A water plant that very effectively helps to clear pond water and add oxygen for your fish, Hornwort makes a great addition to the garden pond, water feature, or aquarium. Your happy fish will thank you for adding this super easy to grow aquatic plant.
Another wonderful aquatic plant for the water feature in in your garden is the Hornwort or Ceratophyllum submersum. This plant these fish are feeding on is completely submersed under the water. It grows in shallow water and the reason we grow it in our water features is that it provides great cover for small fish, they spawn, lay eggs inside of its cover, and also it oxygenates the water. That's an important aspect of when you have fish in your pool or water feature.
This plant is an excellent one to include in your water garden for the simple reason that it emits allelopathogens that suppress algae growth. So if you want clear water without chemicals this is the plant for you. It is one of the oldest plants that goes way back into the fossil record back as far as the cretaceous. It is a very primitive plant it's one of the bryophytes which means it's non-flowering. It reproduces by spores. It is a really lovely plant providing not only cover for the fish to spawn in but also it catches the movement of the water in a wonderful way. For the longest time this plant was considered part of the same family as the water lily nymphae but there are obvious differences morphologically between this plant and the water lily.
This plant can be easily propagated by breaking off a piece and placing it in your pond. You can free float it like i just did or you can pin it down or weight it down and it will keep it in one place. Hornwort is a very practical oxygenator for the water garden or the water feature.
Hornwort Ceratophylum submersum is related to Ceratophylum demersum but is softer with finer foliage.
A great garden plant to grow in your aquarium.
