Hygrophila balsamica

Description

Hygrophila balsamica is native to India and Sri Lanka. It's poisonous to fish and invertebrates if its emergent shoots are planted directly in an aquarium, but it becomes non-toxic when submerged. Most nurseries cultivate this plant emersed, which explains why it's rare in the hobby. H. balsamica thrives in tanks with high light intensity and CO2 levels, producing bright green leaves. It requires abundant iron but is relatively undemanding if basic needs are met. Propagation is easy, as the plant produces many lateral shoots that can form roots and develop into new plants when separated from the main plant. Regular trimming is necessary to maintain its shape, as it grows rapidly. In aquarium layouts, H. balsamica can be used vertically or induced to form a dense bush by cutting away the tip. It's suitable for Dutch-style tanks and can serve as a "filler" plant to create contrast with dark green plants like Java fern. However, it requires ample space in the aquarium due to its potential to grow massive.
