Is this tank a red fire carp or what kind of carp? 30

Judging from your **, this is not a carp, this is a single-tailed goldfish, also called a golden carp, which is a grass goldfish and belongs to a crucian carp.

The body is slender and short. The golden crucian carp has a strong physique, strong resistance and adaptability, a wide range of eating habits, no need for fine management, and simple rearing; Raised in the pond, if the bait is sufficient, the growth is faster, the weight of the three-year can reach more than 500 grams, the body length is about 30 cm, and the longest can be 50 cm.

In addition to red, it is also available in silvery-white and red-white flowers.

Two are red-scaled koi and one is grass goldfish.

Red carp is afraid of heat and cold, and the fish tank should not be placed on the sunny side as much as possible in summer, and if it is placed on the sunny side, it should also be blocked from sunlight with cardboard or curtains to avoid death from heat stroke. In the event of heat stroke, they should be immediately fished into cool water and placed in an air-conditioned room, and they can be relieved.

Red carp feeding is still relatively worry-free, and after buying it, it has been eaten one after another. When you are busy at work, you can feed once or twice a day, and if you want the red carp to grow faster, you need to feed some live food such as bloodworms.

Red carp are much larger than tropical fish, and the more they eat, the faster they grow, so according to their body length, change to a larger tank at the right time to give them enough space to swim.

Carp like to live in the lower layer of the water body, the optimal growth water temperature is 25-32, higher than 32 or lower than 15 The growth is significantly slowed down, and below 10 stop feeding. The appropriate amount of dissolved oxygen is above, less than 2mg l is eaten, 1mg l is stopped and the head is floated. Fish farming starts with water.

Water is quite important for fish farmers, and it is generally divided into four types:1It is new water, that is, tap water that has just been dried or freshly dug well water.

Although the water is clean, it is very different from the environment in which fish live in nature. Since there is no nitrifying bacteria community in the water, fish excrement and scattered food residues decompose into ammonia after deterioration, and fish are highly susceptible to poisoning. 2.

It is old water, light green or light amber, rich in humus and beneficial microorganisms and algae, and has established a good ecological circulation system, which is decomposed into nitrate that is harmless to fish through nitrogen cycling. This water is extremely beneficial for the growth of fish. 3.

It is green water, and the organic matter content in the water is excessive, so the cyanobacteria, green algae and brown algae multiply, the content of bacteria and microorganisms increases dramatically, and the water is thick green, sometimes it will emit a foul smell, which is very easy to cause the whole tank of fish to die. 4.It is the return of clear water, also known as biting clear water, is that the content of algae and microorganisms in the green water is too much, which depletes the oxygen in the aquarium, causing the death of algae and aerobic bacteria, making the water become extremely clear, without oxygen and with a large number of anaerobic harmful bacteria.

Not all water is suitable for the life of goldfish, the most suitable water for the growth of goldfish is old water, and the so-called water cultivation is the process of transforming new water into old water. Most of the water used to raise fish is tap water, so the first step in water farming is to remove chlorine, a toxic substance in tap water. The method of chlorination removal is relatively simple, let the water stand for 2-3 days, or dry for 1 day (if it is urgent, you can add grams of baking soda, that is, sodium thioate per 100 kg of water, and use it immediately).

Small fish tanks are not suitable for raising carp, because carp are large fish, and small fish tanks will affect its growth rate, but it doesn't matter if you keep them for fun. It is recommended to change to a large fish tank.

Physical features: The body is spindle-shaped, with a lower mouth, and a pair of snout and jaw whiskers. The gill rakers are short and the abdomen is rounded. The scales are large and rounded. The lateral line is pronounced and slightly curved. The caudal fin is deeply forked. Light red, orange or golden yellow in color.

1. In spring (March to May in the solar calendar), the temperature gradually rises, generally between 10-20 degrees Celsius, and the water temperature environment is more suitable for the growth and reproduction of various pathogens, especially in April and May is the peak season ---of fish disease"Barley yellow"。When the fry hatch in early spring, the eggs are susceptible to water mildew; Fish fry mainly suffer from fish diseases such as wheel worms, melon worms, ring worms, compound mouth flukes, and fish lice; Adult fish in spring are susceptible to microbial fish diseases, such as viral hemorrhagic disease, enteritis, gill rot, printing disease, and silver carp iodosporidiosis.

2. In summer (June-August in the solar calendar), the temperature is generally between 26-28 degrees Celsius, and the incidence of fish is slightly less than that in spring. As a result, ciliate and flagellate fish diseases are gradually decreasing. In addition, according to the investigation, there are still microbial fish diseases in the spring, such as gill rot, hemorrhage, red skin, enteritis, and printing disease.

At this time, the parasite with anchorhead eel disease is more common. In the middle of summer, high-yield ponds are often prone to flooding.

3. Autumn (September to October of the solar calendar) temperature gradually drops, the temperature is generally between 23-15 degrees Celsius, the water temperature environment is basically similar to spring, especially in August to September is the peak season of fish disease--- Bailuxin", summer flower fish species mainly suffer from wheel worms, melon worms, ring worms, compound flukes, fish lice and other fish diseases, and large-sized fish in autumn are susceptible to microbial fish diseases, such as viral hemorrhagic disease, enteritis, gill rot and other diseases.

4. In winter (December to February of the solar calendar), the temperature is low, generally between 3-6 degrees Celsius, and fish diseases rarely occur. Winter is the stocking period of fish fingerlings, often due to the net or transportation of the fish carcass, can also occur water mildew;When the water temperature is high, there is a possibility of oblique tube worm disease and melon worm diseaseWhen the water temperature of the wintering fish is lower than 10 degrees Celsius, due to the large temperature difference between the air temperature of the wintering house and the water temperature, the fish will lack oxygen and float the head, causing chilblains on the top of the head.
