The life span of zebrafish culture is mainly affected by culture factors. Usually, the life span of zebrafish is about 2-3 years, which refers to normal feeding, excluding the life span under the conditions of infection and abnormal death during feeding. Of course, if diseases are difficult to find in the breeding process, they will generally die directly and cannot be treated. Therefore, in order to live a long life, we should try our best to avoid diseases in the breeding process of zebrafish.

Besides diseases, accidental death of zebrafish, such as being swallowed by other fish, death caused by drastic fluctuation of water temperature, etc., may all lead to the slow service life of zebrafish, so the life of zebrafish is not certain, and it is mainly related to the culture method. Although the life of zebrafish is 2-3 years, few people can really raise it for 2-3 years. If you want your zebra fish to live longer, you should pay attention to the following three points:

1. First, raise the water well before entering the fish to avoid the death of the zebra fish due to the inadaptability to the environment;

2. Secondly, the water temperature and water quality should be maintained. The temperature of zebrafish breeding should be kept at 25-26℃ to keep the water quality clear and transparent.

3. Feeding is the main reason that affects the life span of zebrafish, so breeders must pay attention to it. Safe food is feed, and the feed should be placed in a dry and cool place.
