? Small fish should feed plankton commonly, also can cast feed cooked egg yolk to give it to eat. It should be noted that newly hatched fish do not need to be fed, at this time they can also absorb their own yolk sac, until the next day before they need to prepare to eat. It is better to feed the larvae with water, which is not only safe, but also nutritious. You can also choose to feed egg yolk, but only a little light twist, too much water is easy to spoil.
1, feeding: The most important thing to raise small fish is feeding, feeding more or less is not good, food is also relatively limited, hatched fish can be fed with water or cooked egg yolk, a little bigger can be fed with shrimp, as it grows, it is also necessary to gradually change the feed, so as to ensure that the fish are full. At the same time, it is more nutritious.
2. Change the water: Small fish do not need to change the water for a week after hatching, and they can change the water for the first time after a week. If the water quality fluctuates, it will have a certain impact on the health of the fish, and the water can not be changed more, about one fifth of each time. In addition, because the water needs to be pumped first, we must be careful not to pump the fish out.
3. Temperature: For small fish, temperature is particularly critical. Once it changes, it can easily lead to their death. Heating rods are usually prepared to keep the water temperature constant. Generally, compared with adult fish, small fish require 1-2 degrees higher water temperature.
