The traffic light fish will appear the behavior of enclosing the land before giving birth to small fish. Two fish will occupy the side of the water grass and do not allow other fish to approach. In addition, the shoulders of their dorsal and anal fins turn black. The belly will be round and the anal fin will be fan-shaped.
The traffic light fish can breed once a year, and the best breeding period is from August to October every year. When the abdomen of the female fish expands, it is fed separately from the male fish, and then paired into the box after feeding enough food.
1. Water temperature: The water temperature should be kept at about 25 degrees during reproduction of traffic light fish. If the temperature is too high or too low, the reproduction effect will be affected.
2. Environment: When the fish are breeding at the traffic lights, the surrounding environment should be absolutely quiet. Because traffic light fish are particularly afraid of disturbing when breeding, if there is noise, it is likely to affect their health.
3. Feeding: Before the production, the traffic light fish should be properly fed to avoid the sudden situation caused by insufficient physical strength during the production. When feeding, animal feed with sufficient nutrients can be selected. For example, red nematodes, small earthworms, small shrimps and so on. It should be noted that not feeding too much, feeding too much is counterproductive, will affect the production of traffic light fish.
