Aquarium Lighting Buying Guide

One of the best parts about being an aquarist is the opportunity to build a thriving ecosystem customized to fit your aesthetic. Before installing lights, you should keep a few factors in mind, as the best choice may change based on the specific needs of your tank.

Fish Color

colorful fish

When light hits different objects, they absorb some colors and reflect others. The mirrored parts of the spectrum are the ones we see. The best aquarium lighting for fish color will intensify those reflected colors while providing adequate white-light brightness. 

So, for example, warm-colored freshwater beauties like the electric yellow lab, flowerhorn cichlids, and cherry barbs will look stunning under red LEDs.

Cooler-toned Blue Gularis killifish, cobra guppies, and pygmy sunfish are a spectacle to behold under blue lights.

Plant Life

Planted aquariums have different needs than those that only house fish, as the foliage needs artificial light to photosynthesize effectively. Full-spectrum white light is your best option, providing the blue and red light that plant chloroplasts absorb to fuel food production. 

Lighting intensity, measured in lumens, also changes based on the types of plants in your tank. 

Light Level NeedsLumensExamples
Low intensity15-25 lumensVallisneria, Java fern, lemon bacopa
Medium intensity25-50 lumensAmazon sword, Brazilian pennywort, moneywort
High intensity50+ lumensDwarf hairgrass, microsword, dwarf water clover

A touch of green light can also help create contrast between your aquarium plants, though you should keep in mind that excessive amounts can make algae populations grow uncontrollably.  

Light Schedule

Fish, especially those that are exclusively nocturnal or diurnal, need regular day cycles to help regulate when they sleep, eat, and explore. 

For example, cardinalfish, soldierfish, and eels are popular saltwater inhabitants who rely on moonlight to know when it’s safe to emerge from their daytime hideouts. 

If the light setup you choose doesn’t include a built-in timer, you’ll need to purchase a separate product to ensure your fish’s routine isn’t interrupted and you have a chance to enjoy watching them.

Aquarium Depth

Because water absorbs particular light, you’ll need to adjust the brightness of your white lights to compensate if you want the bottom of a particularly deep tank to look as brilliant as the top. 

Red light has an incredibly short wavelength and isn’t visible past 100 meters. While your tank certainly isn’t that deep, warmer earth tones will appear much less vibrant if the brightness of your white light isn’t strong enough to penetrate the depth of your aquarium. 

Heat Levels

The advantage of LED lights is that they produce very little heat, making it easier to maintain safe temperatures for your tank inhabitants. 

However, if you are interested in other bulb options like metal halides or fluorescents, be aware that they produce much more heat than LEDs. You’ll need to offset the increase in temperature with water chillers and keep a close watch on the thermometer. 


Finding the best aquarium lighting for fish color can be complicated, especially when there are many factors to consider. These FAQs can help clarify some key things to keep in mind. 

Does light affect fish color?

While light does not affect the actual color of your fish, it can affect how your eyes perceive them, especially in deep tanks. 

What does blue light do for a fish tank?

Blue light enhances the color of the water in your aquarium and, because it mimics the appearance of moonlight, can encourage your nocturnal tank inhabitants to come out of hiding. It also magnifies the brilliance of cool colors, like green and violet. 

What does green light in a fish tank do?

Green light is not the best choice for your aquarium, as it encourages algae growth. That being said, it can make your tank plants appear more vibrant.
