The goldfish are now more than 125 species that have been bred by hybrids, so the colours and heads can be described as varied, so the novels sort out for you the most common species of goldfish and their characteristics, as well as the head classification of goldfish. Friends who like goldfish can simply understand it.
I. Categories common to goldfish
1 Grass species: Golden species of the city. The main ones are single-tailed and scrawlfish, with flat-side hammers, back fins, chest fins in triangles, long and sharp, which are the original species of goldfish and the main species of goldfish currently in the country ' s vast area of aquaculture. The figure is gold, short tail, single leaf, dimpled; orange red, the oldest goldfish species.
2 Monuments: Monuments of goldfish have evolved as a result of the domestication of herbs and their continuous selection for breeding, overlooking the fish like the word “manufactured” and therefore known as goldfish. There is a large variety of colours and varieties of goldfish, most of which are well-known best-selling products on the international market. Common goldfish are classified as high head (hat), pearl (plains) and sculpting fish.
3- Dragon species: ancient goldfish have been regarded as authentic Chinese goldfish, known for its particularly large eyes. Since its introduction into Japan in 1895, it has been known as Chinese goldfish.
Eggs: A short circle of goldfish, shaped like duck eggs. Its life force is faster than the walls of dragons, goldfish and goldfish. Egg goldfish are famous on the international market, whose main characteristics are short and fat, like duck eggs, with no back fins. There are double tails and hips. The length, shortness and shape of fins vary considerably. The fins of general velvet balls, bubbles, tiger heads, etc. are short and round; the fins of Danphoon, thallium, red head, etc. are larger.
II. Common head patterns of goldfish
1. Flat heads
Its head skin is thin and smooth, called a flat head. There's a narrow flat and a wide flat.
2. Goose heads
The tumour on the top of the head is thick and thick, and the gills on both sides are thin and smooth.
3. Lionhead
The tumours on the head and on both sides of the gills are thick and can even cover the eyes when they are developed.
In addition, the common titles of the header are:
1. Lions
The tumours on the head and on both sides of the gills are thick and can even cover the eyes when they are developed. There's a back fin.
Top 2
The tumours on the top of the head are thick and thick, while on both sides are thin and smooth, with back fins.
3 Tiger Head
The tumours on the head and on both sides of the gills are thick and, in the developed world, cover even the eyes with no back fins.
Four, geese.
The tumours on the top of the head are thick and thick, while the gills on both sides are thin and smooth, with no back fins.
Five, the birthday star.
One of the tiger's heads, the top of the head, is the head of an Antarctic fairy, and is called a birthday star.
Six, the lion head.
One of the tiger's heads, the head tumours are very well developed and the aristocratic form is predominant.
Seven, Lan Sui.
One of the tiger heads was nurtured by Japan. Two kisses. However, the side-vision of the tumours was not accompanied by a large size of Chinese tiger head, lion head, birthday star head, cat head tumour, nor was there any visible national head tumor.
The Crown Head
The crown pearl goldfish has a unique head tumor, a smooth single tumour. Goldfish.
The most important concern for goldfish is the quality of water, and for goldfish, soluble oxygen in water, water levels and water exchange are crucial in raising it. It is only clear that goldfish are able to avoid health problems during seasonal shifts.
I. Solvent oxygen
A higher amount of soluble oxygen is found in natural water, which refers to rivers and lakes up to 8 - 12 mg/L, but under artificial feeding conditions, the small openings of fish pools and tanks are limited, light is limited and the density of the animals is relatively high. Aerobics can be operated for about eight hours a day if fish are of smaller density. If the density is high, it should be open 24 hours a day.
In addition to oxygen, there is a condition for light, which is important for the transformation of water quality and watergrass growth, as well as for UVs in sunlight. Lights can therefore be supplemented with UV lamps for several hours per day to supplement the sun.
Water level
A goldfish with excessive perturbation tends to be oversized, flat in the abdomen, short in the tail and thin in the head. In addition, it is important to have previously seen fish mates' posts, and the water for goldfish is best supplied with light green water with small amounts of zooplankton algae. If this water is too deep (more than 50 centimeters) the fish will be invisible. For this purpose, it is proposed to raise goldfish at a low level (not exceeding 40 cm) with static water at a level above 50 cm or higher, with a temperature difference above or below the summer. A very simple example, you can see in the park that the lake is full of goldfish, with no high-quality goldfish.
III. Water exchange
The exchange time should preferably take place after 4 p.m., when the goldfish is fully fed, and when the water is replaced, the rest of the feed and all the contamination in the basin is removed, followed by an appropriate amount of sun. Water is exchanged by netting gold fish basins, dirty matter floating on the surface of the pond and smog, then by twirling gold fish basins in the same direction with a gauze net, and water in the ponds in three to five laps, so as to concentrate the contamination in the water, then by sucking it out with a straw and placing it on the edge of the basin (battle) at an appropriate rate, and by pouring it into dried water. Goldfish breeding environment
The goldfish are born in China, and the domestic feeding rate is very high. To produce a healthy goldfish, care must be taken to create an environment similar to that in the wild, so that the goldfish can be more beautiful and healthy to accompany you.
I. Water temperature
Goldfish are warming animals, and body temperature changes with water temperature. But summer and winter temperatures are also a test for goldfish, so try to keep them warm.
II. Density
The small size of the home-grown rectangular aquariums is such that they cannot be nourished. In containers of 40 cm long, 25 cm wide and 30 cm high, small goldfish of 5 to 7 cm long can be raised at the end of 6 to 8. A round glass tank with a diameter of 26 centimetres and a height of 13 centimetres can feed 4-6 centimetres of small goldfish with 4-6 tails. A fish of more than eight centimetres in size should not be raised in a small glass tank, but rather in a large glass tank or in a ceramic tank, backed up by a small oxygen-filling machine. These concentrations are only reference figures and are determined by the temperature of the water, the strength and strength of the fish and the quality of the water, which cannot be done mechanically. Generally, fish are big and poorly fed; they are fed more in the winter and less in the summer; they are fed more when water is low and less when water is high. Goldfish feeding requirements
Like many animals, a single recipe leads to uneven nutrition of goldfish. The goldfish feed must contain abundant proteins, trace elements, inorganic salt, etc. So when the goldfish should be fed, it's the fish friends' problem.
First, animal feed. For example, red worms, daphnia, daphnia sacrificial fleas, herbicides, larvae, larvae, larvae, earthworms, etc. These fresh fish feeds are rich in nutrients such as proteins, and goldfish are also the most popular exotic fish.
Second, vegetable feed. For example, there are weeds, weeds, etc. Plants have little roots and are better nourished, but goldfish is the best feed for an animal. Thus, some animal feed can be properly fed with a balanced diet to ensure the healthy diet of goldfish.
And third, synthetic feed, which is the usual, marketed fish-dry feed. General professional production of fish feed, both nutritionally and proportionally, is very good. They contain nutrients such as proteins, sugar, fats, vitamins, inorganic salt and have already met the nutritional needs of goldfish growth. Moreover, such fish feeds are easily purchased and easily fed. This synthetic dry feed is usually the first feeder to feed the fish.
If conditions permit, no long-term, single-term goldfish feed only one fish feed. We can change it on a regular basis, properly add some animal feed, and make goldfish diets richer.
