Thus, check the water temperature immediately. Betta fish need about 8-12 hours of light and 12-16 hours of darkness. They presumably sleep. So, do betta fish hibernate? No.

How Does A Betta Fish Look While Sleeping?

Before moving towards the ‘, do betta fish hibernate?’ part of the question, let us first know exactly how a sleeping betta looks. First and foremost, you should not compare the sleeping pattern of a betta fish with your own as there are different attributes involved.

A sleeping betta fish generally remains quite still while sleeping. The whole body, except the gills and the mouth, remains still. A betta fish uses the gills and the mouth for breathing. Moreover, betta fish do not have eyelids. Therefore, unlike humans, betta fish always open their eyes while sleeping.

Another way to tell whether or not your betta fish is sleeping is by looking at the time. It is generally recommended that you define a proper sleep schedule for your betta fish by regulating the lighting of the tank. Bettas usually need about 8 to 12 hours of light to be awake and swim actively.

Similarly, betta fish also need about 12 to 16 hours of darkness in the tank. Like most humans, betta fish also need complete darkness to sleep properly as recent studies have shown that bettas are capable of perceiving light. Thus, if your betta fish does not move during the nighttime, then it is probably sleeping.

Now the question arises, where do bettas sleep? There is no one actual or ideal location for a betta fish to sleep. This aspect varies from betta to betta. Usually, you may see your betta fish sleeping while floating.

Additionally, you may also notice your betta fish sleeping at the bottom of the tank. However, in this case, you should remember that if your betta fish is sleeping for a prolonged time at the bottom of the tank, it may be a symptom of a problem related to strong filtration or uneven water temperature.

Occasionally, you may also observe your betta fish sleeping on their sides. Well, if one day you see your betta fish lying on its side not moving that much then you would assume that there is a problem with the betta. You have no reason to panic as bettas sometimes tend to sleep on their sides. However, this should not be ignored entirely as it may indicate swim bladder disease.

Other times you may notice your betta fish squeezing themselves among tank objects or sleeping on leaves of the aquatic plants or hiding behind any tank decor. Thus, there is no particular spot for a betta fish to sleep. It completely depends on the betta’s preferences.
