When planting aquatic plants in a koi fish tank, it is necessary to select plants that can not only purify the water quality but also provide shelter and a food source for the koi. Here are several types of aquatic plants that are most suitable for koi fish, and they are recommended as follows:
Calamus, Water Hyacinth, Water Celery
These aquatic plants can effectively absorb harmful substances in the water, such as ammonia nitrogen and nitrates. At the same time, they provide shelter and a food source for the koi, making them an ideal choice for maintaining clean water quality.
Lucky Bamboo, Creeping Wire Vine
Lucky bamboo and creeping wire vine are common choices for koi fish tanks. They are not only easy to maintain but also can provide a good living environment for the koi. However, it should be noted that since koi are relatively large in size and have a high demand for oxygen, it is not advisable to plant too many aquatic plants, so as not to consume too much oxygen.
Water Lily, Hornwort
Water lilies and hornwort are natural aquatic plants that can filter microorganisms in the water and purify the water quality. Water lilies are especially suitable for use in urban water body purification, while hornwort can serve as feed for koi.
Moss Aquatic Plants
Moss aquatic plants have strong ornamental value and are suitable for co - raising with small fish. However, it should be noted that moss aquatic plants are not suitable for co - raising with large ornamental fish such as koi, because they are easily eaten by the koi.
Duckweed
Duckweed is a natural aquatic plant that can effectively absorb nutrients in the water and reduce the concentration of ammonia nitrogen and nitrates. You can put duckweed seeds or seedlings in the fish tank, but it is necessary to clean them regularly to avoid affecting the water quality.
Conclusion: When planting aquatic plants in a koi fish tank, you should choose plants that can both purify the water quality and provide shelter and a food source for the koi, such as calamus, water hyacinth, lucky bamboo, etc. At the same time, it is necessary to pay attention to controlling the number of aquatic plants to avoid consuming too much oxygen or breeding bacteria.
