Hygrophila guianensis

Hygrophila guianensis is a South American species of Hygrophila from the Guiana Shield region, bearing elongated, lance-shaped leaves with attractive fine serrations along the leaf margins that distinguish it from the smooth-edged Asian Hygrophila species dominating the hobby. It is a hardy, adaptable plant that grows at a moderate to fast pace under a wide range of water conditions, making it accessible to aquarists at all skill levels. In the aquascape its serrated leaf edges add subtle textural detail to background plantings and provide a point of botanical interest for hobbyists seeking to diversify beyond the standard Asian Hygrophila collection.

Light: Low to medium (20–40 PAR); adapts well to variable lighting conditions. CO2: Not required; tolerates low-tech setups comfortably. Fertilisation: Moderate regular fertilisation; tolerates a broad nutrient range. Placement: Background in medium to large tanks; excellent community tank background plant. Propagation: Cut 10–15 cm stems; roots very easily with no special requirements.
