Do domestic tropical fish sleep, do tropical fish sleep?

Will sleep. According to the staff of Nanjing Underwater World Aquarium, because the fish have no eyelids and can only open their eyes when sleeping, people cannot find them even if they are asleep. Light is very important for tropical fish to survive, and tropical fish cannot survive without light.

There are three main effects of light on the rearing of tropical fish.

Although there are many kinds of tropical fish and their habits are quite different, their feeding habits can be roughly divided into three categories: carnivorous fish, which account for the vast majority of tropical fish; omnivorous fish, which make up a small percentage of tropical fish; Vegetarian fish, which make up a very small fraction of tropical fish.

Scientists have found that global warming is forcing marine species to disappear from hotter habitats, and that twice as many marine species are forced to move than terrestrial species, especially near the equator. The subjects of the report were cold-blooded animals (homeotherms). Under the current warming trend of the ocean, the habitat of cod, snapper, catfish and stone crab will be reduced by about 20% in both the North Atlantic and North Sea waters.

Any animal needs to sleep, and so do fish.

Problem description: Last week my son asked me if tropical fish should sleep? When to go to bed? How long to sleep?

Since I didn't know anything about this problem, I thought of raising it myself, so I went to the aquarium and bought a bunch of fish farming equipment and some tropical fish, I stared at these fish for two days and two nights, as if I didn't find them sleeping, just moving and stopping, please help me find a correct answer, thank you! I only have 31 points of silver, all of them, thank you.

Analysis: You're such a good dad (or good mom?) ）

Fish have to sleep, too. It's just that there are no eyelids, so you can't see it. Sometimes you see it standing still in the water, just its cheeks open and closed, then it's sleeping.

A little fun stuff to add:

Fish that rest during the day account for the majority of nocturnal carnivorous fish, such as trouser eels, catfish, conger eels, flounder, moray eels, etc.

Most of the fish that fall asleep in low-light conditions are freshwater fish and fish that survive in shallow waters, such as carp, fish prints, and stone bream, among which humphead fish flock to the "bed" of the sand pile in the evening to sleep soundly. As soon as the sun came out the next day, the sand pile was drilled. They also hibernate.

Hibernation fish include carp, fish prints, herring, eels, and sardines. They look forward to a warm spring in the sand or mud.

In contrast, fish that need a period of rest in the summer can be found in freshwater fish that live in hot regions, such as the barramundi in Africa and the loach that lives in the waters along the Danube.

People need sleep, and so do fish. Just as humans sleep in various ways, fish sleep in a variety of ways. If you look closely at the goldfish we raise, you will find that at night, they will hide in the small rockery, aquatic plants and other dark places in the fish tank and remain motionless.

This is the state of the goldfish when it sleeps.

Fish do not have eyelids like humans and are able to close their eyes when sleeping. Therefore, it is not easy to grasp their posture when sleeping. The following is a list of several fish sleep states for students, please pay attention to them. Laughing Jane.

Some fish such as flowers, sea pigfish; When night comes, they will burrow into the sand and sleep motionless, which is quiet and effective against predators.

Some fish, such as split-billfish and South Sea parrotfish, will secrete a special gelatinous substance in its body, and when they want to sleep, they blow a big bubble like a child, and the gelatinous bubble hardens when exposed to water, and then they get into the bubble, leaving only a small hole in the mouth, just like in a sleeping bag.

Most of the fish that live in freshwater sleep behind rocks and in the dark of aquatic plants. Like carp and crucian carp burrow into aquatic weeds, while mullet and snapper sleep behind rocks.

Migratory fish, on the other hand, swim and sleep at the same time. For example, tuna, mackerel and chiayu swim back and forth day and night, making it difficult to figure out when they are sleeping; When is awake.

Tropical fish sleep. Any fish sleeps, but because they don't have eyelids, they look the same when they're sleeping and when they're awake, so it's hard to tell the difference. However, usually a fish that is asleep does not swim, it will stay in one place for a long time, and if it is awakened by a vibration, it will often swim immediately.

In order for the fish to have a good rest, it is best to turn off the lights at night. <

1. Avoiding predators: Fish tend to avoid being attacked by predators during their sleep. There are also many ways to dodge, and common fish will hide in aquatic plants or rocks.

There are also benthic fish that bury themselves in the sand. Some fish are able to spit out bubbles to wrap themselves, leaving the other party with no way to eat.

2. Sleep with your eyes open: As mentioned above, most fish have no eyelids, so they sleep with their eyes open. For diurnal fish, there is no light at night, so they can sleep peacefully, while nocturnal fish are more photophobic and tend to hide under the water or in burrows to rest during the day.

3. Sleep while swimming: Some fish have a special body structure and need to always keep swimming, otherwise they will die. The same is true for these fish when they are sleeping, so it is difficult to tell if they are awake or not.

I also just raised a pair of tropical fish, if the conditions are good, just buy a heating rod, don't be too diligent in changing the water, use warm water, don't be too hot, or the fish will be too active, feed once a day, there is no need to feed any earthworms, it's disgusting, just buy a pack of tropical fish food.

1.Adjust the water temperature to between 24 and 28 degrees, and the water temperature should be constant.

2.Sprinkle some salt with each water change to prevent disease.

3.Keep the fish semi-starved and feed them regularly so that the fish will be more active.

4.If you use tap water when changing the water, expose the water to the sun for three days.
