What should I pay attention to when raising goldfish?
2. Goldfish is a fish with high oxygen consumption, so it is very necessary to ensure sufficient oxygen in the water. Buy an oxygen bottle.
3, goldfish eat more Dora, so the water is particularly easy to get dirty. It is very important to have a strong enough filtration system. Of course, some people will consider economic issues, so they don't want to use filters. Of course, but this person will be affected. If the fish tank is small, you should pump the bottom every day. If the fish tank is big, you should pump the bottom every other day, because fish excrement will produce a kind of fish.
4. Change the water regularly. What I just said was to draw the bottom. The amount of water changed by pumping is usually only one tenth to one twentieth. The amount of water changed in this way is not enough It is necessary to change water regularly on a larger scale: change one-fifth of the water in summer for three to five days and one-third in winter for one or two weeks.
5. Feed regularly and quantitatively. Goldfish is a kind of fish that can never be satisfied with food. If they are healthy, you can say when you feed them, when they eat, and how much you feed them until they die. Therefore, it is very important to control the feeding frequency and quantity artificially. It's easy to eat once or twice a day for 3 to 5 minutes each time. The inedible food should be fished out in time to avoid affecting the water quality. More importantly, especially the fish you just bought, you can eat it in 1 minute, 2 minutes and 3 minutes until you can feed it normally. If you don't pay attention to this, goldfish can easily get enteritis.
6. Keep the water temperature constant. As long as the water temperature rises or falls slowly, the goldfish can survive in the water temperature of 0-39℃. However, if the water temperature changes suddenly, the goldfish will get sick, ranging from a cold to congestion, or even die. So observe the weather at ordinary times, and change the water. Try to control the temperature difference between the new water and the old water at plus or minus 2 degrees. It is best not to deteriorate at one time or the new water is one degree higher than the old water. Pay attention.
7, do a good job in disease prevention measures, fish farming should focus on prevention, do not wait until you are sick to treat, generally it is too late. Usually, one thousandth of salt should be put into the water regularly, not edible salt, but special salt for fish farming, which is sold in the fish market. When you see that there is something wrong with the fish, but you can't tell the reason, increase the quantity to three thousandths, and then increase the frequency of changing water to raise the water temperature to 2 to 3 degrees of the original water temperature.
8. Disinfect fishing gear. Many people who have just started to raise fish have a question. Why did the fish you just bought die in a few days? In fact, they don't know that the new fish tank contains many substances harmful to fish. If these substances are not removed, buying more fish will only lead to death. How do you get there? This is the so-called open tank. Before buying fish, wash the fish tank with high concentration potassium permanganate, and then rinse it with clear water. Soak the whole fish tank with low concentration potassium permanganate for two days, then rinse it with clear water, then fill the fish tank with fresh water and let it stand for two days. If possible, add nitrifying bacteria. If not, forget it. After 24 hours, put four or five small fish in the tank, and after three days, you can put your beloved fish in. This is a very troublesome but safe way. Of course, in addition to opening the tank, it is also important to disinfect fishing gear at ordinary times. As long as the fishing gear that has caught sick fish is disinfected with high concentration potassium permanganate.
9. Control the water color of fish farming. Many people like to make water clear. Of course, clear water is definitely a kind of enjoyment in visual effect. However, fish raised with clean water are most likely to get sick. Therefore, it is not recommended for novices to raise fish with clear water. It is best to raise fish in light green water, in which fish will hardly get sick. There is also a kind of green water, which can make goldfish more colorful.
It seems that's all. It looks complicated, but it's not difficult. As long as you really want to raise fish well and really like raising fish, it's easy to do. I wish you success!
Another thing I forgot to say is that it is best not to use tap water directly to raise goldfish, because water contains a lot of chlorine, which will cause harm to fish. You need to pump tap water, let it stand for two days or expose it to the sun for one day before you can use it. Of course, for strong big fish, it doesn't matter much if a small amount of water is changed and tap water is used directly. It is better to treat the water.
