About This Plant

Cyperus helferi is an excellent aquarium plant to add a grass like look in the aquarium. The long leaves of Cyperus helferi wave in the current and are very pleasing to the eye. Plant Cyperus helferi in multiple pieces to help create a full backdrop or plant near moving water in the aquarium to see it move in the current. Cyperus species have been popular in the water garden industry for many years, but Cyperus helferi is the first species to be used totally submerged in an aquarium. Cyperus helferi can grow very large, but it is also not difficult keep tamed down, by removing the older, outer leaves. If purchased in a tissue culture package, the plants are fairly small, and can be used successfully in a smaller tank for quite some time.

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. Plant the root crown just at the substrate surface. Burying the crown causes the plant to push itself back up over a few days.

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.

Common Care Issues

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.
