There are water lilies or lotus flowers in the flower pond. I can only tell you so many details. I hope you don't take it personally.
In my experience of raising koi fish, more than a dozen people died in the first two months, that is, with the firm belief of never giving up, I walked out of the misunderstanding of raising goldfish as usual. Looking back now, I also found that I had some mistakes in raising golden fish. The following content is based on the idea of feeding koi fish first. I hope I can help you.
In fact, koi fish is not difficult to raise, or an old saying goes; People who don't know how to raise fish can feed koi fish for a year or two. However, it does not mean that it can be raised on a large scale. It should be emphasized that koi fish consumes a lot of oxygen. If kept in aquariums or other small containers with high feeding density, a pump is necessary equipment. Koi fish has a lot of excreta, so it needs to be kept in a bare tank, and water filtering devices are also indispensable. Koi fish swims fast and likes to jump. Don't put ornaments in the fish tank that may harm koi fish and the fish tank. Cover the container. The minimum size of the fish tank should be 80 cm long (this tank can only support 2-4 koi fish with the size of 20-25 cm). Of course, it is best to use a larger container, because we have to consider whether koi fish will stay or not after being raised. But if you don't even have an 80cm tank now, it doesn't matter. Feed the fish successfully first, then make plans.
Choosing fish is the key to raising koi fish. Buying small fish with the size of 10-20 cm has the highest success rate. When choosing fish, you should see whether the water is too muddy and whether there are a few rotten fish in school. If that's the case, you don't have to look at the fish in this pool. If this passes, you can watch the fish you want quietly. Never buy short-headed, blunt, thin or bloated fish. Choose fish with symmetrical body shape, active swimming posture and bright eyes. Cheap fish, the color is generally not too good, as the saying goes; You get what you pay for, but you are still in good health. After choosing the fish, remember to ask the store to oxygenate your fish. After taking the fish home, don't open the bag in a hurry. Put the whole bag with fish on the surface of the feeding water for 45 minutes-1 hour, so that the fish can gradually adapt to the temperature of the feeding water. Then open the bag, let the fed water gradually mix with the water in the bag, and then put the fish.
In the next few days, water is the most easily turbid. It is best to change the water supply of 1/2-2/3 every day. If your fish container is too big to change such a large amount of water, you can put it in a suitable small container for two weeks. When you see the fish start to improve, you should catch it in a fixed container, and remember to balance the water temperature of the two containers before fishing. Whether it is temporary or fixed, it is best to put enough activated carbon in the water filter to minimize the amount of harmful substances. After keeping the fish stable, if koi fish is kept in a small container such as a fish tank, it is best to change the feeding water of 1/8- 1/3 every four or five days according to the different water quality, which is very beneficial to the healthy growth of koi fish and keeping the water quality clean.
In the whole process of raising koi fish, there is generally no need to put preventive drugs, and blindly using drugs will only kill fish. Individual sick fish should be isolated in time, observed for a few days, and then treated separately. Activated carbon should be taken out when taking medicine, and the medicine should be light but not strong. Pay attention to observation. Once the fish is found to have an uncomfortable reaction, change the water in time. Commonly used drugs are; Huangpai Yubao panacea (mainly composed of methyl blue) yellow powder and potassium permanganate (just adjust the bath water to pink).
Koi fish should feed it two or three times a day, and the feeding amount shall be subject to eating the feed within ten minutes each time. I suggest you buy bulk spices (a mixed pellet feed with a brown smell).
Feeding techniques in koi fish.
1, feeding density
Before feeding koi fish, we should first consider the size of the feeding container and the mantissa of koi fish. Koi fish's appreciation mainly lies in its gorgeous colors, lithe figure, graceful movements and graceful group swimming posture, while koi fish must look from the back, that is, obliquely above, which is the best, but not as good as looking from the side. To fully meet these conditions, only gardens and ponds can be raised. But as city residents, not everyone has a garden, so they have to use an aquarium instead. The feeding density should be adjusted according to the size of the container, water quantity, water temperature, aerobic state, fish size and growth.
2. Variety collocation
When raised in the garden pool, it is generally matched with red and white, Dazheng tricolor, Showa tricolor, gold or platinum, autumn water and light yellow. In the aquarium, people can only see one side of koi fish, and they can choose reflective fish, such as gold, platinum, pine leaf gold, mountain blowing gold and other koi fish, and then match German carp. But whether they are kept in underground ponds or aquariums, most of them are mainly koi fish with bright colors, supplemented by dark, shiny and elegant ones.
3. Bait method
Koi fish is an omnivorous fish, which can be fed with animal or plant food, such as Daphnia, earthworm, shrimp, corn flour, biscuits, instant noodles, vegetables and even rice balls. However, in order to make koi fish colorful, besides factors such as light, background and water quality, it is more important to feed special koi fish artificial feed with high nutrition, which is flaky or granular.
Baits can be thrown individually or alternately. Koi fish is a gluttonous fish. Eating too much will lead to food accumulation or constipation. Therefore, we should pay attention to the frequency and frequency of feeding, and take the principle of eating less and eating more meals, leaving no residual bait and no bad water.
For hatched young fish, rotifers, Daphnia or egg yolk can be fed first. Small fish about 2 cm should be fed with bait such as red worms. For fish that grow to more than 5 cm, you can eat animal or plant bait at will.
Water lilies are also called water lilies, meridian lilies and perennial aquatic flowers of Nymphaeaceae. Native to East Asia, I like strong light, high temperature, humidity and well-ventilated environment. Cold-resistant, but avoid freezing. The choice of soil is not strict, but fertile soil rich in organic matter is better. Propagation can be accomplished by dividing plants or sowing. Generally, the rhizome is dug out in late March, cut into small pieces with the length of 10- 15 cm, and then planted. The sowing method is potted in March-April, and the temperature is kept at 25-30 degrees, and it can germinate in about half a month. When the seedlings have 3-4 true leaves, they are planted in pots.
Potted water lilies should be changed once a year in spring. When changing pots, it is best to choose pots with an inner diameter of more than 30 cm, so that plants can fully stretch and grow normally. Make the leaves bigger and the flowers bigger. Pot soil is pond soil or garden soil. Put a few hoofs or broken bones at the bottom of the pot as base fertilizer. After planting the rhizome, cover it with a layer of topsoil such as river sand and mud, and pour enough water. After budding, soak the pot soil in water, the water surface is slightly higher than the soil surface, and put it in a ventilated and sunny place for maintenance to keep the water clean. With the increase of temperature and the extension of leaves, water should be gradually added. It grows vigorously in summer and the water level is slightly deeper. Irrigation can be up to 20 cm deep, but the leaves can't be flooded. If you want to change the water, it should be done in the early hours of the morning.
Pay attention to keep the basin water clean in hot season, and cut off dead leaves, petioles and pedicels in time after flowering to prevent nutrient consumption and keep the plants beautiful. But if the flowers wither and sink into the water, they must not be cut off, so as to complete the fruiting period. During the growing period, if the growth is not prosperous and the leaves are small and thin, you can bury a little cake fertilizer or urea next to the roots. Water lily is a positive plant, and it needs plenty of sunshine during its growth. If it is maintained in a cool place, the water surface is easy to grow moss, and the plants grow weakly, with only long leaves and no flowers. Generally, water lilies can bloom in potted plants for one year. After flowering, when the leaves wither, the roots should be taken out of the soil and hidden in a greenhouse with water or sand. You can also pour out the basin of water before and after the cold dew festival, cut off dead branches and rotten leaves, and move into an ice-free room for the winter. The next spring, potted again.
Water lilies are vulnerable to aphids and moth water during their growth and development.
(1) aphids. During the growth period of water lily, if there is insufficient light and poor ventilation, it will not only grow weakly, but also be vulnerable to aphids. When pests are found, they can be sprayed with dichlorvos 1200 times water solution or killed with tobacco leaf water (50 grams of tobacco leaves are boiled with 5 kilograms of water).
(2) water lily borer. Water borers, also known as cotton borers, harm the leaves of water lilies with larvae, bite them into two pieces of the same size, and then spin silk to overlap as protective sheaths to live in them. With the help of blades, it can float freely on the water. After protecting the sheath, plant a new sheath. Larvae mostly eat at night. During August-September, the larvae mature, the two leaves often close, and then spin silk to form a white oval cocoon pupa.
Prevention and control methods: ① Catch the larvae floating on the water with nets in time. ② In larval stage, 50% cartap 1000 times solution can be sprayed.
