zebrafish in the juvenile stage, the difference between male and female is very small, basically it is difficult to distinguish. After a few months of breeding, they will be mature and it will be easier to distinguish between male and female. Specifically, it can be distinguished from the following aspects:
1. Body size: The body size of male and female fish is similar at the juvenile stage. After they are mature, the size will show the difference. By comparison, the male fish is larger and longer; The female fish is shorter and smaller.
2. Appearance: In addition, it can be judged by their appearance characteristics. If it is a male fish, then their fins are relatively long, the female fish will be relatively small. You can also look at their abdomens during the breeding season. If the female fish, then their abdomen will be relatively large, the male fish abdomen is relatively smooth.
3. Color: You can also see their color. Males are more brightly colored, and their body stripes are more pronounced, but females are duller in color and lighter in stripes.
4. Activity: It can also be judged by activity. The activity of male fish is relatively high, usually more lively and active. You can observe it when you feed, and the male fish are very active when they grab food.
zebrafish male and female can be raised together, generally will not fight with each other. And their habits are basically the same, there is no inconvenience to keep them together. However, we need to pay attention to providing enough food at ordinary times, otherwise the female fish may not be able to compete with the male fish.
