the newborn fry? The newborn fry can be filtered with water goblins. Water goblin, also known as sponge filter, is a kind of filtering equipment that needs to be connected to oxygen pump and air hose. Its power is not high, but it uses less water to raise small fish fry, so it can maintain water quality and will not make the water deteriorate rapidly. And because its power is relatively low, it will not affect the movement of the fry, nor will it suck it into the filtration equipment.
the fry 1. Feeding: The newly hatched fry does not need to be fed until the next day. At this time, the fry can not eat fish food, need to feed some special food, such as cooked egg yolk, migration water, soybean milk, etc., of which migration water is the best food, cooked egg yolk and soybean milk will be bad water risk.
2. Change the water: Fish farming needs to change the water, but the adaptability of the fry to the water quality is poor, so it can not be changed too early. Usually, the water should be changed for the first time a week after it hatches, and it should not be changed too much. It can be changed by a quarter or a fifth. Be careful when changing the water, so as not to frighten the fish.
3. Temperature control: Small fish fry often have higher requirements for temperature. Usually, the water temperature is about 1-2 ℃ higher than that of adult fish. Such higher temperature can not only promote metabolism, which is conducive to its growth, but also prevent a variety of diseases, which is of great help to the health of fish.
