How to raise fish in a fish tank? Is it good to raise fish in a fish tank?

Choose the right species: because unlike traditional fish tanks, ordinary water tanks can only be observed from above, so it is suitable to raise some fish that look at the back. Feeding density: No matter what container you use to raise fish, you should pay attention to feeding density. Change water regularly: if the water quality deteriorates rapidly, change water every three days, and if the water quality deteriorates slowly, change water once a week. Feeding feed: Fish food has granule and flake, both of which can be used, as long as it is convenient to clean. First, choose the right species to raise fish in the tank. Different from traditional fish tanks, ordinary fish tanks can only be observed from above, so it is suitable for raising some back-looking fish, such as traditional goldfish, koi fish and new-type back-looking herring. These fish are all wide-temperature fish, and it is also suitable to keep them in a tank.

Second, the feeding density No matter what container is used to raise fish, we should pay attention to the feeding density. Under normal circumstances, one centimeter of fish can be raised per liter of water. However, because there is no filtration system in the water tank, oxygen pump is generally not used, so the ability to maintain water quality is weak and the feeding density is small to ensure the breathing and growth of fish.

Third, change the water regularly In order to maintain the water quality, the water tank should be replaced regularly. There is no fixed cycle for changing water, because the size of water tanks is different and the number of fish is different, so the speed of water quality deterioration is different. If the water quality deteriorates rapidly, it should be changed every three days, and if the water quality deteriorates slowly, it can be changed once a week.

Fourth, feeding feed In the daily feeding process, we should also pay attention to feeding feed. Because of different kinds of fish, their eating habits are different, but fish food is usually enough. Fish food is granular and thin, as long as it is easy to clean. Feed it three times a day and eat it within 3-5 minutes each time.
