1. Choosing goldfish: If breeders want to raise goldfish better, they should pay attention when selecting goldfish. It is best for breeders to buy goldfish every autumn, because goldfish are the strongest at this time. When breeders choose, it is best to choose some fish with flexible swimming and strong physique, so that later breeding can be relatively simple.

2, environmental stability: To breed goldfish, breeders should keep the environment stable. Although they have low requirements for the environment, they are sensitive to environmental fluctuations. When breeding, they can grow well as long as the breeder keeps the environment stable.

3. Regular disinfection: Breeders should also sterilize them regularly, which can reduce the breeding of bacteria, reduce the probability of illness, prolong the life of goldfish and strengthen their physique.

1. Reasonable feeding: goldfish do not feel full, and if they are fed too much food, they will easily be supported to death. Even if you don't die, you may have indigestion and gastrointestinal diseases. Breeders need to feed them reasonably, so as to reduce the incidence of illness.

2. Regular illumination: Breeders should also give goldfish regular sunshine, which can not only sterilize and disinfect, but also improve their resistance and immunity, making goldfish stronger.
