Bettas, also known as Siamese fighting fish, are one of the oldest species of domesticated fish. They are known for their unique sleeping habits, which can sometimes cause concern for their owners. Bettas can often be found sleeping in odd positions, such as on their side, upside down, or even vertically with their head pointing towards the bottom of the tank. They may also choose to sleep in tank ornaments, near plants, or behind the filter intake pipe. While their sleeping positions may vary, one thing remains consistent: bettas are light sleepers and will rest in short bursts throughout the day and night.

What You'll Learn
Bettas sleep in odd positions and places
Bettas are very light sleepers and will rest in short bursts. They are most active during the day and prefer to sleep at night, generally sleeping most of the night with short bursts of activity. They may also take several naps throughout the day. Bettas sleep in odd positions and places, and each individual fish will sleep in different positions and places. They might be found sleeping on their side, upside down, vertically, with their fins open, or buried in the substrate. Bettas do not have eyelids, so their eyes remain fully open even when they sleep. This can make it difficult to tell if they are sleeping or dead.
Bettas sleep wherever they feel safe. They might sleep in or on tank ornaments, next to the heater, wedged between the filter and the wall, nestled into the tank substrate, or just floating in place. They might also sleep on a leaf lying on top of the aquarium water. If aquarium plants are close to the surface of the water, they might even sleep "out of the water". Bettas are labyrinth fish and can breathe air, but they cannot do so for long and will need to stay moist.
Some bettas prefer to sleep in a hammock or on a slanted rock. If you want to provide a resting place for your betta, you can try offering different items for it to use as a bed, such as a betta log, live plants, or a leaf hammock. However, do not be offended if your betta chooses to sleep somewhere else entirely.

Bettas are light sleepers
Bettas are most active during the day and prefer to sleep at night. They may take several naps throughout the day, but they generally sleep most of the night, off and on. Bettas do not sleep like humans, but they still need to get some sleep. They rest in short bursts, and the exact amount of sleep they need is unknown. Bettas need a light/dark cycle with darkness for 50-67% of the time (12-16 hours).
Bettas sleep in odd places and positions, such as behind the filter intake pipe, in tank ornaments, near plants, on the bottom or top of the tank, or even vertically with their head pointing towards the bottom of the aquarium. They may also sleep on their side, upside down, or buried in substrate. Bettas do not have eyelids, so their eyes remain fully open when they sleep. This can make it difficult to tell if they are sleeping or dead, especially since there isn't much difference in the look of a sleeping betta and a dead one.
If you notice your betta sleeping, it is important to leave them undisturbed. They need their rest, and spooking them can cause health issues. Bettas can be startled by light, so it is recommended to turn off the aquarium lights at night to respect their circadian rhythm.

Bettas sleep more when sick
Bettas are light sleepers and rest in short bursts. They do not have eyelids, so their eyes remain fully open while they sleep. Bettas can sleep in odd positions, such as upside down, on their side, vertically, or buried in substrate. They may also sleep in or on tank ornaments, plants, or caves.
If your betta is sleeping more than usual, it could be a sign that it is sick. For example, if your betta is lying at the bottom of its tank, it may be suffering from swim bladder disease, which can cause the fish to become pale and unable to swim. In this case, you should feed them fresh boiled green peas. If your betta has a white sore on its side and is lying at the bottom of the tank, it could be due to an infection.
To ensure your betta is getting proper rest, maintain a consistent light cycle with dark periods to encourage natural sleep rhythms. Use an aquarium timer to regulate light exposure, mimicking dawn and dusk. Keep the water temperature between 78-82°F (26-28°C) and ensure the tank is clean and well-filtered. Proper conditions will help prevent stress and sickness, which can affect your betta's sleep.
If you are concerned that your betta is sleeping too much, check its eating habits and test the water parameters in your tank. If your betta is eating properly and the water parameters are fine, then it is likely just a deep sleeper. However, if you notice any other unusual behaviour or physical symptoms, it may be a sign of illness.

Bettas sleep in tank ornaments, near plants, on the bottom, near the top, and in hammocks
Bettas are known to sleep in various places, including tank ornaments, near plants, on the bottom, near the top, and in hammocks.
Some bettas like to sleep near plants, using them as a form of hammock. They may also sleep in tank ornaments or on structures such as rocks. Bettas can sleep in some strange positions, such as on their side or even upside down. While it may seem concerning to see a betta resting at the bottom of the tank, this could be a natural part of the aging process, and older bettas may prefer sleeping on the bottom. However, if the betta is exhibiting other signs of illness, such as lethargy, loss of appetite, or abnormal swimming behavior, it could indicate an underlying issue like an infection or parasite.
Betta fish are known for their vibrant colors and graceful fins, and they require a water temperature between 76-82°F (24-28°C). If the water is too warm, the fish may rest on the bottom of the tank to cool down. Overcrowding the tank can also stress betta fish, leading to submissive behaviors such as staying at the bottom. Additionally, poor water quality caused by high levels of ammonia, nitrite, or nitrate can be toxic to bettas and make them sluggish, causing them to rest at the bottom.
To provide a comfortable sleeping spot for your betta, you can purchase a betta hammock, which consists of a small leaf-shaped structure attached to a suction cup that adheres to the aquarium glass. These hammocks are usually placed near the top of the tank, but your betta may prefer it near plants or in a shaded area. Bettas occasionally nap during the day, but they will have longer sleep at night when the lights are off.

Bettas sleep with their eyes open

They can also be found sleeping in or on tank ornaments, nestled into the substrate, or floating in place. Bettas are light sleepers and will rest in short bursts, generally at night, with several naps throughout the day. They are most active during the day and prefer to sleep at night.
If you are concerned that your betta is not sleeping properly, there are a few things you can do to help them get some rest. Firstly, ensure that they have a comfortable place to sleep, such as a betta log, live plants, or a leaf hammock. You can also provide different items for them to use as a bed, such as leaf hammocks or logs. However, do not be offended if your betta chooses to sleep somewhere else entirely, as each individual fish will sleep in different positions and places.
It is also important not to spook your betta while they are sleeping, as this can cause them to feel unsafe and lead to health issues. If you need to check on your betta, try to avoid startling them by making sudden movements or noises. Instead, gently check their gills and mouth to ensure they are breathing normally and leave them to wake up on their own.
If you notice that your betta is sleeping more than usual, it could be a sign that they are sick or getting older. Old age can cause bettas to slow down and sleep more. Additionally, if your betta is sleeping at the bottom of the tank, it could be a sign of swim bladder disease, which requires treatment.
