Do Goldfish Sleep ?
If there is quiet time in your home, usually at night, you may find your fish resting at the bottom of the tank among some rocks or plants. Occasionally, the pectoral or tail fins will move to keep the fish balanced. Since they have no eyelids, many people think the fish are always awake. Wrong! They’re asleep.
Goldfish indeed do sleep
and this is the question people often want to know. Sleeping goldfish is not the same as for us cuddling to a pillow under warm blankets. Goldfish usually sleep at one place. They hover with periodic movements to keep stable and are usually seen hiding behind aquarium decorations, aquarium plants or close to the bottom of your aquarium near the gravel. You will see goldfish suddenly swim erratically when you turn the aquarium light on. They are much like us; they were startled and are seeking a place to hide.
Goldfish need sleep just like humans. Without enough sleep we can get sick and same goes for them. People should have a regular schedule for aquarium lighting or better yet have it on a timer so it’s on for a certain amount each day. Your light should be on for about 12 hours a day or less. A good suggestion to do is turn on the light when you get up and when you go to sleep turn it off. When you shut the light off you will notice that your goldfish will begin to slow down and relax. If you leave the light on all the time, it’s not good for
as they will not have much of a resting period. Goldfish have no eye lids so shut off the light so they can get a good night sleep. Goldfish need sleep and it’s much easier to sleep with the lights off. Even if people do accidentally leave the lights on, goldfish will sleep but it won’t be the same type of sleep as if they were off. Try and shut the lights off. Think of this would you like the lights on when you are going to sleep? Same goes for them.
So whenever you go an observe your goldfish and you see them basically still and their color is partially faded, well it is a good chance their sleeping. Leave them alone so they get the well deserved rest they need. Fish that are allowed to sleep in the dark at least several hours every night usually do better than fish that do not get to sleep in a darkened tank.
Goldfish tend to lose some color and luster when they’re sleeping. But don’t worry—it comes right back when they wake up. In fact, to grow to their potential and have their best color, goldfish should have room to exercise and time to sleep. Goldfish need their rest, just like you, so turn the aquarium and room lights off during the evening hours and let your fish sleep. If you don’t turn the light off, the fish will sleep for shorter periods of time or largely go without, which could result in shorter lifespan, less color, and less active fish.
