When Do Fish Sleep? Scientists believe that most fish have regular sleep schedules just like humans and other animals. Most aquarium fish are diurnal, meaning they move about during the day and rest at night. However, some species are nocturnal and prowl at night, spending daylight hours sleeping in a cave or crevice.
How Long Do Fish Sleep? Aquarium fish sleep for an average of eight to 12 hours. Because sleep time is driven by light, plan to keep the aquarium lights on for eight to 12 hours, allowing for 12 to 16 hours of darkness. If you tend to forget to turn off the lights, install a timer to keep things consistent.
What happens when a fish sleeps?
