Under normal circumstances, the lifespan of elf fish is about 5-6 years, which is relatively long among small fish. They have strong environmental adaptability, but are prone to sudden death when the environment changes suddenly. Therefore, after just placing them in the new fish tank, be sure to take good care of them and give them a suitable environment to prevent them from dying suddenly.

When breeding elf fish, be sure to provide them with a suitable growth surroundings. They are able to eat algae in the tank, so if there is enough algae in the tank or on the tank walls, it's okay to not feed them. But if the tank is relatively clean and lacks food, they should be fed some plant-based feed that can sink to the bottom. lest they starve to death. When breeding, be careful not to change the water temperature too much, otherwise they will be prone to sudden death. It is best to change the water by a third or a quarter each time, so as to avoid sharp changes in the water temperature.
