One-eyebrow mermaid can be mixed with guppish, which can be seen from three aspects. First of all, from the character point of view, they are gentle fish and will not take the initiative to attack other fish. In polyculture, we should pay attention not to have a big difference in body size. If the difference is too big, the big fish will bully the small fish and rob the small fish of food, which will affect the growth and development of the small fish. Secondly, from the living environment, they are all freshwater fish. The living environment is not much different, and they are all suitable for living in weakly alkaline hard water with a temperature of 20-26 ℃. When raising them, they will not lose sight of one thing and the other. Finally. They are common fish with beautiful colors, and the ornamental effect is very good when they are mixed.

In family feeding, the common feeding tanks are square and round. Compared with round fish tanks, square fish tanks are more suitable for raising them. This is mainly because the round fish tank will enlarge the scene in the tank and affect the viewing effect. The square fish tank gives people an intuitive viewing effect. When choosing a fish tank size, you cannot choose a fish tank that is too small. When they are adults, most of them can grow to 14-15 cm, and the length and width of the selected fish tank are at least about 20 cm. If it is too small, it will affect their growth and development.
