Do guppies sleep?

Guppies are colorful and lively aquarium pets, and understanding their sleep habits is crucial for maintaining a healthy environment. In this comprehensive article, we’ll dive deeper into the world of guppy sleep and discover the factors that affect their rest, the importance of proper lighting, and how to create an ideal sleep environment for your guppy fish.

The Need for Sleep in Guppies

First, let’s address the main question: Do guppies sleep?

  • Yes, guppies sleep!

Like all fish, guppies need to rest, though their sleep is quite different from human sleep. While resting, fish remain more alert than humans, making it difficult to determine if they’re asleep or awake without knowing the telltale signs. Sleep is essential for guppies as it allows them to conserve energy and maintain proper bodily functions.

When Do Guppies Sleep?

Now that we know guppies sleep, let’s discuss when they prefer to catch some z’s.

  • Guppies sleep at any time of day
  • They prefer to sleep in the dark, so they generally sleep at night

It’s essential to turn off your aquarium light at night, allowing your guppy fish to rest while you do the same. However, it is important to note that guppies can also take short naps during the day, especially in low-light conditions or when they feel secure.

The Importance of Proper Lighting

Proper lighting plays a crucial role in maintaining a healthy sleep cycle for guppies. A consistent day-night cycle helps regulate their internal clocks, ensuring that they get adequate rest. To achieve this:

  • Maintain a regular schedule for turning the aquarium light on and off
  • Aim for 12 hours of light and 12 hours of darkness
  • Use a timer to automate the lighting cycle, ensuring consistency

How Do Guppies Sleep?

When it comes to guppy sleep, it’s quite fascinating to understand how they do it.

  • Guppies don’t close their eyes when they sleep
  • They can’t close their eyes due to the absence of eyelids
  • Guppies either rest at the bottom of the tank or float in one place just above it
  • Guppies may change color slightly while sleeping, usually becoming paler

Creating an Ideal Sleep Environment for Guppies

To ensure your guppies get a good night’s sleep, you should create a comfortable and secure environment for them. Here are some tips to help:

  1. Provide hiding spots: Guppies feel safer when they have places to hide. Include plants, rocks, or decorations to create hiding spots in your aquarium.
  2. Maintain water quality: Clean and well-filtered water helps reduce stress, which can interfere with sleep.
  3. Keep the tank temperature stable: Sudden changes in temperature can stress guppies, disrupting their sleep. Aim for a consistent temperature of 76-80°F (24-27°C).
  4. Reduce noise and vibrations: Excessive noise or vibrations can disturb guppy sleep. Place the aquarium in a quiet area, away from sources of loud noises or vibrations.

Spotting a Sleeping Guppy

Recognizing a sleeping guppy can be a bit tricky, but there are certain signs to look for:

  • A sleeping guppy will be much less active than usual
  • Instead of swimming around, they’ll float in one spot
  • They’ll barely move, only twitching or flicking a fin to maintain stability in the water
  • Guppies usually sleep near the bottom of the tank, slightly above the base


In conclusion, guppies do sleep, but their sleep is quite different from ours. They remain alert and don’t close their eyes due to the lack of eyelids. Guppies prefer to sleep at night, so it’s essential to turn off your aquarium light for them to rest. By observing their activity levels and location within the tank, you can tell when your guppy is sleeping. Proper lighting and a comfortable environment play a significant role in ensuring that your guppies get the rest they need.To maintain your guppies’ well-being, remember to provide hiding spots, maintain water quality, keep a stable temperature, and minimize noise or vibrations. With these measures in place, your guppy fish will have a healthy sleep cycle, ensuring their overall health and happiness.
