Hornwort or Ceratophyllum is a super easy to grow plant for your planted aquarium. Hornwort is sometimes called Guppy Grass. I am not sure why it is called Guppy Grass. The obvious answer is that it is great for breeding guppies and other small fishes. The small leaves on Hornwort are perfect for small fry to hide from predators. What else I like about Hornwart is how fast it grows. Aquarium plants that grow at this kind of rate make for great "filtering" type plants. They can grow and absorb excess nutrients in your planted tank. We have lots of this plant and other fast growing filter plants like Java Moss and Duckweed. Just let us know what you are looking to do.
