Cryptocoryne spiralis, also known as "water trumpet," is a species of aquatic plant in the family Araceae. It is native to Southeast Asia, where it grows in slow-moving rivers, streams, and marshes.
Cryptocoryne spiralis is a tall plant that can grow up to 30-50 cm (12-20 inches) in height. It has long, narrow leaves that are typically green, but can also have brown or reddish tones depending on the lighting and water conditions. The leaves grow in a spiral pattern from a central stem, giving the plant its characteristic appearance.
In aquariums, Cryptocoryne spiralis is often used as a background plant due to its height and attractive form. It prefers moderate to low lighting and a nutrient-rich substrate, but can tolerate a wide range of water conditions. The plant can be propagated by dividing the rhizome or planting the small plantlets that grow from the mother plant.
Overall, Cryptocoryne spiralis is a popular choice among aquarium hobbyists for its tall and striking appearance, as well as its ease of care and adaptability to different water conditions.
