The traffic light fish is tropical fish. When breeding them, it is necessary to maintain a proper water temperature, preferably between 22 and 26 degrees. When changing water, pay attention to the temperature difference between the temperature of new water and the temperature of old water, which can easily cause traffic light fish to catch a cold.

The water temperature for breeding traffic light fish should be controlled between 22 degrees and 26 degrees. If the water temperature is too low, you need to use a heating rod. If the water temperature can be controlled within a suitable range, the heating rod may not be used.

1. Water temperature: During the breeding period, whether in winter or summer, it is necessary to control the water temperature within the above suitable water temperature range to avoid high and low temperatures. The temperature goes up and down, and the traffic light fish get sick easily.

2. Illumination: Traffic light fish are tropical fish, which need illumination. During the breeding period, it is necessary to ensure that the daily illumination time cannot be less than four hours. If you can't accept natural illumination, you can make up the light artificially, for example, you can use LED lights to make up the light.
