Betta fish sleeping behaviour
Betta fish require dark like us to sleep.
Bettas sleep at night and mostly remain active during the daytime.
So, it is necessary to maintain the day-to-night cycle by providing light during the daytime to your betta.
It is advisable to add an aquarium light to your betta tank, keep it on for at least 8 hours during the daytime, and keep it off at night so your bettas can sleep in the dark.
Bettas needed a flat surface where they could sleep peacefully, whether a long leaf or a flat rock decor.
However, they will also sleep on the substrate of their tank.
Like all other fishes, bettas also don’t have eyelids and have a lateral line to sense any movement and vibration in the water and get alert as soon they feel any threat.
Is it normal for bettas to sleep most of the time?
Betta fish’s long fins take a lot more energy to pull through the water.
Also, in the fish world, bettas come under the fishes known to be lazy and require longer rest periods than most other fish.
If your betta fish is active during the daytime and eats all its meals regularly, it is fine.
Also, it is normal if your betta sleeps during the daytime but is always active when you feed them, and there are no signs of illness or injury.
However, if your betta fish avoids eating, hiding in a spot, and sleeping most of the time, it is a matter of concern.
Many things can make your betta sleep a lot, primarily inadequate water conditions and parameters, illness, and stress.

What to do if my betta is sleeping so much?
To prevent your betta fish from sleeping so much, you must first ensure adequate water temperature.
Betta fish require a warm water temperature between 78-82 °F.
You must add a heater to your betta tank to ensure stable water temperature.
Also, make sure the water parameters are adequate.
Betta fish require a pH level between 6.5 and 8, ammonia and nitrite at 0 ppm, and nitrate below 20 ppm.
Now, if the water is warm and all the other parameters are adequate, look for the food you feed your betta fish.
If the food is six months old, you must replace it as it has lost all the nutrients and vitamins that your betta requires to stay healthy and active.
Feed your betta fish with a betta pellet and make it a staple part of their daily diet.
Ensure feeding your betta fish two times a day with 2-3 pellets or any other food at a time to ensure adequate feeding and avoid overfeeding.
You can feed your betta fish with live, frozen, and freeze-dried food, but make sure it should not be a staple part of their diet and should be provided once a week.
After all that, if your betta fish is not being active and continues to sleep most of the time, it’s time to reach your fish veterinarian.
It is possible that your betta is suffering from some sickness and need proper medication to recover.
Cold water temperature, stress, and poor water conditions are the primary reasons your betta fish sleep so much.
However, if your betta fish is just a lazy personality or older, then it is normal for them to take longer naps.
Betta fish require more energy to pass their long fins through the water, so they take more naps to regain their energy.
If your betta fish is sleeping more but regularly eating and have no sign of illness or any injury, it is normal and nothing to worry about.
However, if your betta avoids eating and is sitting in one spot most of the time sleeping, it may be suffering from illness, or the water parameters and conditions are not adequate.
