? When the environment is very suitable for goldfish, goldfish will grow very fast. The growth rate of goldfish has a great relationship with the growth environment of goldfish. Water temperature, water quality, feeding and other factors are very important. The size of the water body is particularly important, not only affecting the growth rate of goldfish, but also affecting the final size of goldfish. For example, goldfish growing in a fish tank are basically smaller than those in a pool. Grass goldfish, for example, can generally grow to 10-20 centimeters in a fish tank, but if they grow in a pool, they can grow up to 40 centimeters, and generally to 20-30 centimeters.
a month. The growth rate of goldfish is not only closely related to the environment, but also to the species of goldfish. Common species of goldfish can normally grow about 8 centimeters a year at the age of vigorous growth, and less than 1 centimeter a month on average. Some species of goldfish, such as gilded goldfish, can grow about 12 centimeters a year, and the growth rate is much faster. The final size of different species of goldfish is also very different, such as grass goldfish in the fish tank can generally grow to 10-20 cm, dragon goldfish can generally grow to 15-20 cm, egg goldfish will be shorter, usually only grow to 10-15 cm.
