Live Aquarium Plant Bacopa Monnieri Moneywort for Easy Midground or Background Planting in Low-Tech Tanks

If your planted aquarium needs an easy, cheerful layer of greenery, Bacopa monnieri brings upright stems and rounded light green leaves to the midground or background.

Also known as Moneywort or Water Hyssop, this hardy stem plant suits beginner care and low-tech setups. Its clean vertical growth adds structure without requiring CO2, while moderate-to-high lighting supports steady development.

Key Features

• Hardy stems and thick, fleshy foliage adapt readily to low-tech aquariums, making this plant approachable for newer planted-tank keepers.
• The upright growth habit creates clean vertical lines, while light green leaves add a fresh contrast around hardscape and neighboring plants.
• Easy care and no mandatory CO2 system make Moneywort a practical choice for a simpler aquarium routine; CO2 may be used to encourage faster growth.
• Planting individual stems 1 to 2 inches into the substrate gives them a clean anchor, while spacing allows light to reach the lower foliage and reduces stem rot.
• Moderate-to-high lighting supports steady growth and keeps the lower portion from being shaded, which matters because insufficient light can lead to lower-leaf loss or basal rot.
• When stems reach the water surface, trimming the tops encourages lateral side branches; the cut tops can be replanted for propagation.
