Why do goldfish only live in fish tanks

Only living in a fish tank?

Do you want to ask, why only live in artificial environments and not in wild natural environments?

Goldfish are bred by crucian carp through artificial selection, the purpose of this cultivation is for ornamentation, which makes the goldfish more and more in line with human viewing requirements, and its other aspects are greatly degraded, and it no longer has the ability to survive in the wild.

The body of the goldfish is no longer in the shape of a spinning mallet or other streamlined shape like ordinary fish, and its swimming speed and reflexes in the water have no chance of escaping the capture of natural predators. The exterior is colorful and the target is too obvious. They don't have the ability to forage in the natural environment.

Long-term artificial breeding has made it more and more demanding on water quality, temperature, food, etc.

All in all, goldfish have no natural ability to survive and can only stay in artificial environments. If it is put into a water body such as a pond, river, or lake in the wild, it is equivalent to feeding other animals, and even if it does not enter the stomach of other animals, it will die due to water quality and temperature.

Goldfish don't just live in tanks, rivers, pits, tanks, etc. A fish tank is a glass vessel used to raise tropical fish or goldfish, and it plays an ornamental role. Fish tank is called aquarium, also known as aquarium or aquarium, is a container for ornamental use, specially raising aquatic animals and plants, is an animal feeding area, usually at least one side of transparent glass and high-strength plastic.

The aquarium is home to plants and animals (usually fish, but can also be invertebrates, amphibians, marine mammals or reptiles) that live in captivity. Aquarium farming is also one of the most popular hobbies around the world, with about 60 million enthusiasts worldwide.

In the bustling modern metropolis, fashionable upper-class people are also thinking about how to introduce landscape culture into modern home life. In particular, the introduction of smart water culture has become the main body of the current fashionable home. It is a good choice to arrange a fish tank that blends in with the overall style of the room.

The fish tank is not only a home for the fish, but also a common life for the family. The flawless double-layer float glass not only creates a warm home for the fish, but also ensures the safety of the overall living environment. The art glass patch makes the black base cabinet shine brightly, and the aristocratic blood is unobstructed, like the sea.

Because there are cats on land... Isn't it a brain teaser? )

Because there's a cat outside the fish tank.

You don't have to wipe your ass when you poop!

<>1. Because goldfish are very sensitive, when they get oxygen, they are frightened, and they have many benefits for the fish, increasing the amount of dissolved oxygen in the water, having a strong appetite, good vitality, not easy to get sick, and it is also good for cultivating nitrifying bacteria.

There are benefits; 2. Because the lateral line of the goldfish is very sensitive, as long as the water trembles slightly, the goldfish can make an instinctive response;

3. Because of oxygen and red blood cells in the blood.

combined, so that the goldfish is energetic.

Goldfish always lie flat, possibly with goldfish swim bladders.

Dissonance. Fish Maw Disorder:

Causes] There are many reasons for goldfish to suffer from fish bladder disorder, it is generally believed that this is due to the low water temperature, poor cold tolerance of goldfish, especially in the case of severe frost makes the swim bladder lose its ability to regulate balance. Generally, the body of the fish is too short, and the head has a well-developed sarcoma.

Goldfish species such as birthday heads, lion heads, blister eyes, and butterfly tails with blister tail that are too straight or reversed are more likely to develop this disease.

Symptoms] Sick fish do not die lying on their sides, standing upside down, or even belly facing the sky, floating in the water or sinking to the bottom, when touching the sick fish with their hands, they can temporarily resume normal swimming, but the above abnormal state will be repeated every few moments, and sometimes they can eat, and their growth and development are significantly slower than that of healthy fish, but this fish generally does not die quickly. Once the temperature gradually rises, the condition may be relieved or even almost normal.

Season] is generally more common in late autumn and winter.

Control methods]1) The active method is to move the breeding fish indoors or in a greenhouse before and after winter. If wintering outdoors, it is advisable to bury one-third to one-half of the tank in the soil and cover it at night to prevent freezing.

2) If it is a goldfish lying on its side or sinking bottom, you can use a basin with water to scoop up the goldfish, and then use a small sewing needle to thread non-perishable nylon cotton thread, put on a piece of foam the size of a bottle cap at one end, and then thread the sewing needle through the base of the first strip in front of the goldfish's dorsal fin, tie 2 knots, fasten it on the dorsal fin, and fix the foam buoy on it. The distance between fixing the back line should not be too long, because the goldfish can still be on the side of the bottom of the pool (tank) if it is too long. Don't be too short, too short goldfish can't go down to the middle of the water, feed or swim.

As for the position of the buoy, it depends on the depth of the water level in the tank (pool). In short, it is advisable for goldfish to no longer sink to the bottom and lie on their sides, and the fish body can go down to the middle water to feed. Only in this way can the goldfish swim freely in the water and forage for food without lying on its side and sinking to the bottom.

3) If it is upside down or the body of the fish floats up, and the abdomen is facing the sky, you can use a plexiglass button, and the size depends on the size of the goldfish. The specific method is to fix the button with a soft and non-perishable nylon thread, and then use a basin to fish out the diseased fish with water, while tying a knot at the end of the two threads with the buckle from the button 6-10 cm, and then one person catches the goldfish, and the other person quickly hangs the buckle on the tail handle of the goldfish at the place where the knot is aligned. In this way, after the goldfish is put in the water, the upside-down goldfish is not easy to stand upside down because of the weight on the tail stalk.

And the swimming is still free. But here to explain a point, the button should not be too big, too heavy, if too big, too heavy, the goldfish can not drag the button, it is inconvenient to swim. On the contrary, the button should not be too light, because it is too light to sag, and the goldfish tail fin should still float up or stand upside down.

4) If it is an egg fingerling fish without dorsal fin, when suffering from fish irradiation disorder, the fish body is inverted, the sick fish can be raised in shallow water to control the inversion of the fish body, and increase its water temperature to facilitate the effect.

5) The above phenomenon occurs in goldfish, which is related to factors such as the fish body is too short, the tail is small or turned upward, and the head features are too developed.

The water temperature is too low, the fish are hiding at the bottom, or they are sick;

1. Cold: The symptoms are sluggishness, isolated at the bottom of the tank, ** and fins lose their original luster, the color is dull and buried in the cavity, **mucus secretion is out of balance, adhesion between the fins, can not stretch, **Method: Feed the sick fish with an appropriate amount of Banlan root granules, and feed 1 to 2 grams of 3 to 10 fish;

2. Pintail and explosive infectious diseases: the symptoms are that the diseased fish is restless at first, the fins are tightly bent and the shirt is not stretched, and the swimmer is snake-like or only flicks the tail and does not move forward, as if struggling, and then small pieces or punctate blood spots appear on the pectoral fin base of the orbitomandibular body, **Method: oxytetracycline or chloramphenicol is made into an aqueous solution with a concentration of 1/100,000, and the diseased fish is soaked in it until the disease disappears;

3. Anorexia: The symptom is not eating all day, lying at the bottom of the tank or hiding in the corner motionless, **Method: Change to a new environment, or do not feed for a day or two.
