Guppies are fascinating underwater creatures who can liven up your fish tank with their vibrant colors. But, once you get guppies, the most logical question to have is whether guppies need light.

Guppies do need light to grow and live a healthy life. The amount of light that they need in a fish tank is approximately the same as they would get in their natural habitat. This means that the light needs to be kept on for about 8 to 10 hours a day and should be switched off at night.

While this explains that guppies need light, there are still a lot of questions that come up regarding guppies and light. Let’s talk about each one of them now.

How Much Amount Of Light Is Good For Guppies?

As a general rule of thumb, you should only give as much light to your guppies as they are accustomed to in their natural habitat.

When guppies live in their natural habitat, they are used to the normal day and night cycle.

They get light during the day and don’t get it at night.

So you need to mimic this behavior in your fish tank.

Make sure that you switch on the light during the day, ideally for 8 to 10 hours, and then switch it off.

That way, your guppies will get enough light to grow, and at the same time, they will be able to relax once the light is off.

It is very important that you switch off the light because guppies need to rest too.

Exposing your guppies to too much light can kill your guppies.

So give light to your guppies for only about 8 to 10 hours a day and then switch it off.

Alright! That applies to guppies in general, but what about guppy fry?

Do Guppy Fry Need Light?

Just like grown-up guppies, guppy fry also need light. They need light so that they can grow fast and lead a healthy life.

Giving light for about 8 to 10 hours a day should be sufficient for guppy fry.

Don’t expose guppy fry to too much light; otherwise, they will die just like grown-up guppies.

Make sure that you turn off the light after 8 to 10 hours.

If you are not able to switch off the light consistently every day, then get a timer for the light so that the light can auto switch off after a fixed time.

You should be able to get a light timer easily in a local store, or in Walmart or Amazon.

Using such a timer is recommended because by using it, you can be sure that your guppies won’t be exposed to too much light.

Okay! Now that you know that guppies and guppy fry both need light for a few hours a day, the next question is when you should turn on the light? Can you turn it on at night?
