Ceratophyllum demersum is one of the most popular aquarium plants in the trade. Hornwort, or Coontail as it is more commonly referred to, can tolerate a wide range of aquatic conditions, which is the reason for its popularity. Ceratophyllum demersum is also very common in the water garden industry, where it is used as an oxygenating plant for small water features and ponds. Hornwort is okay with just being floated in a body of open water and can be broken into pieces to establish new plants. Ceratophyllum demersum is native to the United States and makes an excellent habitat for fish to lay eggs on or hide among.

Planting Instructions

Stem plants are usually cuttings of plants that generally don't come with roots. This is how stem plants are sold in the aquatic plant industry, although at times, my stem plants may come with roots because I have been growing them out. All stem plants come with a plant weight that holds the plant in place and is safe for your tank. 

To plant, just let the weight lay on your substrate, and the stems will grow roots throughout your substrate. You can also plant the tips, about 1/4" in your substrate if you prefer.

The ease and supremacy of this plant is not hyperbole. Give it some light, maybe a few nutrients, and suddenly it's grown across the top of your tank. My shrimp love it, my ember tetras love it, everybody loves it except maybe the monte carlo I am trying to grow under it; it'll grow thick enough to block light! But if you're after an easy, robust, GREEN plant, you can't go wrong with this one, and it arrived with generous, healthy portions to boot.

Had issue but solved quickly
I bought this hornwort with other 7 plants. All others were very good, but horwort broke down into small debris when I received them. I told them this situation and they gave the credit back to me immediately. Although I got some issue, the quick response was amazing. I feel good to the customer service. Definitely I will buy plants here again.

Happy Customer
The Hornwort I ordered arrived in healthy condition, packaged and insulated securely. I rinsed it off and followed the acclimation instructions included, before planting directly into a take with no fertilizer or CO2. The plant weight they included is a necessity for Hornwort in a tank with high flow like mine. The plant cuttings have flourished and doubled in size and density in the two months I've had them. In other words, I couldn't be happier with my order!
