Pearl Weed

Pearl Weed (Hemianthus micranthemoides) is a popular foreground stem plant known for its tiny, bright green leavesand fast-growing, bushy appearance. Native to South America, it is often used as a carpeting or midground plant in freshwater aquariums, creating dense, vibrant greenery that provides a natural look and excellent hiding spots for small fish and shrimp.

This plant is moderate in care and thrives in high-light aquariums with CO₂ supplementation, which encourages compact growth and a lush carpet effect.

Care Requirements

• Lighting: Moderate to High

• Temperature: 20–28 °C

• pH: 6.0–7.5

• Growth Rate: Fast

• Placement: Foreground to Midground

Growth & Maintenance

Pearl Weed grows quickly and responds well to trimming. Stems can be cut and replanted to create dense clusters or carpets. CO₂ injection and nutrient-rich water help maintain tight growth, while high light enhances the plant’s bright green coloration. In lower-light setups, the leaves may become slightly elongated and less compact.
