The main reason for the death of small fish is the poor water quality. Fish must first raise water, generally using tap water, in order to dechlorinate water, need to be aired a few days in advance, so that water can be used for fish farming. In addition, water should be changed regularly to keep the water clean and hygienic, and a quarter of it should be changed each time.
Raising small fish must provide adequate nutrition, because at this time their body energy storage is still relatively small, so hunger tolerance is not strong, if hungry for a long time, it is easy to starve to death. Usually feed two to three times a day, but each time the amount of food should not be too large, if the appetite is not strong, you need to stop feeding.
The temperature of raising small fish is very important, because their adaptability is not strong at this time, so we must pay attention to temperature control, the temperature can not change too much. If it is a wide range of temperature fish, the temperature requirements are slightly lower, do not need to keep warm, if it is tropical fish, the temperature should be controlled between 20-30 degrees Celsius.
Fish in the absence of oxygen when there are often some signs, as long as the timely oxygen is no problem, but the fish in the absence of oxygen, it is easy to die. It usually takes 2-4 hours to open the oxygen pump every day, and 2 hours more in summer.
