Although guppy is not picky about food, there are not many foods that newborn guppy can eat, and their digestive ability is weak, so it is necessary to choose some nutritious and digestible foods to feed them. The food suitable for small guppies is shrimp eggs, broken red worms, Daphnia, paramecium, backwater, cooked egg yolk and so on.

When feeding small guppies, breeders should follow the principle of eating less and eating more. This can not only ensure their adequate nutrition, but also avoid indigestion. The breeder can feed them 2-3 times a day, and the amount of each feed can be eaten within 5 minutes.

Small guppies are sensitive to the fluctuation of water quality, so it is best for breeders not to change water within one week before their birth. After waiting for a week, even if you can change water, the amount of water should not be too large, and it can be controlled at a quarter of the total amount of water. Small fry are also sensitive to water flow, so it is best for breeders to inject new water slowly when changing water to avoid water impact on fish. If conditions permit, it is best to choose trickle to change water, which can reduce the discomfort of small fry.

The pollution of guppy fish to water quality is not serious. Under normal feeding conditions, the breeder can change the water for them once every 5-7 days. When the water temperature in the fish tank is on the high side, the water can be changed once every 3-5 days. If there is a circulating filtration system, the frequency of water change can be extended.
