Hello friend ~ usually is not big The reason is still related to the limitations of the water body ordinary home breeding goldfish are usually in aquariums and small fish ponds, the narrow body of water to limit the size of the adult goldfish, so usually the goldfish can not grow too big Spring a centimeter or so of the goldfish fry are usually kept until the fall can be opened up to ten centimeters or so, and then perhaps also grow, but in general will not have too much growth. The big individual goldfish commonly seen in the market are kept in fishponds without the limitation of environment size, so they grow faster and become bigger, but they are only as big as an adult carp, usually after 2 years, they won't grow anymore, so if the food supply of the juvenile goldfish is not enough, they won't grow any more, we usually call this kind of fish "old man fish", which means it won't grow anymore. The first thing you need to do is to get a good deal of money from the bank to pay your bills.
