    Description

    Hornwort (Ceratophyllum demersum) is one of the most widely kept aquarium plants in the world, producing long, branching stems of feathery, dark-green whorled needles. It is a rootless plant — absorbing all its nutrients directly from the water column — which means it can be floated freely at the surface or gently anchored in the substrate to create a background effect.

    It is extremely easy to grow, tolerating a wide range of water conditions, temperatures, and light levels. Its rapid growth makes it an excellent nutrient absorber, helping to suppress algae in both new and established aquariums. It also releases natural growth-inhibiting compounds that can help keep certain types of algae in check.

    Supplied as established cuttings, Hornwort is particularly valuable for aquariums housing fry or shrimp, as its dense, feathery growth provides natural shelter and grazing surfaces. It is equally useful in pond set-ups and coldwater aquariums where few other plant species will thrive.

    Customers praised this fast-growing aquatic plant for arriving healthy and in excellent condition. Many noted it "grows like wildfire" and provides great oxygenation. Fish and shrimp love swimming through its delicate, feathery foliage. Some concerns: difficult to root, can be eaten by goldfish/turtles, and occasional delivery issues. A few felt quantity was small for price.

    Delicate and different

    What a lovely plant, with its delicate feathery appearance! It has settled in well a week after delivery, and was today introduced to the fishes in the other tank! I haven't tried Hornwort before, but, like Elodea, it doesn't take up much room without a plant pot, so if it does well I may choose this again.

    Unfortunately the plant took over a week to arrive which was down to delays with Royal Mail. I was expecting the plant to be pretty damaged but it was completely unsalvageable. It was packed in a sandwich bag with a bit of water and was broken up into tiny bits which were basically impossible to pin down in my tank. On top of this most of it had gone brown and died off. I would recommend if you’re thinking of buying to be mindful that Aqua Essentials don’t offer refunds or replacements if there are problems with Royal Mail delivery as i spent about £7 + £5 shipping for a plant which is completely unusable. I also had no reply to the emails I sent their customer service address.

    Love the plants, arrived very healthy. A bit tricky to keep it in the ground as they grow no roots, but I managed with some weights and it's swaying in the current.

    Oh my goodness how this one spreads and grows . The fish play in it all day. I love it. It looks so pretty in the tank. Only problem is the snails also love it. Was quite disappointed by the snails as I'm sure I read no snails no pests. Not sure which plant the snails came with but they definitely came with the plants as was a complete new set up from scratch. But the plants have more than made up for the snails. Thank you so much for such beautiful plants.
