If you want to feed wild small fish, you should first pay attention to feeding. If the newly fished small fish has not been born for a long time, you need to feed it with migratory water. The water contains a large number of microorganisms, which is very suitable for feeding. If you can't get the water, you can feed it a little cooked egg yolk, but be sure to gently twist a little into the water, feeding more easy to change the water.
No matter what kind of fish you raise, you should change the water regularly, and so should the small wild fish. Usually, tap water is also used to raise this kind of fish, but in order to remove chlorine, it is better to dry it a few days in advance, so that the water can be used safely. Usually change the water once a week, do not change too much each time, change a quarter of the total amount is enough.
Fish tank will become dirty for a long time, this time must pay attention to cleaning. When cleaning the fish tank, the small fish need to be fished out first, and then the algae and scale on the wall of the fish tank are scraped off by using other tools such as an algae scraping knife, and after the cleaning is completed, the water is released again for fish culture.
Because wild small fish originally live in natural water, dissolved oxygen is often relatively sufficient. However, if they are raised at home, because there is not much water, oxygen may not be enough. They need to be oxygenated regularly to keep the dissolved oxygen in the water sufficient, which is very important for the health of the fish.
