or not depends on the density of feeding. If the density of feeding is not large, there is no need for oxygen. Because guppies themselves are not high oxygen consumption fish, especially small guppies, the demand for oxygen will be less, so breeders can not give them oxygen, just need to change water frequently.
If the breeding density is high, oxygen is needed, because if the density is high, the dissolved oxygen in the water will be reduced, and hypoxia can easily lead to discomfort or death of guppies. If you don't have an oxygen pump, you can change the water 2-3 times a week to ensure adequate oxygen. The circulating filtration system can also be opened, and a small amount of oxygen can be added.
? Guppy is ovoviviparous, so it is a small fry at birth. Newborn guppy fry do not need to be fed because they have enough lecithin from their mothers to absorb it for 2-3 days. Three days after birth, they need to be fed, and they can feed some easy-to-digest foods such as shrimp, cooked egg yolk and so on. At this time, the amount of feeding does not need to be too much, but it needs to be fed every 2-3 hours. After a week or so, they can eat some red worms, tubificidae and synthetic feed, which can be fed 2-3 times a day.
