About This Plant
Cabomba caroliniana is one of the more common aquatic plants in the aquarium trade. Cabomba caroliniana is a native plant to the United States and makes a great background for the planted aquarium. Cabomba caroliniana also provides a great hiding place for small fish in the aquarium. Long stems with finely pinnate leaves give Cabomba caroliniana its unique texture. Green Cabomba as it is more commonly known should be trimmed often to maintain its height. The trimmings from the Green Cabomba can then be replanted to grow new plants.
About the Cabomba Genus
Family — Cabombaceae
Cabomba are fan-leaved stem plants with finely divided foliage. They need bright light to keep lower leaves; in dim tanks they get leggy and bald at the base.

Difficulty — Advanced
Performs best with strong lighting, CO2 supplementation, and stable water parameters. Not recommended as a first plant.
CO2 & Fertilization
CO2 supplementation is recommended for best growth and color. Liquid carbon (Easy Carbon, Excel) is a workable substitute, though pressurized CO2 produces the strongest results.
Tank Size & Setup
Best in tanks 20 gallons or larger so background stems have room to grow up and be trimmed without overtaking the foreground.
Aquascaping & Placement
Place in the midground between foreground carpets and tall background stems. The structure adds visual depth and shelters small fish and shrimp. Trim and replant the tops every 3-4 weeks. The new growth tips hold the best color and form, while lower stems eventually need replacing.
Tank-Mate Compatibility
Compatible with the full range of community-tank species — tetras, rasboras, livebearers, corydoras, and most other peaceful freshwater fish do not damage the foliage.
Pro Tips for Growing Cabomba caroliniana
- 1Cabomba needs strong light — in dim tanks it gets leggy and bald at the base.
- 2Replant the tops every few weeks rather than trimming; lower stems brown out.
Common Care Issues
Outgrowing the tank
Plan to trim every 1-2 weeks. Skipping trims lets the plant shade out neighbors and trap detritus that fouls water quality.
Slow initial growth
Most aquarium plants pause for 2-4 weeks after planting while they convert from their nursery-grown emersed form to fully submerged growth. New leaves that emerge underwater will look thinner and slightly different — this is the plant adapting, not a problem.
