How do guppies sleep? Most of us think that fish do not sleep, but they most likely perceive the world around them when they are sleeping. The difference between sleeping and waking is hard to determine for most fish species.
Many scientists think that fishes can detect day and night by sensing changes in light levels (photo periodicity).
Many studies had shown changes in general activity and response to external stimuli when the fish were exposed to light/dark cycles. The changes in behavior depending on environmental conditions such as temperature, season, habitat type, etc.
Fish exhibit periods of inactivity (e.g., “sleeping at night”) when they are not feeding or engaged in social interactions such as courtship and territoriality.
Some fish species (sharks and rays) exhibit periods of inactivity (e.g., “sleeping on the bottom during the day”) when they rest motionless on the seafloor.
Fish probably do not fall into a deep sleep as humans do but experience different states of drowsiness such as light sleep and rest.
Fish can sleep underwater as long as they can hold their breath (e.g., gar and bichir). If they are not able to breathe, the fish suffocate and die.

Do Guppies Sleep?
Yes, guppies sleep!
In a study on the sleep patterns of the guppy ( Poecilia reticulata ), another fish species from the same family as mollies and plays shown, scientists have that guppies have pronounced sleeping periods.
Placing a transparent partition in a fish tank causes part of the population to wake up while others sleep.
During the day, guppies spend more time awake, and at night they sleep more deeply. The deeper a guppy is sleeping, the less it responds to external stimuli such as sounds or movements of objects in its surroundings.
How do guppies sleep?
Guppies sleep in the dark and use an area of low light intensity (i.e., a corner) for sleeping.
The study showed that guppies could be active and responsive to their environment during the day and at night, but they spend more time asleep when it is dark. During the day, guppies sleep in the low light area, but they sleep in the dark at night.
Guppies were able to swim through holes between dividing partitions in their tanks when water was flowing gently enough, showing that guppies are not helpless if they have to swim during periods of sleep.
Guppies might have evolved this behavior because fish continuously need to monitor their environment and avoid predators.
When Do Guppies Sleep?
The study saw that fish behavior changes according to the time of day.
Guppies are most active at night – they swim more often, spend less time sleeping and reach higher speeds during their movements than during the daytime.
At nighttime, guppies become very energetic. They form social groups called shoals, swim quickly with strong undulations, and spend less time resting.
Furthermore, nocturnal fish species can exhibit activities such as mating and forage only during the night when it is dark.

When Is Guppies’ Sleep Deepest?
The study showed that guppies become more active at night (sleepless) than during the day. Scientists think that fish sleep more deeply during the day (i.e., they fall into a deeper sleep and are less responsive to their environment) because it is lighter outside, and there is more activity in their surroundings.
Fish can exhibit different behaviors at different times of the day, such as socializing only when it is dark and hiding from predators when it is light.
Fish species that hide and rest motionless during the day to avoid predators, such as sharks and rays, can be active and socialize at night.
How Many Hours do Guppies Sleep?
Fish might have evolved to sleep deeply during the day when it is light outside and be more active at night when it is dark.
Scientists suggest that fish probably spend more than half of their time asleep, just like humans.
Other factors such as body weight, sex, age, physical condition, and species can influence how much an individual sleeps.
How do you know when a guppy is sleeping?
You can tell whether a guppy is sleeping or awake by watching its behavior.
When they sleep, guppies become less active and move more slowly than when they are awake. They also spend most of their time motionless, resting in a low-light area instead of being social with other fish.
How long does guppy fish sleep?
“Guppy fish sleep for about two hours a day, but there are many variances. When guppies are in the wild, they tend to have more time sleeping because of less stress and being safer from predators.”
Do Guppies Sleep Upside Down?
Guppies sleep upside down, hanging from the surface of their tank.
Some fish might change their orientation during the night or day, suggesting that they cannot sense which way is up.
What Can You Do To Make Sure That Your Guppies Get Sound Sleep?
To keep your guppies happy and healthy, you should give them a dark place to sleep during the day. The best way to do this is by covering part of their tank with a cloth or towel.
You can also reduce the water level in your tank so that there is not as much light inside it, making it easier for your guppies to sleep.
What is a good sleeping environment for a guppy?
A dark room or aquarium is a good sleeping environment for your guppies, especially when using an overhead light.
You can also reduce the water level in your tank so that there is not as much light inside it, making it easier for your guppies to sleep.
Do Guppies sleep in light or in darkness?
Fish can exhibit different behaviors at different times of the day, such as socializing only when it is dark and hiding from predators when it is light. Do guppies sleep in light or darkness?
Guppies sleep upside down, hanging from the surface of their tank. Some fish might change their orientation during the night or day, suggesting that they cannot sense which way is up.
The Bottom Line
It’s clear that fish sleep, and since they evolved from an ancestor shared with humans sometime in the past 500 million years, it is highly likely that fish sleep in much the same way. However, there are still some things we don’t know about guppies’ sleeping habits.
