About This Plant

Florida Aquatic Nurseries grows Aponogeton longiplumulosus as well as many of the other Aponogeton sp. used in the Aquarium plant trade. Aponogeton longiplumulosus is an aquatic plant native to the island nation of Madagascar. Aponogeton longiplumulosus is an excellent aquarium plant as the central focal point in a planted aquarium displaying long dark green leaves that have undulating margins. Aponogeton longiplumulosus are bulb plants and are likely to go dormant intermittently. Unlike other Aponogeton sp., it is usually unnecessary to remove the bulb from the aquarium during its rest period. Just be patient and new leaves will begin to sprout.

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. Set the bulb on top of the substrate, not buried, until roots take hold. Expect a dormant period after flowering.

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.
