First, read the English article below.

You can feed your guppies all kinds of food, both dry and wet, and both live and frozen. You can buy pre-made flake food for guppies that will provide them with a balanced diet, but make sure you avoid feeding them solely a high-protein food. You want to balance protein with vegetable-based food.  Brine shrimp, earthworm flakes, dried bloodworm, white worms, and mosquito larvae are all great options for feeding your guppies. Flake food with fish meal as a primary ingredient is a great choice. Read the labels before buying your guppy food. Rather than feeding your guppies a large amount all at once, spread their feedings out throughout the day. Try to vary what you give them each feeding. For example, you might give them live brine shrimp during one feeding, and then flake food at the next feeding. Be careful not to overfeed your guppies. They should be able to consume the food you give them within two minutes. The tank water is a good indicator of how well the fish are thriving on their diet. If the water goes cloudy, or if there seems to be a problem with algae in your tank, you might be having some issues with your feeding. If your tank goes cloudy, lighten up your feeding by about 20% for a few days and see if that helps the fish readjust and the water to balance itself out again. If this happens it might be due to a peak of toxic substances (ammonia and nitrite) because of skipping the cycling period...
