If there is plenty of room for zebrafish to grow, and the breeder also installs a circulating filtration system for them, it will not affect their normal life without oxygen. Because there is enough space, there is enough dissolved oxygen in water. In addition, the circulating filtration system can also provide a small amount of oxygen in the water, so zebrafish can live normally without oxygen. If zebrafish live in high density and their breeders don't take oxygen, they can last for 3-5 days at most.
How long can zebrafish live without oxygen 1. How long can zebrafish live without oxygen

How long can zebrafish live without oxygen depends on their growing environment. If zebrafish live in sufficient space and large water body, the breeder will not give them oxygen, which will generally not affect their normal life. In addition, many breeders will install a circulating filtration system, which can also provide oxygen to the water, so they can grow well without being oxygenated by breeders.

If zebrafish live in high density and the water quality is unstable. If the breeder doesn't give them oxygen, they will die for 3-5 days at most. Because zebrafish have a high demand for oxygen, if they can't guarantee sufficient oxygen, they will die.

2. How long is the life span of zebrafish

Zebrafish can live for 2-3 years, and their life span is relatively short compared with other fish. In addition, the environment in which they grow will also have a certain impact on their life span. If they grow in a comfortable environment and are fed sufficient food and nutrition, their life span can reach about 3 years.

If they grow in an unstable environment and are not fed enough food, their life span is generally only 1-2 years. In addition, diseases can also affect their life span. If zebrafish get sick frequently, their life span will be shorter. If their physique is good, their life span can reach 3 years.
