Is It Ok To Leave Fish Tank Light On All The Time?

Fish tanks are a popular addition to many homes, and one of the most important aspects of keeping fish is ensuring that their environment is suitable. One question that many fishkeepers have is whether it is okay to leave the light on in their fish tank all the time.

There are a few things to consider when making this decision, such as the type of fish you have and the plants in your tank. If you have fish that are sensitive to light, it is best to avoid leaving the light on for extended periods of time.

Plants also need a period of darkness to grow, so if you have live plants in your tank, you will need to turn the light off for a few hours each day.

In general, it is best to have a light cycle that mimics the natural day/night cycle, with the light on for 10-12 hours each day. This will provide your fish with the necessary light to see and be active, while also giving them a period of darkness to rest.
