About This Plant

Previously known as Echinodorus angustifolia 'Vesuvius'. Like all "chain swords", this one has been moved to the genus, Helanthium It has also been determined that H. angustifolia is a synonym of H. bolivianum . Helanthium bolivianum is very interesting aquarium plant and is fast growing. It spreads easily by runners. For the aquarium hobbyist who has been looking for new and different varieties of sword plant, this will be an outstanding addition. Lighting conditions from low to high will work with the medium range being optimal in the aquarium. 'Vesuvius' derives its name from the curl of the leaves similarity to wisps of smoke off the top of Mount Vesuvius. H. bolivianum 'Vesuvius' was developed by Eu Kwee Hwang of Oriental Aquarium, by selecting from normal plants of Helanthium bolivianum "Angustifolius". For more information, click here .

About the Echinodorus Genus

Family — Alismataceae

Echinodorus ("Amazon swords") are large rosette plants from South American river basins, used as background or specimen plants in larger aquariums. They are heavy root feeders, so a nutrient-rich substrate or root tabs make a noticeable difference in leaf size and color.

Quick-Reference Details

Common name: Helanthium bolivianum 'Vesuvius'
Scientific name: Echinodorus Altlandsberg
Family: Alismataceae
Native to: Cultivar
Difficulty: Advanced
Requirements: Undemanding, but does best with regular fertilization and supplemental CO2
Lighting: Low - High
Growth rate: Medium
Growth form: Rosette
Placement: Mid-ground (or back of a smaller tank)
True aquatic: Yes
Available as: Potted or bare root

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

Plan for at least 20 gallons. Rosette plants spread a foot or wider once established and need vertical room.

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.

Pro Tips for Growing Helanthium bolivianum 'Vesuvius'

1Add root tabs every 3-4 months under the rosette — sword plants are heavy substrate feeders.
2Trim outer leaves at the base, not partway up the leaf — partial cuts brown back and look ragged.
3Daughter plantlets that grow on the flower stalks can be cut off and replanted as new specimens.

Common Care Issues

Algae outbreaks

High-light plants without matched CO2 and nutrient dosing reliably trigger algae blooms. If you can't run pressurized CO2, choose a lower-light alternative or accept some algae management.

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.
