps give more wattage, but they also generate more heat; this lamp is good for larger aquariums with tropical species (e.g., swordtails). The red night light can be used at night time to make it easier for people to see inside their aquarium without disturbing the fishes’ circadian rhythms (internal body clock).
