General Description
Salvinia oblongifolia, classified under the family Salviniaceae, is the largest species of Salvinia, featuring leaves that can reach up to 6 cm in length and 2.5 cm in width. Originating from Central and Eastern Brazil, this floating fern was first cultivated in Germany in the early 20th century but faced a period of disappearance until it was reintroduced in 1995 by Professor Elias R. de la Sota from Argentina. The plant thrives in shallow stagnant water bodies and is characterized by its attractive appearance when provided with nutrient-rich water, high temperatures ranging from 27-29°C, and ample light.
Aquarium Suitability
Salvinia oblongifolia is considered suitable for aquariums, with an availability that is occasional in the commercial market. Its ease of care and fast growth make it an ideal choice for both beginner and experienced aquarists. The plant's demands and hardiness are detailed in the provided table.
Demands and Hardiness
Salvinia oblongifolia exhibits a fast growth rate and does well in environments with medium to high lighting. It thrives in water temperatures between 24-28°C and shows tolerance to temperatures ranging from 18-32°C. The plant's requirements for nutrients such as carbon dioxide, iron, nitrate, phosphate, and potassium are within the established ranges, making it relatively easy to maintain in a suitable aquarium setup.
Aquascaping & Usage
In aquariums, Salvinia oblongifolia can be used for its aesthetic appeal and functionality as a floating plant, providing cover and shade for aquatic inhabitants. Its ability to create a natural and lush surface cover enhances the visual appeal of aquascapes while potentially aiding in nutrient uptake and oxygenation in the water column.
Propagation
Propagation of Salvinia oblongifolia can be achieved through various methods, including fragmenting the plant, splitting, or cutting off daughter plants. This accessibility to propagation allows for the easy expansion of Salvinia oblongifolia within an aquarium environment, enabling aquarists to maintain a healthy and visually appealing display over time.
Habitat and Distribution
Salvinia oblongifolia is native to the regions of Central and Eastern Brazil, where it typically inhabits shallow stagnant waterbodies. This floating fern prefers nutrient-rich waters and high temperatures for optimal growth. While it may develop a smaller dwarf-like habit if conditions are less favorable, providing suitable conditions will allow Salvinia oblongifolia to flourish and showcase its full potential as a striking addition to aquatic habitats.
