can arowana live without oxygen? If arowana does not have oxygen, it can persist for 12-24 hours, but the time they persist is not necessarily the same under different feeding conditions. Normally, if there is enough space and the water quality is good, they can last for a day. If the breeding density is high and the water quality is poor, the arowana can only last for a few hours. Although arowana is not a fish with high oxygen consumption, if the oxygen stops suddenly, the breeder can change a small amount of water to increase the dissolved oxygen in the water.
can arowana live without changing water? Compared with other fish, arowana is a kind of fish that is more difficult to raise, and it has higher requirements for water quality. If there is a circulating filtration system and oxygenation system in the fish tank where they are raised, they can persist for 2-4 weeks without changing water. If there is no filtration system, but there is an aeration system, it can only last for 1-2 weeks.
If there is no equipment in the tank and the breeder does not change the water, they can only last for one week. Because they can't accept too bad water quality, and they are sensitive to changes in the environment, if the environment in the fish tank becomes worse, they will become weaker and weaker until they die. Arowana is more delicate, breeders in the breeding process had better pay attention to the temperature difference and environmental changes are not too big.
