Bacopa madagascariensis

Lush, compact, and charmingly textured — Bacopa madagascariensis is a lesser-known but highly rewarding stem plant from Madagascar, prized for its small, rounded leaves and dense, bushy growth habit. A versatile midground and background plant, it brings a soft, layered texture to planted aquariums and is easy to propagate by cuttings, making it a practical and attractive choice for aquascapers of all levels.

Overview

Appearance

Bacopa madagascariensis produces small, rounded to slightly oval leaves arranged in opposite pairs along each stem, giving it a neat, symmetrical appearance. The foliage is a fresh mid-green that remains compact and tidy under good lighting. Planted in groups, it creates a dense, lush mass of texture that works beautifully as a midground filler or soft background element in nature and Dutch-style aquascapes.

Water Parameters & Care

• Temperature: 64 – 78°F (18 – 25°C)
• pH: 6.5 – 7.2
• General Hardness (GH): 3 – 10 dGH
• Carbonate Hardness (KH): 1 – 2 dKH
• TDS: 100 – 300 ppm
• Lighting: Moderate to high — promotes compact, bushy growth
• CO₂: Not required, but beneficial for faster growth
• Fertiliser: Benefits from regular liquid fertiliser and a nutrient-rich substrate

Propagation & Planting

Bacopa madagascariensis is easy to propagate — simply take a healthy side shoot or stem cutting and plant it directly into the substrate. New roots will develop quickly. Plant stems 2 – 3 cm apart and trim regularly to encourage dense, bushy growth and prevent legginess. Replant trimmings to fill in gaps and create a fuller, more natural appearance.

Compatibility

Compatible with all freshwater fish and invertebrates. Safe for shrimp tanks. Avoid housing with herbivorous fish that may graze on the soft stems. Pairs well with contrasting textures such as fine-leaved stem plants, mosses, and broad-leaved midground plants like Anubias or Bucephalandra.

Bacopa madagascariensis is an easy-going, attractive stem plant that rewards regular trimming with lush, compact growth. A reliable and underrated choice for any planted aquarium.
