Cryptocoryne parva: the foreground crypt

Cryptocoryne parva is the smallest of the genus, with lanceolate leaves of barely 5 to 10 cm that form a low, very natural-looking carpet. It is the only crypt that works well in the foreground. Its weak point is slowness: it takes months to cover an area, and that slowness leaves it vulnerable to algae getting there first if the tank is not balanced.
