There are many aquatic plants raised in the open-air fish pond, such as snapdragon, water hyacinth, duckweed and so on. Water hyacinth is a common choice, which is also called water hyacinth. It has strong adaptability, not only looks beautiful, but also has the ability to purify water quality. However, it is precisely because it grows easily that it is likely to over-breed, thus seizing the water surface and even causing fish to suffocate, so it is not suitable for large-scale planting.

1. Increase ornamental value: The first advantage of raising aquatic plants is to increase ornamental value. If there are only fish in the fish pond, it will look monotonous, but with aquatic plants as ornaments, it feels more like a natural landscape. In addition, some aquatic plants belong to emergent plants, so they will bloom and bloom beautifully.

2. Purify water quality: Aquatic plants can purify water quality. Because it lives in water, it can release oxygen through photosynthesis, improve the overall dissolved oxygen, and absorb some harmful substances, so that the water quality can be proudly improved, and the fish raised can be good when the water is good.

3. Provide food: Some aquatic plants can also be used as food for fish. Don't worry that the fish will eat the aquatic plants clean. As long as it is not a particularly destructive fish, the two can reach a balance, which can not only make the fish fill their stomachs, but also avoid the overgrowth of aquatic plants and affect the health of the fish.
