How long can map fish live without oxygen? What should we pay attention to when raising them?

Map fish can live for about a day without oxygen. If they are extremely deprived of oxygen, they can only last for a few hours. Oxygen is necessary for them to carry out life activities. If the breeding density is relatively high and their physique is not very strong, then they must be given oxygen, otherwise they will soon die. But if the feeding density is very small, only 1-2, then in the premise of ensuring timely change of water, they can also not be oxygenated.

1. How long

can a map fish live without oxygen? Normally, if a map fish lives in an anoxic environment, it will die in less than a day. This kind of fish requires a relatively high amount of oxygen, so we should pay attention to giving them oxygen continuously to avoid the occurrence of hypoxia.

2. What should we pay attention to when raising map fish?

We should pay attention to the following points when raising map fish:

1. Adequate space for activities: When choosing a fish tank, we must choose a fish tank with a larger space to leave them enough space for activities.

2. Water quality: Keep the water clean during feeding, and clean the sundries in the fish tank in time to avoid water pollution.

3. Water temperature and oxygen: Map fish belong to tropical ornamental fish. When raising them, the water temperature should be controlled at about 25 degrees. In addition, attention should be paid to oxygenation to avoid hypoxia caused by too high water temperature.

4. Light: Give them two hours of light every day, but avoid direct sunlight.

5. Food: Map fish is a carnivorous animal. When raising them, we should pay attention to feeding them more small fish and shrimps to avoid too single food.
