First observe the thickness of the scales, then you can also observe the growth wheel of the goldfish scales, then count the number of goldfish scales, and observe the hardness and color of the scales.

The age of a goldfish can be judged from the state of its scales. Next, Xiaobian will explain in detail how to judge the size of fish by looking at fish scales.

Details

01

Scale thickness

The thickness of the first look at the goldfish in the fish scales, if fish scales is very thin, explain the goldfish should be just a newborn, the thicker the goldfish scales, is that the age of the goldfish.

02

Fish scale growth wheel

There will be growth wheels on the scales of goldfish, but because the growth wheel is relatively small, it needs to be observed with the help of a microscope, so we can use a microscope to observe the scales of goldfish, in general, there are several deeper lines, indicating how old the goldfish is.

03

Number of scales

The scales of the young goldfish will be smaller and the number will be smaller. As the goldfish grows up, new scales will appear on the surface of the goldfish, so the more the scales are, the older the goldfish will be.

04

Fish scale color

Then observe the color of the fish scales, if the color is more transparent, it shows that the goldfish is relatively young.

05

Scale hardness

Finally, observe the scale hardness of goldfish. Generally speaking, the older the goldfish is, the harder the scale will be.
