About This Plant
Bacopa myriophylloides is one of the more unique aquatic Bacopa species. Fine leaves make it resemble a member of the Myriophyllu m genus, but yet it is a Bacopa . Bacopa myriophylloides prefers bright light and supplemental CO2. Use Bacopa myriophylloides to add a different texture to your planted aquarium.
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 — 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. 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 Bacopa myriophylloides
- 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.
