Do betta fish hibernate

    Do Betta fish sleep? It is possible that you don’t think it is essential for our fish, but, like other species, sleep contributes massively to a healthy and happy Betta.

    We’ve covered all the information you need to know, from how to determine whether your Betta is asleep to creating an environment that promotes sleep.

    We must first consider what sleep looks like in Betta fish. In humans, at night, we switch between REM or NREM stages.

    In the REM state, we are in a state of sleep, it becomes difficult to wake up, and it slows down our reaction time when we wake up quickly. Fish, on the other hand, the sleep phase is entirely different.

    Consider it more of a sleeping state. Betta fish have to be able to respond quickly in the face of threats to be able to live.

    Although your fish have probably been raised in captivity, and your aquarium is a secure and predator-free area, the instincts remain.

    All Fish Need Sleep

    Fish might not be able to snuggle themselves in bed at night but generally sleep at one time or another. Fish that are most active during the night sleep throughout the daytime. Fish such as Bettas which are most active during the day, do most of their sleep during the night.

    How To Tell Your Betta Is Sleeping

    There are several ways to determine if your Betta’s sleeping. It is possible to see them asleep, laying motionless and unaware of whatever happens within the tank. In an L-shape, it could be near the surface or in the middle of the tank. It may even lie sideways. You could even locate it hidden in places like the plants or the rock in the tank. These are ideal spots for your Betta to retreat and feel secure enough to lie down when needed.

    Why Do Betta Fish Sleep?

    They naturally prefer to rest and do this in the evening or the evening when temperatures are lower. This is a method for them to reduce their energy consumption and avoid active activities during the day when there is more pressure to eat. But, when the weather turns cold certain betta fish go to sleep to conserve energy and shield them from harsh weather. They are tropical fish that usually live in slow-moving waters. They are active throughout the day. However, they tend to lie down in their aquariums in the evening. There is a belief that betta fish lie down to save energy. Betta fish typically sleep curled up with their head snuggled under their bodies.

    How To Encourage Your Betta To Sleep

    There are some things to help you, Betta, to get enough rest.

    The most important thing is ensuring he has time to rest with the lights off. As fish keepers, we often cannot appreciate the importance of attempting to replicate the natural way of life for our animals. The best way to do that is in a tank of fish!

    One method to accomplish this is to give them the option of 12-14 hours in darkness. It is likely that Betta is most comfortable sleeping at night and has small naps throughout the daytime.

    Another thing to be sure of is to make sure your filter isn’t overly robust. You do not need your Betta being moved about by the current.

    It will be difficult for him to locate the perfect resting spot that’s not on the tank’s floor.

    Why Do Bettas Sleep a Lot?

    In the realm of fish, bettas belong to the more lazy category and require more extended rest periods than other fish species. The long, intricate fins need a lot of energy to move into the ocean, and a characteristic different fish species do not possess. Certain varieties of goldfish could also feature long fins. These fish require much more energy to swim than their shorter-finned counterparts, especially with slim, compact bodies.

    Imagine swimming in a pool in a ball gown. Swimming in and dragging around a large amount of fabric is difficult, which doesn’t help you float. This is like a betta fish carrying around a lengthy ornate tail. They rest for extended intervals between meals to stay alive for the long haul.

    The temperature is crucial to optimal fish activity, which includes growth, metabolism, and immunity. Different species of fish have a particular temperature they perform optimally at. For bettas, this is a tropical temperature between 78 and 82F (25-28C). Your tank for bettas requires a heater to ensure that the water is at the right temperature to allow them to perform its activities. If the water in your tank is frigid, the Betta may be sleeping more often than usual simply because they have an accelerated metabolism.

    Do Betta Fish Need Darkness To Sleep?

    The answer is a bit ambiguous if you’re looking for Betta fish. Switching off the lights will allow your fish to recognize when it’s night and create a sleep pattern.

    But, you’ll find that bettas may also nap in the morning when they have sunlight. It is essential to give them 8-12 hours of daylight with 12-16 hours of darkness for the bettas to get a good amount of rest and to establish the habit of sleeping.

    What Does a Sleeping Betta Fish Look Like?

    A betta that is asleep typically has its body in a completely still position, with only one head movement. The eyes could be closed, and the mouth open. If you are a behaviouralist and walk into the tank and rub the betta fish that is sleeping gently, it may shake its body a bit. The absence of movement is because of their relaxed state rather than stagnation; they are not stuck or immobile.

    How To Tell When Your Betta Is Sleeping?

    In essence, if you observe that your Betta has been inactive for an extended duration in the tank, he’s likely asleep mainly if the extended period of inactivity is at night.

    What Does It Mean if Your Betta Fish Sleeps All the Time?

    If your fish is sleeping for a long time, This is not good sleep. It is important to note that continuous torpor is called “biochemical starvation,” where your fish loses its nutrients and eventually dies due to insufficient energy.

    In addition, if your Betta’s sleep pattern is constant throughout the day, it could indicate that it’s not well. Try feeding it fresh water and food and see if this aids. You might have to take this animal to a vet if it does not work.

    Do Betta Fish Hibernate?

    No, betta fish do not hibernate.

    Hibernation is beneficial for some species to survive the winter cold. Bettas come indigenous to tropical freshwaters of Asia. They do not meet the requirement to hibernate since the water stays warm.

    If you feel that your Betta is less active in the winter months, consider whether the water is warm enough. If it’s not as warm as it should be, the Betta’s lack of activity is probably due to a temperature shock.

    The temperature shock can be deadly as you could endanger your fish by warming the tank back to its optimal level.

    How Can You Help Your Betta Fish Sleep?

    You can take some actions to ensure your baby has the best chance to get an excellent night’s rest (plus napping for a couple of hours). This is essential to keep your pet as healthy and happy as possible.

    The most crucial factor you can do is keep a strict schedule for lighting. Bettas require a regular light cycle to replicate the day and night process to determine when it is time to sleep.

    Ensure that the lights are turned off at the exact time each day. You can buy an aquarium timer to automate this task for you.

    It’s not necessary to keep your lights running for too long. Around 8 hours of lighting is sufficient. This should suffice for the live plants you keep to produce photosynthesize too.

    The lights being on for longer than this can keep your bed awake through the night and will encourage algal growth.

    Even with the lights up, your dog may be tempted to sleep. They’re not likely to do this in bright lighting, so providing them with caves or places to lie is essential.

    It is easy to make using decorations or plants as you design your aquarium. You can add a few spots for them to choose from.


    As you can see, bettas do sleep. They also sleep in unusual locations, which can cause many to believe they’re dead. If you observe your betta fish at the surface or near the bottom and still motionless, they may be sleeping.

    To prevent yourself from being scared each time you encounter this, it is recommended to switch off the tank light and the lights around it when it’s time to fall asleep. This will allow them to establish an evening routine where they can rest comfortably at night and remain active throughout the daytime. Remember that every Betta fish is unique, and some prefer sleeping throughout the day.

    The time to investigate why the tank is not active is when it’s not the norm. It could be because of lighting that interrupts their sleep or even a tank with temperatures lower than 75 degrees. In any case, they can rest when they are required.
