1, density: in the breeding of lion head goldfish, the first thing to pay attention to is the density. If too many fish are bred in too small a space, then they may die due to lack of oxygen or insufficient food. The number of fish to be bred needs to be adjusted according to the size of the tank, for example, if you use a tank with a length of 40, a width of 25 and a height of 30 centimeters, you can breed 4-6 small fish of 4-6 centimeters.
2, feeding: feeding the lionhead goldfish is also more important. You should avoid feeding them some poor quality fish feed, or they will suffer from malnutrition, and may even get sick and die. Generally speaking, it is more appropriate to feed some animal feed. For example, earthworms and green worms are OK. In addition, you can also feed some white sesame seeds, which are also better digested by lionhead goldfish.
3, water change: breeding lionhead goldfish, you also have to regularly change the water in the tank. However, the amount of water changed each time can not be too much, control in a quarter or one-third is the best. You can use water that has been exposed to the sun to change the water, so that it is not easy to cause damage to the goldfish. When changing water, the new water should be added slowly, otherwise it may lead to a drastic change in water temperature, and the lion's head goldfish is not easy to adapt.
