Is tropical fish easy to keep in winter? How to raise?

It's not easy to raise, and it has to be heated and oxygenated all the time.

1. Goldfish.

Goldfish are cold-water fish, they can survive at low temperatures,14 they can be alive and kick around, and they can survive at low temperatures, but their vitality will be much worse. Although goldfish is a cold-water fish, it can be full of vitality in room temperature water (25), and it is an out-and-out durable fish. At the same time, goldfish do not have high requirements for the environment, and they can be raised in bare tanks.

The key one is that the cost of raising goldfish is low, and a butterfly-tailed dragon is only about 30.

2. Koi. Koi fish are as hardy as goldfish, or even better. However, one of the disadvantages of koi is that it eats a very large amount, and mature koi eat more than 2 adult goldfish. The more you eat, the more you come.

This is also the main reason why koi fish are rarely popular among players.

3. Chinese betta fish.

As a native breed, betta fish has always been tepid in the aquarium world, and is often eliminated as a marginal species, just like the Chinese pastoral dog in China. But it is undeniable that betta fish are not only easy to raise, but also very ornamental. Especially in the low temperature and temperature environment of winter, betta fish can live tenaciously and vigorously.

4. Tang fish. Goldfish or white cloud redtail fish, there are many people who understand. Tang fish is a unique species in Baiyun District, Guangzhou, and is not found anywhere else. From the first discovery of the tangyu, to the establishment of a protected area due to endangerment, to today's prosperity, the fame of the tangyu has flattened amid the skyrocketing.

Now Tang fish can be artificially cultivated, and the selection of varieties is very diverse, ** is also close to the people, is the most suitable for raising small pet fish in winter.

It's definitely going to be some good-looking, easy-to-raise goldfish. Goldfish are cold-water fish and do not need to be heated. Koi fish can also be raised.

However, the average goldfish is more expensive. The best tropical fish to raise is the gar, he is also called a small crocodile, and it can not be heated in winter, not fed, and will not die. It's just that it doesn't grow.

Boiled fish, boiling fish is the best, with you through the long winter.

The first thing to do in winter is to control the water temperature, which is the main cause of its death, usually between 20-30. Secondly, it should be fed regularly, and according to its different types, it is necessary to choose a suitable feed for feeding. At the same time, it is necessary to pay attention to water exchange, which can maintain the water quality and at the same time improve the dissolved oxygen of the water body.

When changing the water, you need to clean the fish tank and drain the dirt from the bottom. <

For most tropical fish, 20-30 is the most suitable, a few fish can tolerate a low temperature of about 16, but lower will lead to death. In addition, the water temperature should not be too high, as high temperature will not be conducive to its survival, and will accelerate the reproduction of fungi and increase the possibility of getting sick.

There are many types of tropical fish, and different species have different food needs, some like to eat meat, and some like to eat vegetarian. However, it is okay to feed with fish food, usually two to three times a day, so as to meet its growth needs, insufficient feeding will raise old head fish, not big.

Fish farming usually requires the main change of water, and the same is true for tropical fish. It should be noted that since it has certain requirements for water temperature, the temperature of the new water should also be controlled, usually a little higher than the old water. In addition, be sure to dry it before changing the water, you need to dry it for one day in summer, and it will take longer in other seasons to remove chlorine.

The fish themselves will have excrement, and there are also fish food that may not be eaten and become bait, which will pollute the water quality, and if you do not pay attention to cleaning up, it is likely to affect the survival of the fish, so it is necessary to suck them off the bottom when changing the water. Dirt can also be filtered out with a filter and then broken down by microorganisms.

1. Fish tank: It is a place for tropical fish to grow and move. Fish tanks for raising tropical fish must be made of slightly larger rectangular glass fish tanks.

2. Water suction pipe: used to suck out the dirt on the bottom surface of the fish tank when changing water, and connect it with a soft rubber pipe and a glass pipe to form a morning side. The length depends on the height of the tank. Generally, one meter two to one meter five is taken.

3. Thermometer: used to measure and adjust the water temperature of the fish tank.

4. Fishing nets: used to catch and transfer tropical fish.

1. Early release of fish fingerlings. Early stocking of fish fingerlings can make the fish adapt to the new living environment earlier, eat earlier, grow early, and relatively prolong the growth period. Generally, from the winter solstice to the beginning of spring is the best period for stocking fingerlings. Stocking fingerlings should be carried out on sunny days when the temperature is not too low.

2. Anti-freeze damage. Cold winters often cause frost damage to overwintering fish species, and the following four methods can be adopted to avoid cold and warming: (1) Set up barriers to avoid wind.

On the north side of the fish pond, wooden sticks are used to drive piles around woven bags or straw, and artificial barriers are set up to resist the north wind. (2) Smoke for heating. The howling north wind during the day is a precursor to frost at night, so wet straw and firewood can be piled up on the bank of the fish pond to make a fire to create heating and reduce the degree of frost.

Stocking of aquatic weeds. In winter, a certain amount of aquatic grass is put into the fish pond to keep the fish warm in the grass to keep warm and keep out the cold. (4) Water injection and heating.

On sunny afternoons when the temperature is high, the shallow pond water that has been warmed by the sun is injected into the fish pond.

3. Don't flush in the evening. If you find a floating head during the day, do not flush it with new water in the evening. Because there is very little dissolved oxygen in the water body in the evening, especially the bottom water layer, which is already in a state of hypoxia, the evening flushing will cause the upper and lower water layers to mix, so that the whole pool is hypoxic, causing harm to the fish.

4. Disinfection and immunization of fish fingerlings. When the fingerlings are put into the pond, they should be soaked and disinfected with medicine for 5 to 10 minutes. Vaccination of grass carp and other fish species is more effective.

5. Do not apply organic fertilizer. In order to fertilize the water quality, it is necessary to fertilize the fish pond, but avoid applying organic fertilizer. Because organic fertilizer will consume dissolved oxygen, the pond will be hypoxic. Organic fertilizer also decomposes to produce hydrogen sulfide, ammonia and other products that are toxic to fish and deteriorate the pond water.

6. Prevent flooding. Under normal circumstances, after entering the winter, the phenomenon of flooding ponds is significantly reduced. However, fish cultured in fertile-water ponds, deep-water ponds and cages often suffer from hypoxic floating heads and even death in winter due to negligent management. Farmers should often patrol the pond and solve problems in time.

7. Do not open the aerator machine. It is unscientific to use an aerator to aerrate fish ponds in winter. Because the fish will be frightened when the aerator is turned on, and swim in the water, the only energy in the body and the oxygen in the water will be consumed at an accelerated pace, causing the fish to become weaker and weaker, and gradually die.

8. Prevent illness in advance. Fish are starved for a long time during the winter, which will cause growth stagnation and increase diseases, among which water mildew is the most susceptible. In winter, fish diseases should be diagnosed in time, and the right medicine should be prescribed to prevent dead fish.
