金鱼的年龄和辨别方法

金鱼（详细介绍）

家养金鱼的寿命多为4-6年，2-3年是最佳观赏年龄。在这个阶段，金鱼具有明显的特征，身体强壮，可以自由游泳。老年金鱼的年龄为4-6岁。他们的体色正在褪色，他们懒得游泳，食欲减弱，而且非常容易生病。然而，6个月内的金鱼刚刚开始身体发育，品种特征不明显，颜色也不刻板。不良品率很高，且仅限于家庭饲养条件，不易饲养。因此，6-18个月龄的金鱼是最合适的。现阶段，金鱼食欲旺盛，能自由游动，品种特征初步显现，价格合理。它们可以在家里保存大约2年

The age and distinguishing method of goldfish

Goldfish (detailed introduction)

The life span of domestic goldfish is mostly 4-6 years, and 2-3 years is the best viewing age. At this stage, goldfish has obvious characteristics, strong body, and can swim freely. Aged goldfish are aged 4-6 years old. Their body color is fading, they are lazy to swim, their appetite is weakened, and they are very vulnerable to illness. However, goldfish within 6 months have just started their physical development, and the variety characteristics are not obvious, and the color is not stereotyped. The rate of defective products is very high, and it is limited to family breeding conditions, which is not easy to raise. Therefore, goldfish aged 6-18 months is the most suitable. At this stage, goldfish have a strong appetite, can swim freely, and the characteristics of the species are initially shown, and the price is reasonable. They can be kept at home for about 2 years
