Basic care information: Bacopa 'Japan' is a compact aquarium plant with small, bright green leaves and stems that can spread horizontally under suitable conditions. It is useful for creating low, bushy growth around rocks and driftwood. Provide moderate to high lighting, a nutrient-rich substrate, and regular liquid fertilization. Supplemental CO₂ encourages denser growth but may not be essential in lower-tech aquariums. Maintain water around 20–28°C with a pH of approximately 6.0–7.5. Trim the stems regularly to encourage branching, and replant healthy cuttings to propagate the plant. Under lower lighting, it may grow more vertically rather than creeping along the substrate.
