? Guppies are only suitable for slow-moving water flow. If the current is too fast, it will affect their development. Whether they need oxygen when they sleep depends on how much water flows when they sleep and whether it will affect their rest. If oxygenation will cause the current to be faster, don't oxygenate it while it sleeps, because the guppy is very sensitive to the change of the current, and the larger current will affect its rest. But if only the water flow on the surface of the fish tank is relatively large, it is no problem. Because the main activity area of guppies is in the middle of the fish tank, they will sleep at the bottom of the fish tank. Just having water on the surface doesn't affect them. In addition, if the power of the oxygen pump is not very large, the oxygen will not cause excessive water flow, then they can also be oxygenated while sleeping.
, guppies do not need 24 hours of oxygen, mainly depends on the density of feeding. If you simply raise a few, you don't need to use oxygen, because the oxygen consumption of guppies is very small, and there is no need to use oxygen. But if the number of breeding is relatively large, it needs to be oxygenated occasionally during the day. Oxygen should pay attention to avoid the time when guppies eat, because when oxygen flows too much, it will affect the eating of guppies. It is no problem to avoid oxygen at this time.
