Under normal circumstances, goldfish generally live to 6 or 7 years old. If carefully fed, you can live to more than ten years. How long goldfish can live mainly depends on the feeding method. Change water regularly, eat a balanced and healthy diet, and make them live comfortably and healthily, and their life span will naturally be prolonged a lot. Feed regularly, pay attention to the nutritional collocation of feeding food, and adjust the water quality and temperature in time to make them live better. The life of goldfish in spacious and clean environment must be long. Although this fish can adapt to a wide range of temperatures, they will live better at a stable and suitable water temperature. Proper sun exposure is also beneficial to prolong their life span.

First, prepare a larger fish tank, and the spacious living space will make them feel more comfortable. Moreover, if the breeding density is small, the oxygen content of the water in the fish tank will be higher, so there is no need to worry about lack of oxygen. Changing water frequently will shorten their lives, but the cleanliness of water quality is also very important. Therefore, when feeding, we should pay attention to the bait chosen as far as possible not to pollute the water quality, and the feeding amount should be fixed, just when they can eat enough, it will not affect the water quality. Pay attention to clean up food residues and their excrement in time after feeding. Secondly, fish tanks should be placed in the sun, and more sunshine is beneficial to prolong their lives, but at the same time, the water temperature should be fixed, not too high or too low.
