Ceratopteris Cornuta (Ceratopteris cornuta)

Ceratopteris cornuta, commonly known as Water Sprite, is a fast-growing and highly versatile aquatic fern that is popular among aquascapers and beginner fishkeepers alike. Its delicate, bright green, lace-like leaves create a soft, natural appearance while providing excellent cover for fish, shrimp, and fry. Whether planted in the substrate or left floating on the surface, this adaptable plant adds texture, movement, and a vibrant splash of green to any freshwater aquarium.

Thanks to its rapid growth, Ceratopteris cornuta is excellent at absorbing excess nutrients from the water, helping to reduce algae growth and improve overall water quality. Its low-maintenance nature makes it one of the best plants for newly established and community aquariums.

Ceratopteris cornuta grows well in nutrient-rich aquariums with stable water conditions. If planted, avoid burying the crown too deeply, as this can cause it to rot. Many aquarists choose to float the plant, allowing its long roots to hang beneath the surface where they provide outstanding shelter for fish fry and shrimp.

Regular trimming encourages bushier growth and prevents the plant from shading slower-growing species beneath it.

Important Notes

Ceratopteris cornuta is one of the fastest-growing aquarium plants available and may require regular pruning to prevent it from dominating smaller aquariums. Floating specimens can spread quickly across the surface, so occasional thinning may be necessary to allow light to reach plants below.

As a rapid nutrient consumer, this plant is highly effective at helping maintain water quality and limiting algae growth, making it an excellent choice for both new and established aquariums.

Under favourable conditions, mature plants often produce small plantlets on the edges of their leaves. These can simply be detached and replanted elsewhere, making propagation quick and easy.

Ceratopteris cornuta is a superb choice for UK aquarists looking for a beautiful, hardy, and easy-to-grow aquarium plant. Its elegant fern-like foliage, rapid growth, and ability to provide shelter while improving water quality make it an excellent addition to community tanks, breeding aquariums, and natural aquascapes of all sizes.
