1, fish tank: First of all, pay attention to the volume of the fish tank, if the number of goldfish is relatively large, then can not choose too small fish tank. If the fish tank is too small and the goldfish are very dense, it will easily lead to poor water quality, less oxygen in the water, and goldfish are very easy to die. Generally speaking, if the water capacity of the fish tank is about 100 liters, it can accommodate three fish of about 10 centimeters and eight fish of 5-6 centimeters.
2, change the water: breeding goldfish also have to change the water regularly. Water quality is very important, if just from the tap on the water, it is best not to use directly, because it contains more chlorine. It is best to use it after two or three days in the sun. Don't change too much water each time, otherwise it will easily lead to the death of goldfish.
3, lighting: Aquarium can be placed in a number of aquarium lights, but for the newly bought goldfish, the light stick on the time not too long, or they easily frightened, death.
4. Feeding: Feeding goldfish is also an important aspect of breeding. You can feed it once or twice a day, but not more than twice a day. The amount of each feeding also need special attention, in 5-10 minutes to eat is the most appropriate, do not feed too much at a time. In addition, in winter, if the temperature is relatively low, then the amount of feeding should be reduced accordingly, not too much.
Whether goldfish need to be oxygenated depends mainly on the breeding density. If the breeding density is not high and the dissolved oxygen in the water is enough for them to survive, then they do not need to be oxygenated. But if there are more goldfish in the water, then the dissolved oxygen in the water will be insufficient, it is necessary to oxygenate, in order to avoid their lack of oxygen.
