Do Guppy Fish Sleep: Interesting Facts That You Need to Know

It’s no secret that guppy fish are popular pets. Not only do they make great companions, but they also make beautiful decorations inside your aquarium.

Yes, guppy fish sleep in the same way that other fish do, although it might be difficult to notice because they sleep with their eyes open. Some people believe that guppy fish need to sleep because they are constantly swimming and eating. However, other experts say that the fish sleep more than most other creatures because there is little danger in their environment.

How Much Sleep Do Guppies Need?

Guppies are usually very active fish and need a lot of sleep. There is no one answer to this question since guppy fish vary in their sleep habits and needs. However, most experts believe that guppy fish need about 6 to 8 hours of sleep per day in a tank with adequate water conditions. This is a normal part of the fish’s life cycle, which helps them to rest up for when they need to feed.

If your guppy is not getting enough sleep, it may become tired and lazy which could lead to illnesses or even death. In addition, if your guppy is not getting enough sleep, it may be more susceptible to disease.

How Do Guppies Sleep?

Most guppy fish sleep in a similar way to other fish. They swim around and maintain their composure even when they are sleeping with their eyes open. This is because guppies do not have any dorsal or anal fins which would make it difficult for them to stay still while they sleep. Like other fish, guppy fish sleep by moving their bodies in a rhythmic motion. These movements are so small that it’s hard to notice, but they help the fish to stay warm and calm.

When Do Guppies Sleep?

Most guppies will fall asleep during the night. If your guppy is not getting enough sleep, it may be displayed by abnormal behaviors such as being more active at night or swimming close to the surface of the water.

What Are the Signs That My Guppy Needs More Sleep?

If you notice that your guppy fish is not getting enough sleep, there are some signs to look for. One sign may be increased activity at night or a decrease in appetite. Other signs may include lazy behavior, difficulty staying still during trips outside of the tank, and reduced swimming speed. If you see any of these signs, it’s important to take your guppy to the vet for a check-up so that it can get the appropriate amount of sleep.

But before you do so, there are things that you can do to ensure that you are doing your best part to help your guppies sleep better.

How to Help Your Guppies Sleep Better

If you want to help your guppies sleep better, it’s important to keep their tank clean and organized. In addition, make sure that the water in the aquarium is changed every day. Doing this will help to prevent diseases from spreading, which can be fatal for guppy fish.


You can help your guppy get the sleep it needs by keeping its tank at a temperature of 75 degrees Fahrenheit and providing a lot of hiding places for it to rest in. If you are using aquarium gravel, make sure that there are no sharp edges on the rocks so that your guppy cannot accidentally injure itself.


Aquarium lighting needs vary depending on the fish species, but most guppies need low light while they sleep. If you want to help your guppies sleep better, it’s important to use a bright moonlight-type fixture that emits only a few watts of light. You can also set up an aquarium with background lights that are turned off during the hours when your guppies are sleeping. Guppies need light to survive, but unlike other fish species, they aren’t very concerned about the amount of light that they receive. As long as there is enough natural light coming into their tank, guppies will be just fine.

Hiding Spots

Guppies will use any hiding place that is available to them when they are sleeping. This can include the bottom of the aquarium, under rocks, or even in small crevices near the water’s surface. It is important to keep an eye on your guppies when they are sleeping, as they may escape if they see that you aren’t paying attention.


If you want to help your guppies sleep better, it is important to choose a tank mate that will not disturb them. Some tank mates that are suited for guppy fish include tetras and smaller catfish. Try to find a fish that is similar in size and behavior so that the two species can peacefully coexist.

Some of the best tankmates for guppies include tetras, smaller catfish, and hippo cichlids.

Aquarium Space

Guppies need plenty of space when they are sleeping. If the tank is too small, they may try to sleep in other areas of the aquarium or even on top of rocks. Make sure that you have at least 2 gallons per guppy to provide them with enough room to stretch out and relax.

Water Parameters

Guppy fish need water that is clean and free of chemicals or other pollutants. If you are using a biological filtration system, be sure to run it when your guppies are sleeping to keep the tank clean. In addition, make sure that the walls of the aquarium are smooth so that guppies have plenty of places to hide and sleep.

How Do You Know If Your Guppy Is Sleeping Or Dead?

If your guppy isn’t eating or appears to be inactive, it is probably sleeping. However, you can sometimes tell if a guppy is dead by gently tapping its body and watching for a response. If there is no response, the fish may be deceased. Guppies are active fish and will usually be moving around the tank frequently. If your guppy isn’t moving, it is probably asleep and may need to be woken up if you want to see it alive again.

Moreover, if you are trying to determine if your guppy is alive or dead, you can always look at the color of its gills. If they are dark green, then it’s alive and active. If they are red or pink, then they may be dead already.
