of oxygen? If the flow of the oxygen pump is small, they will not be afraid, because they can move freely in the flow, and the small flow will not affect their rest and normal activities, so they are not afraid of the small flow.
If the flow of oxygen is large, they will be afraid. Because the current is too strong, it will affect their normal activities, and the current may make them unable to control their bodies, so the current is too strong, they will have fear. When raising guppies, there is no need to turn on more oxygen, because their demand for oxygen is not high, and more oxygen will affect their normal life and rest.
guppies? Guppies are suitable for raising in relatively static environment, and can also be raised in slow-flowing water. Because they live in the slow flow in their native place, if the current is too strong, it will affect their rest, and it will also make the guppy in a state of fear and alert for a long time, which will affect their growth and development. Therefore, the best way to raise guppies is to use relatively static water flow. If you want to increase oxygen, you can turn down the oxygen switch to avoid them being frightened.
