Fishes aren’t exactly like plants, hence their light preference isn’t as much but they do enjoy a warm light here and then. You can use lights in your fish tank but you need to be careful about what light it is that you are choosing as they can cause excess heating in the aquarium/tank and might harm the fishes. LEDs don’t usually cause a lot of heat, but they do generate all of the heat in the upward direction. You can find various low fish tank LED light bars for your fish tank online today on Amazon, Flipkart and so on.
Various types of lights that can be used
- Incandescent lights

- LED lights
The type of LED color that generally suits fishes in the aquarium is 8000K White. The reason why this is the most preferred light color for live aquarium fishes is because, it helps in mimicking the shallow water conditions and usually is able to generate or produce higher PAE for stronger and healthier plant growth.
Aquarium fishes do not really need lights per say, but nonetheless we add it for a better effect and for seeing inside the tank clearly, so that nothing can go wrong. Since fishes don’t really need light, you can turn it off at nights as keeping the lights on throughout the whole night can cause stress to fishes, as just like us human beings fishes too need darkness to sleep. And yes, fishes sleep for all those who didn’t know.
