Red zebrafish is a relatively small tropical fish. But among zebrafish, they are the bigger ones. When they grow up, their body length can reach 4-6 cm. Because of their small size and gentle temperament, they can be raised in multiple tanks or mixed with other small tropical fish. However, the density of farming should not be too high, otherwise they will grow poorly.
The life span of red zebrafish is not very long, generally only 2-3 years. If the breeding environment is suitable, they can live longer, but they can only live for about three years at most, and they will not grow any longer. If the conditions of the breeding environment are poor, the water temperature is very high or there is a lack of food, then they can not grow healthily and their life span will be shortened accordingly.
Want to let red zebrafish grow bigger, should use a larger tank to raise them, to provide them with sufficient growth space. The breeding density should not be too high to avoid hypoxia. It is best to feed them once a day to supplement their nutrition and promote their growth. Don't feed them too much food at a time, lest the leftovers remain in the water and pollute the water. Change the water once a week to keep the water clean. In this way, they can grow bigger when they are in a suitable environment.
