Bettas, or Siamese fighting fish, are known for their vibrant colours and territorial behaviour. They are most active during the day and sleep in short bursts at night. Bettas do not sleep like other fish, or like humans, as they do not have eyelids and do not enter a deep sleep. Bettas sleep with their eyes open and can sleep in odd positions and locations, such as on leaves, under leaves, or even out of the water.

What You'll Learn
Bettas sleep with their eyes open
Bettas are light sleepers due to their natural instinct to stay alert to potential threats, even in the safety of a home aquarium. They sleep during the night, when it's dark, and may occasionally nap during the day. Bettas sleep in short bursts and do not sleep for extended periods due to their territorial nature.
Bettas do not have eyelids, so they sleep with their eyes open. This makes it difficult to tell if they are sleeping or awake. If you notice your betta being extremely still and floating or lying in one spot, it is likely sleeping. Bettas can sleep in a variety of positions, including curled up on the substrate, lying on one side, or even floating vertically with their head down.
Bettas choose their sleeping spots based on where they feel safe. In their natural habitat, which is rice paddies, they like to hide among leaves or find caves. Some betta owners have observed their fish sleeping underneath leaves, between leaves, or on top of leaves. Bettas can also sleep "out of the water" if there are plants with leaves sticking out of the water, as they can breathe oxygen from the surface of the tank.
To determine whether your betta is sleeping or awake, you can observe its breathing, colour, and position. A sleeping betta will have slower and more rhythmic breathing, and it may lose some of its colour vibrancy, which is a natural defence mechanism to make them less visible to predators.

Bettas sleep in short bursts
Bettas are light sleepers and rest in short bursts, with no set amount of sleep that they require. They sleep during the night, in sporadic 10-15 minute bursts, which can add up to 50 naps in a 24-hour period. This is likely an evolutionary adaptation to ensure they are not vulnerable to predators or threats while resting. Bettas are territorial, and it is their instinct to remain alert to potential threats, even in a home aquarium.
Bettas sleep in odd places, and their sleeping spots may vary. They choose their sleeping spots based on where they feel safe. In their natural habitat, which is rice paddies, they like to hide among leaves or find caves. In an aquarium, they may sleep behind the filter intake pipe, in the corner of the tank, or on a leaf hammock. Some bettas even sleep out of the water, on leaves sticking out of the water, as they can breathe oxygen from the surface of the tank. Bettas can also sleep vertically, horizontally, or on their side, and they may float or bury themselves in the substrate.
If you are concerned about your betta sleeping too much, check the water temperature, as bettas need warm water. If the water temperature is too low, they can go into temperature shock and enter a sleep-like comatose state. If the water temperature is fine, check their diet, as they may need new food if their current food is older than six months.

Bettas sleep in odd places
Bettas are known to sleep in odd places, and their sleeping habits can vary. They are light sleepers due to their territorial nature and natural instinct to stay alert to potential threats. Bettas sleep during the night when it is dark, and they rest in short bursts rather than extended periods. They choose their sleeping spots based on where they feel safe.
Some bettas like to sleep on leaves, either by propping themselves up on a leaf or tangling themselves underneath it. Others prefer to sleep behind the filter intake pipe or in the corner of the tank, wedged between the heater and the acrylic. Bettas can also sleep in floating caves, on top of the filter, on a boat, or resting on the sand. Some bettas even sleep vertically with their heads up towards the surface of the water.
One of the strangest positions that bettas sleep in is "fish out of water." Bettas are labyrinth fish, so they can breathe air and sleep on leaves sticking out of the water, as long as they stay moist. Bettas can also sleep on leaf hammocks, which simulate their natural habitat and provide a comfortable resting area.
Bettas do not have eyelids, so they sleep with their eyes open. They may lose colour when sleeping, which is speculated to be a defence mechanism to make them less visible to predators. Bettas can be hard to spot when they are sleeping, as they become extremely still and may float or lay in one spot.

Bettas can sleep out of water
Bettas are one of the few fish that can sleep out of water. They can draw oxygen from the surface of the tank and breathe like humans. However, they cannot do this for long periods and must remain moist the entire time. Bettas sleep in short bursts throughout the night and do not sleep for extended periods due to their territorial nature. They choose their sleeping spots based on where they feel safe. In their natural habitat, which is rice paddies, bettas love to hide among the leaves of plants or find caves.
If you have a plant with leaves sticking out of the water, you might find your betta sleeping there. Bettas can be found sleeping in odd places, such as behind the filter intake pipe in the tank. They can be extremely still and float or lay in one spot at night, but if this continues for consecutive days or extended periods, they might be sick. Bettas can burrow into the substrate, lay on one side, or float vertically with their head up while sleeping. They do not have eyelids, so their eyes remain open during sleep. They may even lose colour when sleeping, which is speculated to be a defence mechanism to make them less visible to predators.
To ensure your betta gets a good sleep, provide shade during the day and total darkness at night. Bettas are light sleepers due to their natural instinct to stay alert to potential threats, even in the safe confines of a home aquarium. Bettas can be stressed by an unwanted aggressive tank mate, leading to loss of sleep. They may also sleep more during the day if something is interrupting their sleep at night, such as too much light in the aquarium or cold temperatures.
To provide a good sleeping environment for your betta, consider setting up shady spots at different levels in the tank so they can choose their favourite sleeping spot. Floating plants that are betta-safe can help block out harsh light, and decorations like caves, tunnels, and bridges can offer nice spots in the dark. If you notice your betta sleeping on leaves outside the water, ensure the plant is submerged enough so your betta doesn't get stuck and dry out.

Bettas sleep in preferred spots
Bettas are known to be light sleepers due to their territorial nature and instinct to stay alert to potential threats, even in a home aquarium. They sleep in short bursts throughout the night, and each betta may have its preferred sleeping positions and locations. Bettas are known to sleep in odd places, and they choose their sleeping spots based on where they feel safe. They may sleep on their sides, vertically with their heads up, or facing head down into the substrate.
Some bettas prefer to sleep on leaves, either by propping themselves up on a leaf or tangling themselves underneath it. Others may wedge themselves between two leaves or hide among the leaves of plants or in caves. Bettas can also sleep on top of their tank, in the substrate, or even "out of the water" on leaves sticking out of the water, as they can breathe oxygen from the surface.
Bettas may also choose to sleep in specific spots within their tank, such as behind the filter tube, in a corner, or near the heater. They may also rest on the sand or gravel, in floating caves, or on tank ornaments. Bettas can be picky about their sleeping spots, so it's important to observe their behavior and provide suitable resting areas.
It's important to note that bettas do not sleep in the same way that humans do. They do not have eyelids and do not enter a state of deep sleep. They are also very sensitive to disturbances, so it's best not to tap on the glass or try to wake them up.
