Scientific Name: Ceratopteris thalictroides

Common Name: Water Sprite, Indian Fern, Water Hornfern

Water Sprite (Ceratopteris thalictroides) is a highly adaptable aquatic fern native to tropical and subtropical regions across Asia, Africa, and the Americas. Its finely divided, lace-like fronds contrast with broader-leaved plants, helping replicate the natural textures and sizes of aquatic plants. In blackwater and botanical method aquariums, this species thrives either rooted or free-floating, absorbing excess nutrients and providing refuge for fry and shrimp.

Often described as one of the most forgiving aquatic plants, Water Sprite grows rapidly in a variety of conditions, from shaded low-tech systems to well-lit, CO₂-enriched aquascapes. It plays a valuable ecological role by stabilizing nutrient levels, helping to reduce algae growth, and supporting the microbial community that develops among its fronds.

Many aquarists allow older, slightly browned leaves to remain intact, as they frequently produce small plantlets—a natural propagation process similar to Java Fern. Each mature frond may host multiple young plants that can be separated and replanted to establish new colonies.

Caring for Water Sprite in Blackwater Aquariums

Sold As: Both potted and bare root plants

Care Level: Easy; excellent for beginners

Lighting Requirement: Low–medium; higher light encourages faster vertical growth

CO₂: Not needed

Growth Rate: Fast; capable of filling the midground and surface zone

Tank Placement: Midground–background, or as a floating plant

Native Habitat: Asia and tropics worldwide; found in swampy forests, marshes, and slow-flowing rivers

Tint Tolerance: High; remains vigorous in tinted and humic-rich water conditions

Note: Some leaves may arrive with light browning—these are often fertile fronds carrying developing baby plants. We recommend leaving them attached until the plantlets are large enough to separate and replant.
