1, pick a good fish
If you want to raise them well, you must choose carefully, which is the only shortcut to raise them well. Be sure to choose those that look symmetrical and slightly fat. Such small fish are in good health. Don't choose those that are overweight. They may be sick fish, as long as they are thin.
2, less fish farming
If the water quality is good, it is necessary to raise less and not be greedy. No matter what kind of ornamental fish you breed, you can't be greedy. If we raise more, the water quality will be difficult to maintain and the little goldfish will die of lack of oxygen. For example, a small cylinder with a diameter of 30 cm and a height of 15 cm, it is very good for us to raise two or three grass gold pieces with a length of four or five cm.
3, the choice of fish tank
For this kind of grass goldfish, the choice of fish tank is very important, and the square tank is the best. If you feel unnecessary, you must choose a fish tank with a round mouth and a relatively low water level, so that the dissolved oxygen in the water will be rich. Like some special-shaped fish tanks, such as flat-edged, cylindrical and grass goldfish, they can't be raised, and almost all of them lack oxygen.
Step 4 change water
Then there is the problem of changing water. Every time you change the water, you must dry it. The water temperature should be the same as that in the fish tank. Just change the water by a third at most. If we have two small fish tanks, we can dry tap water for more than a week, or we can exchange it between the two fish tanks. Even if all the water is changed, it will be fine, and it can be raised well, but this method is only suitable for grass goldfish.
5. Water temperature
Be sure to pay attention to the water temperature when changing water. Generally speaking, the difference should not be too much, preferably within two or three degrees. Another problem is that the fish tank is too small to maintain the water temperature for a long time. We must not put the fish tank indoors where it is overheated or the temperature fluctuates. Generally speaking, if the fish tank is too small, we will adopt the principle of low temperature but not high.
Step 6: Feed.
Proper feeding will make the ornamental fish healthy. Under the condition of controllable water quality and density, we can feed it once a day and eat it within three minutes each time. It is best to choose ordinary pellet feed for fish food. Be sure to feed less every time, and pump the bottom to change water after two or three days.
