About This Plant

Florida Aquatic Nurseries grows Aponogeton rigidifolius . Aponogeton rigidifolius is native to the island nation of Sri Lanka Aponogeton rigidifolius is an excellent, though demanding aquarium plant as the focal point in a planted aquarium. It has long dark green leaves that have undulated margins. Aponogeton rigidifolius is not a bulb plant like most Aponogeton sp. Instead, this species has long, thin rhizomes, and requires no rest period. Over time, in excellent conditions, the plant will spread into an impressive stand.

About the Aponogeton Genus

Family — Aponogetonaceae

Aponogeton are bulb plants that produce long, flowing leaves and benefit from a seasonal rest period — many varieties will die back, then resprout from the bulb after a few months of dormancy. They are dramatic background plants for medium-light tanks.

Difficulty — Intermediate

Grows reliably in moderate-tech tanks. Benefits from steady fertilization and adequate light, but does not require CO2 to survive.

CO2 & Fertilization

CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.

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

Plant at the back of the tank as a vertical accent or full background curtain. Group stems in clusters of 5-10 for a fuller display. The rhizome is the green horizontal stem. Attach it to driftwood, lava rock, or stone with cotton thread or super-glue gel — burying the rhizome causes rot.

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

Rhizome rot

The rhizome (the thick horizontal stem) must stay above the substrate. Buried rhizomes turn black and mushy within a few weeks. Tie the plant to hardscape or wedge it between rocks instead.

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.
