How do fish sleep at night?

Some fish, such as the Pacific bluefin tuna (Thunnus thynnus) and the Atlantic cod (Gadus morhua), are known to sleep during the day and wake up at night. These fish are able to do this because they have the ability to regulate their body temperature, which allows them to maintain a constant internal temperature.
