The average life span of traffic light fish is about 2-3 years. Like other small tropical fish, their life span is relatively short. Moreover, they have high requirements on water temperature, water quality and feeding. If they can't guarantee the comfort of their living environment, their life will also be affected. If breeders want to make traffic light fish live longer, they must first ensure that their living environment is stable, so as to avoid environmental mutation causing them to die. Secondly, it is necessary to ensure that they have enough food. If they don't have enough food, it will also affect their physique and life span. Finally, we should check their bodies regularly, and sterilize and disinfect them regularly to avoid getting sick. If the disease is found, it needs timely treatment.

Traffic light fish can reproduce when they are born 6-8 months ago, but in general, try not to let them reproduce when they are just mature. Because they have just matured, their organs are still unstable. In addition, their breeding time is not fixed every year. If the environment is comfortable, they will start breeding from August to October every year. If the environment fails to meet their requirements, they will not reproduce. If breeders want them to breed, they need to adjust their living environment or prepare a separate breeding tank for them.
