The shape, size, characteristics of the living environment of the goldfish, and the relationship bet

Here are the main examples of body color variations, head shape variations, and eye variations.

Goldfish is an omnivorous fish. Plant-based feeds include aquatic plants, plant seeds, bran, bread, rice grains, etc.; Animal feed includes zooplankton, insect larvae, minced fish and shrimp, animal offal, etc.

Goldfish generally have a lifespan of 5-7 years. The length of life is related to the living environment, feeding technology, species and fish physique. For a species, the growth rate and growth quality of fish are related to stocking density, bait quality, water temperature, and container size.

Goldfish are more adaptable to water temperature and can survive in water from 0-39. However, if the water temperature suddenly rises or decreases by more than 7-8 years, the fish will become uncomfortable and sick, and in severe cases, even die immediately. Juveniles are particularly sensitive to changes in water temperature, so goldfish hobbyists should not take this lightly.

The water temperature of 20-28 is the best water temperature for the growth and development of goldfish, when goldfish swim lively, have a strong appetite, have a strong physique, and have bright colors.

Goldfish also have a wide range of adaptation to the pH (i.e., pH value) of the water, and can live within the range. When the pH is low, the carbon dioxide content increases, the fish slows down, the appetite decreases, and in severe cases, growth stops. Generally speaking, water with a pH value is most suitable for the growth and development of fish.

The main organ of a goldfish.

The body of a goldfish can be divided into a head, torso, and tail. There is a mouth at the front of the head, eyes on both sides of the middle, a nose above the eyes, and gills at the back and bottom of the eyes. The trunk has dorsal fins, pectoral fins, pelvic fins, and is covered with scales, with a lateral line on each side.

The scales of goldfish can be roughly divided into three types: normal scales, transparent scales and pearl scales, among which pearl scales are also called pearl scales, which are light and convex in color, and the edge part is dark, which looks like pearls.

Its head is divided into flat, lion, and goose heads. Lionheads have sarcomas on the epidermis of the crown of the head and cheeks and jaws, whereas goose-headed goldfish only have this sarcoma on the top of the head.

There are 4 types of goldfish eyes: dragon eyes, looking at the sky, blisters and frog eyes. The eyes of the dragon are particularly enlarged and the eyeballs are prominent.

There are two types of tail fins in goldfish: single tail fin and double tail fin. The double tail fin can be mutated into three tails, four tails, fan tails, and butterfly tails. Due to the above-mentioned changes in the external morphology of goldfish, the variety of goldfish is becoming more and more abundant.

Note that the water temperature is controlled between 0-35 degrees and there is no need to use an additional heating rod. In order to prevent parasites and germs, artificial feed should be used. Feed 2-3 times a day, don't feed more, make sure to eat within 30 minutes, don't feed below 10 degrees.

It is best to have a filtration system and change the water by 30% every week.

1. The personality of the goldfish is very gentle, and there will be no phenomenon of big goldfish chasing small goldfish.

2. In addition to the breeding season, goldfish of various internal shapes and colors can be mixed together.

3. The water temperature environment in spring is more suitable for the growth and reproduction of various pathogens.

4. Especially from April to May is the peak season of fish disease---"Barley yellow"。

5. As long as the temperature is suitable, the food is abundant, the oxygen is full, and the water is clear, the little goldfish can be satisfied.

The temperature of the fish tank is suitable, the food is abundant, the oxygen is full, and the water is clear, which is very superior.

It's the characteristic of small crucian carp, hehe.

The characteristics and physical characteristics of the goldfish are as follows:

1. Characteristics of goldfish:

Originating in China, goldfish is also known as "golden crucian carp", which is similar to the carp (cyprinus carpio) but has no mouth whiskers, and is an ornamental fish that evolved from crucian carp. There are many varieties of goldfish, the colors are red, orange, purple, blue, ink, silver-white, five-flower, etc., which are divided into four categories: literary species, grass species, dragon species, and egg species.

In the 12th century, the genetic research of goldfish domestication began, and after a long period of cultivation and continuous optimization of varieties, goldfish from all over the world are directly or indirectly introduced by China. In the history of human civilization, Chinese goldfish has accompanied human beings for more than ten centuries and is the earliest species in the history of ornamental fish in the world.

Goldfish is easy to raise, it has a strange posture, brilliant colors, generally golden yellow, and beautiful shape. Fish can beautify the environment, is very popular with people, is an ornamental fish with Chinese characteristics.

With the efforts of generations of goldfish farmers, Chinese goldfish still interpret the legend of beauty between movement and stillness to the world. There is another saying about goldfish in my country: when it comes to the New Year, the family buys two goldfish for it, and you can have more than enough gold and jade in the coming year.

With the development of fish, goldfish is an indispensable one.

Second, the appearance of the goldfish:

It is a variety of crucian carp, with many species and large morphological differences. The head is large, with flat heads, lion heads, goose heads, pompom heads, etc., and there are many tumors on the head. The eyes are prominent, and the eyeballs are enlarged.

There are many kinds of scales, including transparent scales, bead scales, etc. The fins are large and spreading. There are many kinds of body colors, including gray, red, black, white, blue, spotted, five-flower, etc., and the body shape is long and short.

1. The small goldfish originated in China, also known as the "golden crucian carp", which is similar to the carp but has no traces of the mouth and has a whisker, and is an ornamental fish evolved from the crucian carp.

2. In general, the whole body of goldfish can be divided into three parts: head, trunk and tail. The anterior end of the head is the mouth, and the posterior part has the nose, eyes, and gill cover. Some breeds have sarcomas at the upper end of the head, some have pompomas above the nose, some breeds have bulging eyes, are positioned upwards or have blisters, and some breeds have gills that leak out of the gill covers.

The body of the goldfish is covered with scales, mainly including normal scales, transparent scales and pearl scales. The lateral line of the goldfish is varied, and the number of lateral line scales, lateral line scales and lateral line scales of different species of goldfish is different. Goldfish are easy to raise, they have a strange posture and brilliant colors, usually golden yellow, and a beautiful shape.

Goldfish has a beautiful body and a wide variety of species, its body color is red, yellow, blue, purple, black, white, two-color, three-color, five-flower, etc., its body shape has lion head, high head, blister, longan, pom-pom, pearl scales, butterfly tail, goldfish belongs to the same kind with crucian carp in taxonomy.

Goldfish have strong adaptability to water temperature, and their body temperature can change with the change of water and land temperature, and they can survive in the water temperature of 0 39 degrees Celsius, but goldfish cannot accept sudden changes in water temperature, which is easy to make goldfish die in ascites. Goldfish are social animals, but do not raise too dense bends, otherwise the oxygen in the water is insufficient, the water quality deteriorates, and the goldfish are prone to death and hypoxia death.

Hello, goldfish features include head, eyes, and scales. According to different characteristics, the head shape of goldfish can be divided into flat head type, high head type shed, lion head type, tiger head type, goldfish eyes may be large eyeballs and convex molds outside the eye socket outside the longan, eyeball protruding beyond the eye socket and flipping upward, blister eyes with blisters under the eyeballs, etc. Goldfish scales may be pearl scales, transparent scales, and translucent scales.

Appearance: Very beautiful, some are red, some are yellow, some are black, and some are white, and they are specially made of fish or bread crumbs. Goldfish are ectotherms, and all their activities are closely related to changes in water temperature.

Most of the goldfish's activities consist of foraging for food in the water, and they live in peace and have no habit of occupying territory. At goldfish farms, it is common to see goldfish feeding along the edge of the pond at dawn. When the keeper approaches, they will swim forward in unison, commonly known as begging for food, and then put the bait, and they will immediately swarm to grab the bait.

1. In the feed of goldfish, it must have nutritious proteins, fats, carbohydrates, various vitamins and a certain amount of inorganic salts and trace elements. As the goldfish grows up, the amount of feeding should be gradually increased appropriately, but it can not be blindly fed, especially artificial feed, which should be strictly controlled. Family fish farming can be divided into 1-2 times a day to avoid excessive feed at one time, accumulation of ponds (tanks), and corruption of water quality.

2. Goldfish are easy to raise, and the beautiful goldfish can beautify the environment, which is very popular with people, and is a unique ornamental fish in China.

Goldfish is an ornamental fish that the people of our country are happy to raise. It first changed from a silver-gray wild crucian carp to a reddish-yellow golden crucian carp, and then gradually changed from a reddish-yellow golden crucian carp to a variety of different species of goldfish after being domesticated in different periods.

3. Life habits: Goldfish is an ectothermic animal, and all its activities are closely related to the change of water temperature. Most of the goldfish's activities consist of foraging for food in the water, and they live in peace and have no habit of occupying territory.

At goldfish farms, it is common to see goldfish feeding along the edge of the pond at dawn. When the keeper approaches, they will swim forward in unison, commonly known as begging for food, and then put the bait, and they will immediately swarm to grab the bait.

Goldfish are ectotherms, and they should be kept indoors in winter.
