Ciliated Cryptocoryne

Geographical Origin and Habitat: Widely distributed in South and Southeast Asia, from India through Indonesia to Papua New Guinea. Found in brackish tidal zones, mangrove swamps, and estuaries.

Taxonomy & Genetics: Belonging to the Araceae family and Cryptocoryne genus. Named ciliata because of the fringed or ciliated margin of the spathe (flower).

Physical Structure: One of the largest species in the genus. It grows in a rosette form with upright, lanceolate leaves on thick petioles, developing a very large root system.

Color & Texture: Leaves are bright light green to olive green, smooth with a prominent and thick central vein.

Lighting & CO2: Medium light demand. Proper lighting helps keep the plant compact. CO2 injection is beneficial but not strictly necessary for survival.

Nutrition & Substrate: Requires a deep, nutrient-rich substrate since it is a heavy root feeder. Root tabs containing iron and micronutrients are highly recommended.

Water Chemistry: Extremely adaptable, it tolerates hard water and brackish conditions. Temperature 22-28°C, pH between 6.5 and 8.0.

Space Management & Placement: Ideal for the background of large aquariums due to its height (growing up to 40-50 cm). Avoid transplanting once established as roots are sensitive.

Pruning: Prune damaged outer leaves near the base of the rosette. Control propagation by cutting and removing daughter plants developed on runners.

Risks & Diseases: Susceptible to Cryptocoryne melt, where leaves decay rapidly following sudden changes in water parameters or lighting.
