Origin

Cryptocoryne ciliata is native to Southeast Asia, growing in freshwater and brackish tidal zones from India and Sri Lanka through Thailand, Malaysia, Indonesia, the Philippines, and as far as New Guinea. It thrives in mangrove swamps, slow-moving streams, and riverbanks, where it often experiences fluctuating water levels.

Growing Conditions

This species is unique among Cryptocoryne plants due to its ability to tolerate brackish water. It is well-suited for both submerged and emersed growth, adapting easily to different water levels. When submerged, its leaves are longer and more delicate, while in emersed conditions, they become thicker and more rigid.

Cryptocoryne ciliata prefers a pH range of 6.8 - 7.8 and water hardness between 4 - 18 dGH. It thrives in temperatures ranging from 23 - 28 °C (73.4 - 82.4°F). While it can grow under moderate lighting, brighter light encourages stronger, healthier growth.

Planting Area

Due to its large size (up to 50 cm / 19.69 inches), Cryptocoryne ciliata is best suited for the background of an aquarium, though in larger tanks, it can also be placed in the midground. Its long, wavy leaves create a natural, dense environment, providing shelter for fish and shrimp. It thrives in fine gravel and should not be moved frequently, as it can undergo “Crypt melt.”

Propagation

This plant reproduces via runners. The mother plant sends out horizontal shoots that develop into new plantlets, which gradually form roots. Once these plantlets are well-established, they can be separated from the runner and replanted in different locations. In emersed conditions, Cryptocoryne ciliata may also produce flowers, which are rare when grown fully submerged.

Difficulty

Cryptocoryne ciliata is classified as medium difficulty due to its slow growth rate and sensitivity to sudden environmental changes. While it is generally hardy, stability is key to its success. Frequent relocation or large fluctuations in water parameters can trigger “Crypt melt”, where the plant sheds its leaves before regrowing.

Short Description

Cryptocoryne ciliata, commonly known as the Mangrove Water Trumpet, is one of the few Cryptocoryne species that can tolerate brackish water. It is available in two varieties: Cryptocoryne ciliata var. latifolia and Cryptocoryne ciliata var. ciliata, with the latter growing larger and more vigorously. This plant is well-suited for background placement in aquariums, where its long, wavy leaves add a lush, natural feel. Given time to establish, it grows steadily and requires minimal care, making it a unique and valuable addition to freshwater and brackish tanks.
