The central highlands of Sri Lanka are home to this green cryptocoryne. A small stature of around 5 - 10 cm makes it the smallest species that is cultivated for aquatics purposes. It grows in dense colonies along the banks of fast-flowing rivers. Cryptocoryne parva grows very slowly and is a slightly more demanding plant. Stronger lighting and CO2 supplementation are essential. This small Cryptocoryne is highly recommended for Nano Cubes. Even the smallest 10 L Cube provides enough space for this little nursling.
