Its advantages are strong vitality, fast immobilization, and can be preserved for several days without dying, but its disadvantage is that it is relatively small. If it is used as feed, it is difficult for fish to prey on it because it swims fast. Therefore, before feeding with sword water fleas, it is usually scalded with boiling water.

And plant feed must be cleaned before feeding, and check for pests or eggs. It is best to soak it in low concentration potassium permanganate before feeding.

Of course, with synthetic feed, it is much more convenient to raise crucian carp at home. Moreover, the nutritional components of synthetic feed are relatively complete, which is more in line with the needs of crucian carp's growth and development.
