When breeding two-line fish, you can consider the problem of mixed culture, mixed with other species of fish, the ornamental effect is good. However, it should be noted that not all varieties can be mixed. There are many factors that need to be paid attention to when choosing polyculture fish.
First of all, we need to consider the size of the fish. The double line fish is an ornamental fish. Its body length can reach 35 centimeters. It cannot be mixed with fish that are too small. Otherwise, they may bully fish that are smaller than them. Of course, you can't choose a fish that's too big, or you'll be bullied by a two-line fish. In addition, from the point of view of habits, double-line fish belongs to a tropical fish, which requires higher water temperature, it is better to choose fish with similar habits and characteristics to mix with them, otherwise it is not easy to control the surrounding factors. Considering the above factors, you can choose embroidered fish, lucky fish, crucian carp and other fish to mix with them. In the process of polyculture, space and feed must be sufficient.
Choose with double line fish mixed culture species, try not to choose arowana. From the personality point of view, the character of arowana is relatively fierce, territorial awareness is relatively strong, and grabbing food will be more active. Moreover, from the point of view of size, the size of arowana is generally relatively large, some arowana length can reach 60 centimeters or more, but the size of double-lined fish is only about 35 centimeters, the difference in size is relatively large, so arowana is not suitable. Of course, if you have to be mixed, you also need to choose a similar size, otherwise the two-line fish may be eaten by arowana.
