The Sleeping Time of Betta Fish
Betta fish need to rest every day, but they don't enter a state of hibernation like other animals. To keep betta fish healthy, it's necessary to provide them with eight hours of light each day, and let them rest in the dark for the remaining time.
The Sleeping Patterns of Betta Fish
Betta fish usually sleep while floating on the water surface. Sometimes, they lean against or lie on the aquatic plants. They may also sleep on the leaves, but they will swim down by themselves within no more than one minute each time.
Factors Affecting the Sleep of Betta Fish
The sleep quality of betta fish is affected by the environmental temperature. To maintain their health, the water temperature in the fish tank needs to be kept constant at around 26℃. In the cold winter, it's crucial to pay attention to heating the fish tank to avoid the temperature change exceeding 2℃.
