The first step in raising ornamental fish is to open the tank. Opening the tank is to make the new tank, which was originally not suitable for raising fish, become able to raise fish. The steps of opening the tank are very tedious, and if one step is not done well, it will lead to the failure of opening the tank, so that the fish raised will not live long. Usually, the tank needs to be disinfected first, then washed several times, and then injected water into it, after which water should be raised, until the water is well raised, fish can be released.
Fish cannot live without water, and the quality of water also determines their survival. If the water quality is too poor, the fish will die soon after being raised. Usually, filters are installed in fish tanks, which can greatly delay the deterioration of water quality. In addition, the water in the fish tank should be changed regularly. If you have a filter, you can change the water once half a month, and if you don't have a filter, you will have it once a week.
Fish farming needs to feed feed, but too much feed is not enough, fish eat too much every day, easy to suffer from gastroenteritis, a long time will die. Feeding fish should first choose a good feed, first of all, delicious, the size is also appropriate, can supplement a variety of nutrients. Some fish need to be fed a little live bait, which helps the body color. Feeding must be timed and quantitative, feeding to 7 or 8 points each time.
The size of the fish tank determines how many fish can be raised. If we blindly raise more fish, it will accelerate the deterioration of water quality, and will also lead to lack of oxygen in the water body, thus causing the death of fish. Therefore, it is necessary to reduce the number of aquaculture, control the density of aquaculture, or change a larger fish tank, in which an oxygen pump should be installed to ensure adequate oxygen in the water body.
