General Description
Ranalisma rostratum is a small aquatic plant native to the Asian tropics and subtropics. Its emersed form features roundish leaves with a stalk and short inflorescence, while the submersed form showcases light green linear leaves. This plant forms long runners resembling modified inflorescences, which are conducive for rapid growth.
Aquarium Suitability
Ranalisma rostratum is occasionally available commercially. When kept in aquariums under stronger light, it develops grass-like narrow leaves, growing quickly. Under lower light conditions, it produces longer-stalked leaves of a lighter hue and grows at a slower pace. It is suitable for the foreground, grouping, and ground cover in aquarium setups.
Demands and Hardiness
This plant requires medium-high light levels and thrives in water temperatures ranging from 20-28°C. It prefers iron levels between 0.01-0.5mg/l, nitrate concentrations of 10-50mg/l, phosphate levels of 0.1-3mg/l, and potassium levels ranging from 5-30mg/l. It is unsuitable for outdoor use in colder climates.
Aquascaping & Usage
In aquariums, Ranalisma rostratum is recommended for creating a grass-like lawn effect. Its runners aid in forming a dense and visually appealing foreground carpet, adding a natural look to aquascapes.
Propagation
Propagation of Ranalisma rostratum is primarily achieved through runners. These runners allow the plant to expand laterally, facilitating the growth of new plants that can be separated and replanted to propagate the species.
Habitat and Distribution
Ranalisma rostratum is found in regions of China (Hunan, Jiangxi, Zhejiang), India, Malaysia (Peninsular), and Vietnam. It is a species of aquatic plants belonging to the family Alismataceae within the order Alismatales.
