Planting

Plant Cryptocoryne parva with the crown or rhizome clear of the substrate — burying it rots the base. In a 33-gallon tank, position it mid-ground or background depending on its height. Weaker setups do fine; pair it with our sand vs gravel: which substrate should you choose? guide for a layered look.

Light and CO₂

Run 8 hours of light a day on a timer to avoid algae swings. Cryptocoryne parva grows under medium light and optional, though a small, steady dose of liquid fertiliser every 3 weeks pushes denser growth.

Propagation

Divide small rosettes once established.

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 — a solid otocinclus care: the dainty algae cat explains why stability beats tinkering.
