Guppies do sleep. While sleeping, they float at the top of the tank, on the gravel at the tank’s bottom, or near the plant decoration in the tank. Since guppies do not have eyelids, they sleep with their eyes open. You will usually find guppies sleeping at night when the lights are off.
Now, you might wonder how and when guppies sleep. Let’s take a look at their sleeping patterns and all the other details related to their sleeping.
How Do Guppies Sleep?
Guppies do not have eyelids, and so they cannot close their eyes when they are sleeping.
But then, how do you know if your guppies are sleeping?
Guppies are very active. They relentlessly swim around in the tank until they get tired.
So, when your guppies are not swimming around and are inactive, it is the time when they are sleeping and taking rest.
Guppies sleep like humans. When you turn off the lights of the aquarium, your guppies will sleep.
They will lie motionless and become inactive.
You will often see your guppies sleeping or taking rest on the gravel at the bottom of the tank.
At other times, they might float at the surface or take rest near the plant decoration in the aquarium.
When guppies are sleeping, they make no eye movements. They have a lower rate of respiratory activity while sleeping.
Guppies do not exhibit REM (Rapid Eye Movement) sleep.
They become less sensitive to sound and are not stimulated by outside noise when they sleep.
Note: If you notice your guppy floating in the tank motionless in broad daylight, it is a sign of danger. It is not sleeping, and something is bothering your little one. Moreover, if it is not eating properly, has a cloudy eye, has white spots or unusual patches on its scales, then these are all signs of your guppy being sick. A pregnant guppy does lie on the gravel during the day to rest. However, if your guppy is not pregnant, and shows any of the signs mentioned above, you need to immediately seek professional help to diagnose and provide medication.
Now that you know about the sleeping patterns of guppies, let’s understand how much sleep your guppies need for healthy growth.
How Much Sleep Do Guppies Need?
Just like humans, guppies need sleep to rest.
They need a minimum of 6 to 8 hours of sleep. They need to sleep to conserve their energy.
Guppies are diurnal fish. That means they sleep at night and are awake during the day.
Guppies do not need light when they sleep. They sleep in darkness.
Since they follow the same sleeping routine as humans, you don’t have to remind yourself to switch off the lights for them to sleep.
You can follow nature. After sunset, you can dim the aquarium light, and after sunrise, just switch on the aquarium lights.
Now, since guppies sleep for 6 to 8 hours per day, it does not mean that you need to keep the lights on for the rest of the time.
Excessive lighting will result in algae growth in your aquarium. This is harmful to the well-being of your guppies.
Keeping the lights on for 8 to 10 hours a day is sufficient to keep your guppy healthy.
Also, it will ensure that the plants in the aquarium will grow properly. It will also avoid excessive growth of algae.
Okay! Now that you know guppies need to sleep for around 8 hours, what can you do to ensure that your guppy gets the required sleep?
What Can You Do To Help Your Guppies Get Sound Sleep?
Sleep is very vital for the growth of guppies. Sound sleep helps to keep guppies healthy and free from any sickness.
So, providing a stress-free and favorable habitat to your guppies is important.
You can do the following things to help your guppies get sound sleep:
- Restful Environment: Guppies prefer to sleep at night when the sun sets and wake up in the morning when the sun rises. So, you can switch off the aquarium lights at night so that your guppies get appropriate rest.
- Hiding Places: Guppies sleep at the bottom of the tank or sometimes even float on the top of the water. You can provide them with hiding places such as plants, rocks, and other aquarium ornaments. Providing such places will make your guppies feel safe and secure in the tank and help them get sound sleep.
- Favorable Tank Condition: It is of utmost importance that you provide favorable tank conditions to your guppies as they spend their entire life in the tank. It is always advisable to keep them in an aquarium that resembles their natural habitat as it will make them feel secure. The tank should be big enough as guppies love to swim. Apart from that, water hardness and pH levels are also critical water parameters for guppies. The ideal water parameters to keep your guppies healthy are:
- Water Temperature: 72°F to 82°F (22°C to 28°C)
- Water pH: 6.8 to 7.8
- Water Hardness (dGH): 8 to 12
- Non-Aggressive Tank Mates: If you have multiple fish species in the tank, ensure that the tank mates get along with each other. Guppies are peaceful in nature, and so they do not prefer aggressive tank mates. If you have any aggressive fish along with guppies in the same tank, your guppies will be deprived of sound sleep. The aggressive fish will keep your guppies awake, either by nipping at them or bullying them throughout the night.
- Lighting: Lighting is the other most crucial factor that affects the sleeping pattern of guppies. Guppies sleep at night when there is darkness and wake up when the sun rises. So, there should be darkness around your guppies when they are sleeping. Your guppies will most likely wake up when there is any light directed towards them. That is why you need to ensure that there is no direct light facing the aquarium. There should be adequate lighting in the room where the aquarium is placed. The lighting of the aquarium is as vital as nutrition for your guppies’ health. Also, ensure that you do not expose your guppies to light for more than 10 to 12 hours a day as excessive lighting is harmful. Also, exposure to light for more than 12 hours will deprive your guppies of sleep and rest.
