About This Plant
Bacopa monnieri is a very undemanding aquatic plant and makes a great choice for beginners. Moneywort, as it is known by its common name has small, round, green leaves that help to add a different texture in the aquarium. Use Bacopa monnieri as a background plant in a smaller tank or keep some stems trimmed back in the midground area of the larger planted aquarium. It does equally well in warm or cool water aquariums. Remember when you trim the stem plants in your aquarium, the cuttings can be replanted to make additional clusters. Bacopa monnieri is also a native aquatic plant to the United States that can be used in settings ranging from water garden borders to fully submerged aquariums.
About the Bacopa Genus
Family — Scrophulariaceae
Bacopa is a versatile genus of stem plants that adapts to low or high light and grows both submerged and emersed. Pinching the growing tip encourages side shoots and a bushier form.

Difficulty — Advanced
Performs best with strong lighting, CO2 supplementation, and stable water parameters. Not recommended as a first plant.
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. Trim and replant the tops every 3-4 weeks. The new growth tips hold the best color and form, while lower stems eventually need replacing.
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 Moneywort
- 1Pinch the growing tip to encourage side branching and a bushier shape.
- 2Bacopa is highly adaptable — it grows submerged, emersed, and in paludariums.
Common Care Issues
Outgrowing the tank
Plan to trim every 1-2 weeks. Skipping trims lets the plant shade out neighbors and trap detritus that fouls water quality.
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.
