Ceratophyllum demersum is one of the most popular aquarium plants in the trade. Hornwort, or Coontail as it is more commonly referred to, is able to 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 fine 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 in.

    Normally better quality

    Normally I get better quality when I get plants from this website. There were a few snails I had to get rid of and still getting rid of and there are dark moss or feces like deposits on the stem and in the leaves. The plant looks healthy except for these two issues

    I received this plant in great condition. They were approximately 8 inches long. Within one week they have reached the top and covering the top of the tank. Loving this plant!

    Plants came in nice and green generous portions. Very little die off in my tanks. They have even started to grow already!
