Thai fighting fish (certain introduction)
Regarding some breeding For fish people, it is difficult to accurately determine the true age of fish. Due to the different body shapes and growth rates of fish, it is very important for new aquarists to understand their age of opportunity if they want to choose healthy and high-quality reference fish.
To accurately infer the age of a fish, you might as well observe the changes in their scales. In the first year of life, most fish will be covered with tiny scales. These scales will have many flakes of different sizes. At first glance, they look like a cone with the top cut off. . It is thick in the center and thin at the edges. The top layer is the smallest, but it is the oldest; the bottom layer is the largest, but it is the youngest.
When the fish is young, the scales will look tender and small, and the number will be relatively small. As the fish gradually grows, new thin sections are formed on its upper layer. As the age of the fish decreases, the number of lamellae also continues to decrease. Therefore, the older the fish, the scales will be richer, crisper, and larger.
It turns out that besides looking at fish scales, there are other ways to check the age of fish. We know that some fish have scales, but there are also many fish that do not have scales. Therefore, we can judge the age of the fish by looking at its spine, gill covers, otoliths, etc. Naturally, the method of inference is similar to that of observing fish scales, both of which use the "annual rings" and "characteristics" produced by fish over time to determine the age of the fish.
