Clownfish is a common ornamental fish because of its beautiful appearance. Compared with other fish, they have a longer life span. In the natural state, they grow in the ocean, and clownfish living in the ocean have a relatively long life span, and most of them can live for 10-12 years. But when the environment is polluted, their life span will be shortened. If they are raised in families, their life span is not so long, and they can only live for about 6-7 years. This is mainly because they are a kind of saltwater fish. In daily feeding, the amount of salt added to the water is easy to grasp. Adding more or less will affect the osmotic pressure in their bodies, thus affecting their survival. In addition, if the feeding is unreasonable, it will also affect their life span.

Clownfish is a relatively small fish, and its body length is affected by many factors in adulthood. The most important one is the living environment. If they grow in the wild, as long as the external environment is not polluted, most of them can grow to about 11 cm. If it is raised in families, clownfish will not reach this length. Their body resistance is relatively weak, and their external influence is far greater than that of survival in the wild. For example, inappropriate factors such as water temperature, water quality and feeding conditions will affect their growth and development. Most of them can only grow to about 6-7 cm. Therefore, when raising, we should try our best to provide them with a suitable environment.
