01
Overview
Cabomba has furnished fish-store display tanks for a century, its paired fans opening like green fireworks along each stem. It genuinely prefers soft, slightly acidic water and steady light; in hard alkaline tanks it thins into a shedding skeleton, which explains its mixed reputation.
Water note: Acidic to near-neutral water is preferred; ecological sources show reduced growth in alkaline conditions.
02
Aquascaping use
A backdrop of it suits classic community layouts and breeding tanks, where egg-scattering fish use the fans as cover. Keep it out of strong surface turbulence, which batters the foliage.
03
Planting
Plant cuttings gently; the brittle stems snap under rough tweezers. Weight or hold them until rooted, as fresh stems float free easily.
Flexible
04
Light & CO₂
Medium light minimum, and it repays CO₂ with fuller fans. Shade or hard water start the leaf-shedding spiral quickly.
05
Substrate & fertilization
Column feeding suits its rootless-leaning habit. Keep iron and potassium present or fans pale and shatter.
Feeding behavior: Water-column feeder. Nutrient demand: moderate.
06
Growth, trimming & propagation
Top and replant healthy crowns; shed foliage should be netted before it fouls the tank. Handle trimmings responsibly given its invasive record.

Common problems
This fragment-spreading species is legally restricted in many jurisdictions. Verify local law, never release it, and securely dispose of every cutting and loose fragment.
- !Sheds needles in hard or turbulent water
- !Brittle stems break during handling
- !Regulated as invasive in many places
