Guppies don’t need oxygen. Whether or not oxygen is needed to raise guppies mainly depends on the feeding density. Normal feeding density does not require oxygen. If the feeding density is relatively high, oxygen is required. Guppies themselves are not fish with high oxygen consumption, and they are relatively small, so they do not need too much oxygen, but they need to install filtering equipment.

Tip:

When raising guppies, the fish tank should be placed in a ventilated position. When the weather is hot and muggy, you can reduce the amount of feeding or stop feeding, and do not change the water to prevent the guppies from suffocating due to lack of oxygen. In addition, when the weather is cold, you need to install a heating rod in the fish tank to maintain the water temperature.
