Description
Plant Profile
Cabomba aquatica, commonly known as Yellow Fanwort or Giant Cabomba, is renowned for its captivating, delicate aesthetic that instantly softens an aquascape. Its standout feature is its intricate foliage, where each stem produces opposite pairs of fine, finely divided, fan-shaped leaves that spread out in precise, circular whorls along slender upright stalks. In healthy conditions, the delicate needle-like segments radiate outward in bright lime green to subtle yellow-green tones, creating a cloud-like, feathery texture underwater. When planted in tight clusters in the midground or background, these lush plumes merge into a thick, pillow-soft wall of greenery that sways elegantly with water circulation. Compared to some of its finicky reddish relatives, Cabomba aquatica offers a far more forgiving experience while delivering that prized, highly detailed foliage style.
Key Features & Notes
Feathery, fan-shaped leaves arranged in circular whorls create a soft, cloud-like visual texture.
Vibrant lime-to-yellow-green foliage adds bright contrast and fine detail to background groupings.
Hardier and more forgiving than red Cabomba species, making it an accessible choice for fine-leaved stem lovers.
Care & Planting Instructions
Prep the plant by removing it from the lead wrap or pot and clearing all rockwool from the roots.
Plant individual stems into aquarium soil using fine-tipped tweezers, spacing them slightly apart to ensure light reaches the lower fan blades.
Provide moderate-to-high light to keep the fan whorls compact and prevent the lower stem portions from shedding leaves.
Propagate by trimming the upper stem tops with sharp aquascaping scissors and replanting them directly into the substrate.
Maintain clean water conditions and avoid sudden parameter fluctuations to prevent delicate leaf shedding.
Final density and leaf color depend on lighting and nutrient availability; please note that photos are a representation, and individual plants may vary.

Frequently Asked Questions
1. Why are the lower fan leaves on my Cabomba aquatica turning yellow or falling off?
This is typically caused by insufficient light reaching the lower stem nodes. Because the upper fan whorls create dense shade as they reach the surface, space stems slightly apart during planting and trim top growth regularly to allow light penetration to the base.
2. How do I trim fine-leaved Cabomba stems without damaging the fan structure?
Use extremely sharp aquascaping scissors to make a clean snip directly above a leaf whorl node. The parent stem will branch out with multiple new shoots from that point, while the trimmed top can be replanted to build a denser bush.
3. Will Cabomba aquatica lose its fan shape in a low-tech setup without CO2?
No, it will retain its signature fan-like leaf structure without pressurized CO2, though providing adequate light intensity and liquid nutrients is essential to keep the leaf needles full, compact, and brightly colored.
