Originating from the hіghlаndѕ оf central Sri Lаnkа near thе сіtу оf Kаndy, Cryptocoryne parva is the smallest of the water trumpet species. It grows quite slowly, even under ideal conditions. Providing a nutrient-rich substrate and CO2 improves growth, although not significantly. Due to its small size, the plant is ideal for nano tanks or foreground placement in larger tanks.
