General Description
Bolbitis heudelotii (Bory ex Fée) Alston, commonly known as African water fern, is a species widely found in the African tropics. This aquatic plant is characterized by its creeping rhizome, from which both leaves and roots grow. Submersed leaves are single-double pinnate, transparent, and bottle-green, while emersed leaves are single pinnate, matte green, and firm. The plant is delicate and brittle in structure, with slow growth occurring approximately every 1-2 months.
Aquarium Suitability
Bolbitis heudelotii is suitable for aquarium settings, where it thrives when attached to rocks or driftwood using its stable roots. It is essential not to bury the rhizomes in substrate to prevent rotting. A strong current near the filter outlet, CO2 supplementation, and soft, slightly acidic water promote optimal growth. This fern is an easy-to-care-for plant, making it suitable for beginners in aquascaping.
Demands and Hardiness
As shown in the provided table, Bolbitis heudelotii has moderate demands in terms of lighting, carbon dioxide levels, and nutrient requirements. It can tolerate a wide range of temperatures but prefers them between 22-25°C. The plant is not suitable for outdoor use in colder climates due to its native tropical habitat.
Aquascaping & Usage
With its attractive dark green, transparent leaves, Bolbitis heudelotii serves as a visually appealing addition to various aquarium layouts. It is often utilized as an epiphyte in the midground or background of aquascapes. When combined with driftwood and mosses, dense groupings of this African water fern can create a natural and jungle-like aquatic environment.
Propagation
Propagation of Bolbitis heudelotii is easily achieved through rhizome division or by separating daughter plants. Rhizome pieces with at least three leaves can be separated to create new plants. Occasionally, young plants may also develop on older leaves, aiding in the expansion of the fern within the aquarium.
Habitat and Distribution
In its natural habitat, Bolbitis heudelotii is commonly found attached to rocks or driftwood in spray zones and inundation areas of swiftly flowing rivers and rivulets in the African tropics. It often shares habitats with Anubias barteri varieties, showcasing a preference for similar environmental conditions conducive to its growth.
