Lighting is important for small tanks as it is for big tanks. Having the right lighting not only helps to grow healthy and vibrant plants but also make the colors of your tank pop.

For a small tank, finding the right lighting can be an uphill task. If the light is too strong, you will have an algae problem, and if the intensity is too low, the plants will suffer a slow death. You also have to contend with the lack of space to install the lighting fixture.

This is where clip-on LED lights come in handy. To make it easy for you to find the perfect light for your small tank, here are reviews of four excellent options for small and nano aquariums.
