One-eyebrow mermaid is a common ornamental fish, and it is necessary to know their body shape before raising them. They are not too big or too small, and they are medium-sized fish. They can generally grow to 15-20 cm. Among them, those who live in the wild are relatively large, mainly because the water quality in the wild is more suitable for their growth. Moreover, the living environment in the wild is even worse, and the fish that can survive have strong resistance. In domestic breeding, they are relatively small. Especially if the feeding method is inappropriate, it will seriously affect their growth.

The growth rate of the one-eyebrow mermaid is affected by its own conditions and external conditions. The influence of self-condition is the main one, which is caused by the defect of gene. Some fish have physical defects when they are born, grow slowly and grow little. This situation can be avoided by avoiding inbreeding during breeding.

The influence of external conditions mainly includes living space, water temperature, feeding and other factors, which can change their growth rate. Therefore, when raising them, we must first ensure that the density of raising them is not too high. Secondly, it is necessary to ensure that the water temperature cannot change too much, and it is generally controlled at about 25 ℃. Finally, make sure that the feeding amount is not too large, and disinfect the food. Only in this way can they grow quickly.
