Pearlweed (Hemianthus micranthemoides)
Pearlweed is a fine-leaved, bright green stem plant that resembles a miniature version of baby tears. It's highly adaptable and can be used as a foreground carpet, midground bush, or even a floating plant. Under high light and CO₂, it grows compact and dense, but will grow more loosely in low-tech tanks.
 
Growth Height: 2–6 inches (5–15 cm)
Tank Size: Any
Care Level: Moderate
Lighting: Medium to high
CO₂: Recommended for compact, carpet-like growth
Propagation: Trim and replant stems
Notes: Grows toward light—frequent trimming helps shape it; ideal for nano tanks, Dutch-style layouts, or soft carpeting in aquascapes
