About This Plant

Florida Aquatic Nurseries grows Aponogeton natans along with many of the other Aponogetons used in the Aquarium plant trad. Aponogeton natans is an aquatic bulb plant native to India and Sri Lanka Aponogeton natans is an excellent aquarium plant as the central focal point in a planted aquarium displaying dark green leaves that have an undulating margin. Aponogeton natans are bulb plants and will sometimes go dormant to the bulb stage of the plant. Just be patient and new leaves will begin to sprout. Sometimes it is helpful to take the bulb out of the aquarium for a resting period and keep it stored in moist sand until leaves begin to sprout. Then plant the Aponogeton bulb back into the aquarium.

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

Place in the midground between foreground carpets and tall background stems. The structure adds visual depth and shelters small fish and shrimp. 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.
