I want to raise two fish at home, but I can't keep them alive. I bought them several times, but they all died soon after I bought them. What's the situation? Xiaobian will tell you the answer~
The reason why the little goldfish died in the afternoon
It's not a good choice to raise goldfish in summer, because goldfish is a kind of high oxygen fish, and the water temperature is high in summer, the bacteria propagate too fast, and it's extremely easy to get sick. The best temperature for goldfish is about 18-22 & deg;, and it is enough to keep this temperature and give him enough space. The basic knowledge of fish culture, fish culture is to raise water, water raised fish generally no problem. Generally recommended tap water, to sun for two days, the time is too short, there will be bleaching powder in the water, toxic to fish. It's not good to have too many bacteria in the water for too long. It's usually about two days. I don't know if the fish got sick when you bought it. Also, if the owner's fish tank is within 30cm and there is no filtration or oxygen enrichment equipment, it is recommended to only raise two or three goldfish of 3-5cm. If there is too much oxygen in the water, it is easy to die of hypoxia. Add some coarse salt in the water for sterilization. Often observe goldfish, if the fish are breathing on the surface of the water can be identified as hypoxia. Change 1 / 3 of the water (also dried), or reduce the number of fish. Change the water frequently. Generally, change 1 / 3 of the water in two days. It can be changed frequently, but not for a long time. Too long, the nitrite in the water will destroy your fish. Goldfish have a lot of food, fish, insects or feed. As long as you grasp a certain scale, you can eat less and eat more. Generally, it's better to feed the fish in two minutes at a time.
How to choose little goldfish
It's time to choose the little goldfish. First of all, we should grasp the best time to select small goldfish. The first time to select a small goldfish was about 15 days after it hatched. When the young goldfish grow to about 1.5 cm, you can change the water for the small goldfish, and then select them. This selection of small goldfish, to be healthy. Will be a single tail and other unhealthy goldfish out of all.
The second time to choose a small goldfish is about one month after it hatches. At this time, the goldfish has grown to about 2 cm, and the fins of the whole body have developed completely, and the shape is obvious. Therefore, at this time the selection of small goldfish should also choose healthy, single tail, partial tail, dorsal fin incomplete small goldfish out, and all out.
The third time to select a small goldfish was about two months after the goldfish hatched. At this time, the small goldfish has basically formed its shape, and its body has been fully developed. The characteristics of all parts of the body and the fins have also developed significantly. At this time, it is necessary to select the goldfish seedlings with proper and symmetrical body shape, four open tails and obvious excellent characters, but the goldfish with physical defects can not be selected.
We choose small goldfish to go through layer upon layer screening, leaving the beautiful and healthy little goldfish behind. For the novice of raising small goldfish, when selecting, you must carefully distinguish the body condition of goldfish. If you can't master the method of distinguishing, you can ask an experienced friend to teach you some feeding methods of small goldfish, so as to ensure that you can select healthy and beautiful small goldfish.
Methods of changing water for raising small goldfish
Just after hatching, small goldfish will be separated from big goldfish to prevent being eaten by big goldfish. Generally, small goldfish stay in the original tank, and big goldfish move to other containers. Don't change the water frequently at this time. The little goldfish is just born and has a weak ability to adapt to the environment. During this period, put in the air pump for oxygen to maintain the oxygen content in the water. After feeding the first meal 3-5 days later, change the water for the little goldfish the next day. Transfer the little goldfish to the new sink with a small spoon. The water temperature must be consistent so that the little goldfish can adapt. This completes the first water change. If the tank is large enough, Water Goblins can be put in to aerate and filter with minimal water flow.
After that, there will be some repetitive movements. Transfer the fish once every 15 days. All movements should be gentle. In about two months, the size of the fish is about 1.5cm. Every time before changing water, be sure to use potassium permanganate to disinfect and rinse. The temperature of water change should be consistent.
