Female snakehead will gradually weaken during reproduction, and her eyesight will also be affected. They can't see at this time, so they can't eat.
At this time, a part of the hatched little black fish will swim into the mother's mouth and take the initiative to serve as her mother's food until her mother regains her sight.
According to this habit, humans call it dutiful fish.
First, why is snakehead called filial fish? Snakehead is relatively common in China and widely distributed in freshwater basins.
The name snakehead is quite common, but they also have some other names, such as "dutiful fish", which has a lot to do with the habits and characteristics of snakehead.
During the breeding process, the female snakehead will gradually weaken, and her eyesight will be affected, and even she will be blind directly.
Therefore, the female snakehead in this state cannot continue to eat.
And some of the little black fish hatched by it will swim into the mother's mouth as its food to repay her.
After the female snakehead regains her sight, she will always turn around her original position, as if she were paying homage to mankind.
Therefore, according to this habit, humans call snakehead a dutiful son fish.
But the little black fish is not filial subjectively, which is only inferred by human behavior.
In fact, this is only a very natural phenomenon in the process of biological reproduction, and human beings pin their good wishes on it.
Second, why is snakehead called God of Wealth? As mentioned above, snakeheads have some nicknames. In addition to filial piety, there is also the god of wealth fish.
When people give them this name, it is related to their appearance and their nutritional value.
From the appearance characteristics, the stripes on the snake head make it look very like ancient copper coins; From the point of nutritional value, snakehead is a kind of fish with very rich nutrition, and its price is relatively expensive.
Therefore, snakehead is called wealth fish.
In fact, snakehead is helpful to family feng shui in Feng Shui, so some people keep it at home.
