Do goldfish sleep?
All living things sleep or do rest in some way. Goldfish
however can't close there eyes and they will just be laying on the
bottom of the tank. You have no need to worry if it's dead unless
it is laying upside down.
Fish don't really sleep. They just kind of rest by floating in the water, staying quite still.
Amazingly, NO :) they rest in the tanks. how they do that?
UV light(s) influences behavior, physical appearance, and overall health in goldfish. They control when and at what times a goldfish will sleep, they also play an essential role in the color of the goldfish (a lack of light will result in paler fish), and provide energy for aquatic foliage- which results in the production of oxygen resulting in consiquently healthier fish.
