Peacock fry do not need oxygen under normal feeding, because their demand for oxygen is not very high, and peacock fry are relatively small and consume less oxygen. As long as feeding and breeding can ensure regular and quantitative water change, the oxygen in water is enough for them to absorb. As long as the breeding density is not particularly high, it is ok not to give them oxygen. In addition, guppies like to grow in still water, and oxygenation may lead to an increase in water flow in the fish tank. In addition, peacock fry have poor adaptability to the environment, and too much water flow may lead to more discomfort.

1. Food types: Peacock fry have weak digestion ability and can eat few kinds of food. Breeders can choose to feed some highly nutritious and digestible foods. For example, shrimp eggs, red worms, Tenebrio molitor, lean meat, etc., and some fruits and vegetables, etc., to ensure their balanced nutrition.

2. Feeding amount: The appetite of peacock fry is not large, so it is best for breeders to feed them in small quantities for many times. This can not only avoid indigestion, but also ensure adequate nutrition. Usually, it can be fed 1-2 times a day, and the amount of each feeding can be finished within 3-5 minutes. If they don't eat well, breeders need to reduce the frequency and amount of feeding.
