Microsorum “Windelov”

Microsorum pteropus 'Windelov', commonly known as Windelov Java Fern, is a popular and attractive aquatic plant in the aquarium hobby. Here are the key details about this plant:

Description

• Appearance: Microsorum 'Windelov' is a variety of the Java Fern with finely divided, lace-like leaf tips, giving it a distinct and ornamental appearance. The leaves are typically dark green and can grow up to 20-30 cm (8-12 inches) in length.
• Size: It can reach a height of about 15-30 cm (6-12 inches) and spreads horizontally via rhizomes.

Habitat

• Native Range: The broader species Microsorum pteropus is native to Southeast Asia, including countries like Thailand, Malaysia, and Indonesia.
• Natural Habitat: It is commonly found attached to rocks and driftwood in shaded, slow-moving streams and rivers.

Cultivation in Aquariums

• Light Requirements: Low to moderate light levels are sufficient for this plant. It is quite tolerant of varying light conditions, but too much light can lead to algae growth on the leaves.
• CO2 Requirements: CO2 injection is not necessary, but it can enhance growth. This plant is well-suited for low-tech setups without CO2.
• Substrate: Unlike many other plants, Microsorum 'Windelov' should not be planted in the substrate. Instead, it should be attached to rocks, driftwood, or other hardscape elements. The rhizome should remain exposed to prevent rotting.
• Temperature and pH: It thrives in a temperature range of 18-30°C (64-86°F) and prefers slightly acidic to neutral water (pH 6.0-7.5).

Care and Maintenance

• Trimming: Occasional trimming of older, damaged leaves is recommended to maintain a healthy appearance. New growth will emerge from the rhizome.
• Propagation: Propagation is done by dividing the rhizome. Small plantlets often form on the leaf edges and can be detached and reattached to hardscape elements.

Aquascaping

• Uses: Microsorum 'Windelov' is often used as a midground to background plant in aquariums. Its unique leaf structure adds texture and visual interest to aquascapes.
• Companion Plants: It pairs well with other low-light plants such as Anubias, Cryptocoryne, and Bucephalandra. It can also be combined with mosses like Taxiphyllum barbieri (Java Moss) for a natural look.

Challenges

• Algae Growth: While generally low-maintenance, Microsorum 'Windelov' can attract algae if exposed to excessive light or if water quality is poor. Keeping it in shaded areas and maintaining good water conditions can help prevent this.
• Nutrient Uptake: As an epiphytic plant, it absorbs nutrients primarily from the water column. Regular liquid fertilization can help ensure it gets the necessary nutrients.

Microsorum pteropus 'Windelov' is a versatile and hardy plant that can enhance the aesthetic appeal of any aquarium. Its unique, finely divided leaves and ease of care make it a favorite among aquarists, especially those with low-tech setups or a preference for epiphytic plants.
