Bettas, like all fish, do sleep, but they sleep very differently from humans and other mammals. Bettas are known for their vibrant colours and flamboyant tails and fins, but when they sleep, their colours may appear slightly duller. Bettas do not have eyelids, so their eyes remain open when they sleep, and they continue to breathe through their mouths and gills, although more slowly than when they are awake. They may sleep on a large, flat leaf, a flat rock, or a tank accessory, or they may wedge themselves into a crevice or cave. Bettas are very lazy fish, and they require long rest periods to conserve energy for their long, ornate fins.

What You'll Learn
Bettas sleep with their eyes open
Bettas are very lazy fish and require long rest periods. They are known to sleep with their eyes open, as they do not have eyelids. Bettas are also light sleepers, and the slightest sound can wake them up. They are territorial and constantly on alert, which can cause them to sleep more than usual.
Bettas sleep in various positions, such as on large, flat leaves, at the bottom of the aquarium, or on a flat rock. Some bettas prefer to sleep near the surface, remaining motionless, while others may hide in decorations or lay on their sides. They may also sleep during the day, which can be concerning for new owners. However, this is normal behaviour for bettas.
To identify if your betta is sleeping, you can observe its gills and mouth, which will still be moving slowly during sleep. Additionally, the colours of a betta fish may appear slightly duller when they are asleep. It is important to note that sleeping bettas may resemble dying fish, but healthy bettas will perk up quickly.
To ensure your betta is getting adequate rest, provide a suitable environment with hiding spots and optimal water temperature. Bettas require warm water, typically around 78-82°F (25-28°C), and their aquarium should be equipped with a heater. Maintaining their preferred light-dark cycle is also crucial for their well-being.

They breathe slowly while sleeping
Bettas are very lazy fish and require long rest periods. They breathe slowly while sleeping. Their breathing motions will be much slower than when they are awake, but they will still be observable. You should be able to notice your betta drawing water in through its mouth and out through its gills.
Betta fish sleep in various positions. Some bettas prefer to sleep near the surface, sitting motionless, while others find a recluse in decorations or by laying on the bottom of the aquarium in an L-shape. Some will look lifeless, lying on their side. Bettas like to sleep on large, flat leaves or on a flat rock or tank accessory. They may also wedge themselves in a crevice or a cave.
It can be hard to tell if a betta is sleeping because they do not have eyelids. To determine whether your betta is sleeping or dead, look at its gills and mouth. Dead fish do not breathe. You can also observe its overall colour, shine, and vibrancy. The colours of a betta fish may appear slightly duller when they are asleep.
Bettas are light sleepers, and the slightest sound can wake them up. They are also territorial and aggressive towards one another, so it is important to give them enough space in the aquarium. If your betta is sleeping more than usual, check the water temperature, as bettas need warm water. Their aquarium will require a heater to keep the water at the optimal temperature of 78-82F (25-28C).

Bettas sleep during the day
Bettas are known to sleep during the day, and this is completely normal. They are considered lazy fish that require longer rest periods than many other pet fish. Their long, ornate fins take a lot of energy to pull through the water, a feature that many other pet fish do not have.
Bettas may sleep during the day because they are not getting enough sleep at night. This could be due to the temperature of the water. Bettas need warm water, and their aquarium will require a heater to maintain a tropical temperature of around 78-82F (25-28C). If the water is too cold, your betta will rest more than usual because they will have a slower metabolism. Therefore, it is important to use an in-tank thermometer to monitor the water temperature.
Another reason for daytime napping could be that they are not getting enough sleep at night due to stress. Bettas are territorial and aggressive towards one another, and excessive stress can cause illness or even death. Therefore, it is important to provide hiding spots for your betta to seek rest and feel safe. These may include large leafy artificial plants (silk only), driftwood, decorative houses, hammocks, and real plants.
Additionally, the presence of other fish in the tank could be causing stress to your betta and disrupting their sleep. Bettas should not be kept with other bettas as they are very territorial and will flare at each other. If you have other fish in the tank, they may be bothering your betta, causing it to seek refuge during the day.
Finally, the quality of your betta's food could be a factor. If their food is older than 6 months, the vitamin C content has severely diminished, and they may not be getting the nutrients they need. This could cause them to feel lethargic and sleep more during the day.

They sleep on leaves or at the bottom of the tank
Bettas are some of the most vibrant and colourful fish species. So, it may come as a surprise that they can look dull when they sleep. One way to tell if your betta fish is sleeping is by looking at its colour, shine, and vibrancy. The colours of a betta fish may appear slightly duller when they are asleep. While this change is typically subtle, it is noticeable.
Betta fish sleep on large, flat leaves or at the bottom of the aquarium. While they prefer leafy resting spots, they might also sleep on a flat rock or tank accessory. Bettas really like to sleep in large, flat leaves, such as stick-on betta leaf hammocks, which are available at most pet stores. Bettas without leafy décor may find a spot on top of a flat rock or even on the bottom of the aquarium substrate.
Betta fish specifically use this time of suspended animation to conserve their energy and allow their bodies to rest. They require periods of restful sleep to maintain their overall health and well-being. Sleeping also allows their bodies to repair and regenerate any damaged or old tissues. Besides that, resting also helps them process information from their environment and maintain a balanced internal state.
If you have noticed an increase in your betta's sleeping time, the first thing to check is the water temperature. Bettas need warm water, and their aquarium will require a heater. The optimal temperature for bettas is a tropical temperature around 78-82F (25-28C). If the water is too cold, your betta will rest more than usual because they will have a slower metabolism.

Bettas need sleep to repair and regenerate tissues and maintain a balanced internal state (increased sleep could indicate poor health or cold water)
Bettas, like all fish, require periods of rest. They enter a state of "suspended animation" during these periods, which helps them conserve energy and rest their bodies. Bettas need this time to repair and regenerate tissues, maintain a balanced internal state, and process information from their environment.
Bettas do not have eyelids, so it can be challenging to determine if they are sleeping or not. However, you can observe their breathing patterns to check—even when sleeping, bettas will draw water in through their mouths and expel it through their gills, although these movements will be slower than when they are awake. Bettas also tend to sleep at night, so turning off the tank and room lights can help establish a healthy light-dark cycle.
Bettas have unique sleeping positions. Some prefer to sleep near the surface, remaining motionless, while others seek out decorations or plants to rest on or lay at the bottom of the tank in an L-shape. They may also lay on their sides, appearing lifeless. Bettas are territorial and constantly alert, so providing hiding spots and a comfortable resting spot, such as a hammock, can help reduce their stress levels.
While there is no 'perfect' amount of sleep for a betta, observing your fish over a few weeks will help you understand its normal sleeping schedule. If your betta starts sleeping more than usual, it could indicate a problem with its health or the tank environment. Increased sleep may be a sign of poor health or old age, or cold water temperature. Therefore, it is essential to maintain the proper water temperature for your betta's specific species and ensure the tank is optimized for their needs.
