Do Betta Fish Sleep? How Long, When & Where

When you think of sleep, one of the first things that might come to mind is a bed or your bedroom. But what about fish? In this article, we’ll explore the sleeping behavior of bettas. Let’s dive in!

Do Betta Fish Sleep?

Yes, betta fish sleep just like most living creatures. They do this by closing their eyes and resting in a stationary position for several minutes at a time, rather than by sleeping deeply as humans do.

This may be surprising to hear, as many people assume that fish are constantly swimming around. In fact, the vast majority of a betta’s day is actually spent resting in one spot!

Betta fish are very light sleepers, which means that they can wake up quickly if necessary. Even a slight movement in the water will cause them to open their eyes and start swimming around. This protects them from predators both in the wild and at home. Bettas wouldn’t last very long if they slept as deeply as us!

How Long Do Betta Fish Sleep?

Betta fish tend to sleep for 8 to 14 hours per day. Like us, they get a full-length sleep during the dark hours. They also have a few naps during the daylight hours, which is why you may see your betta fish sitting still in one spot for a few minutes at a time.

Where Do Betta Fish Sleep?

Betta fish sleep in many different places, depending on their environment and mood. Some bettas will curl up in a leaf or under a rock. Others may simply rest at the bottom of their tank.

As long as your betta has a place to rest comfortably, he or she will likely sleep there. Just be sure to keep an eye on your fish during the day so you can spot any potential health problems!

When do Betta Fish Sleep?

Betta fish do most of their sleeping during the night when it’s dark. They’ll also take a few naps during the day, usually for a few minutes at a time. This is why you may see your betta fish sitting still in one spot for a few moments before swimming away.

As such, make sure your room isn’t bright when you sleep! This may be difficult if you like to keep your lights on at night, but it’s important for the health of your fish. Here’s more information about betta light requirements at night.

When it comes to sleeping with betta fish in a tank by your bedside, make sure there are no bright lights nearby when you fall asleep. Bright lights will confuse your betta and keep him or her from sleeping.

How Do You Know if Your Betta Fish Is Sleeping?

Bettas are very light sleepers, so it’s easy to tell when they’re sleeping. Their eyes will be closed and their bodies still for several minutes at a time. This shows that the betta is resting!

You can tell the difference between a sleeping a dead betta by looking at the gills. If the fish is sleeping, you’ll see that his or her gills are moving up and down very slowly. This shows it’s still breathing!

You can also check to see if your betta fish is sleeping by gently moving the water. A sleeping betta will become active and swim away immediately, whereas a dead one won’t move at all!

If your betta is taking longer than usual breaks in between swimming around or seems more lethargic than normal, this may indicate that he or she is sick. Contact your veterinarian right away to treat any health problems before they get worse!

Is It Bad to Wake Up a Betta Fish?

Yes, it is bad to wake up a betta fish. Bettas are light sleepers and will quickly swim away if they’re disturbed while resting. If you need to clean the tank or perform any other maintenance, do so during the day when your betta can remain active.

If possible, try not to move your betta at all until he or she is awake and ready to swim around. This will reduce stress for your betta fish that needs time to rest.

What Are the Benefits of Betta Fish Sleeping?

The biggest benefit of betta fish sleeping is that it allows them to get much-needed rest. Lack of sleep can make a betta sick, so this break time is essential for their health!

Betta fish also sleep to conserve energy. When they’re awake, bettas expend a lot of energy swimming around and exploring their environment. Sleeping allows them to rest and save up some energy for later!

Sleeping also helps bettas regulate their body temperature. Bettas are ectothermic, which means they rely on the environment around them to keep warm.

Bettas love sleeping because their bodies need time to fight off infections and recover from injuries or illness. This is important for both young and old bettas.

Do Bettas Lay Down to Sleep?

Yes, bettas often lay down to sleep. This is especially common when they’re resting at the bottom of their tank. Bettas will usually curl up in a ball or rest on their side when sleeping.

Some bettas may also sleep while floating at the surface of the water. This is more common in bettas who are kept in a tank with a lot of plants or other decorations.

It’s important to note that bettas can sleep in any position, so don’t worry if your fish isn’t following the typical “sleeping” behavior!


In conclusion, yes, betta fish sleep! They usually do this by closing their eyes and resting in a stationary position for several minutes at a time.

Betta fish typically sleep for around eight to fourteen hours per day and will rest in many different places depending on their environment and mood. You can usually tell if your betta fish is sleeping by looking at its gills and seeing if it’s still breathing.
