A Hygrophila corymbosa either thrives or melts within the first month, and the difference is almost always down to three things you can control. The Hygrophila corymbosa Hygrophila corymbosa is a workhorse plant for a reason: it tolerates a wide range of conditions and still looks good doing it.

Planting
Plant Hygrophila corymbosa with the crown or rhizome clear of the substrate — burying it rots the base. In a 36-gallon tank, position it mid-ground or background depending on its height. Weaker setups do fine; pair it with our dropsy prevention guide for a layered look.
Light and CO₂
Run 9 hours of light a day on a timer to avoid algae swings. Hygrophila corymbosa grows under medium light and not required, though a small, steady dose of liquid fertiliser every 4 weeks pushes denser growth.
Propagation
Stem cuttings root in substrate readily.
Common issues
Yellowing lower leaves usually mean a nutrient gap, not too little light. Trim dying leaves at the base, keep nitrates around 10 to 20 ppm, and avoid moving the plant every week — our rummy nose tetra care: the canary of the tank guide explains why stability beats tinkering.
Why it suits beginners
The Hygrophila corymbosa tolerates the small mistakes new aquarists make: missed water changes, uneven light, the occasional algae bloom. Keep the crown above the substrate and do not move it every week.
