Microsorum Mini – Microsorum pteropus 'Petit' Aquarium Plant

Microsorum pteropus 'Petit', also known as Microsorum Mini, is a compact variety of Java Fern prized for its narrow, gently wavy leaves and attractive green foliage. Smaller and more delicate in appearance than traditional Java Fern, it is an excellent choice for adding natural texture to freshwater aquascapes.

With a typical height of 10–25cm, Microsorum Mini is particularly well suited to smaller aquariums, detailed aquascapes and planting around rocks and driftwood.

Appearance

Microsorum Mini produces slender, deep green leaves with a distinctive wavy appearance. Although similar to Microsorum pteropus 'Narrow', the 'Petit' variety has more pronounced undulations along its leaves, giving it a softer, more textured appearance.

Its compact growth habit makes it ideal for creating natural-looking clusters of foliage without overwhelming the surrounding hardscape.

Lighting & Growth

Microsorum Mini is a hardy, slow-growing aquarium plant that thrives under low to medium lighting.

CO₂ injection is not required, making it an excellent choice for low-tech aquariums and beginners. Like other Java Fern varieties, it grows from a rhizome and absorbs nutrients directly from the water column.

How to Use

Microsorum Mini is best attached to aquarium wood or rocks using aquarium-safe glue or thread. Over time, its roots will naturally attach to the hardscape, creating an established appearance.

Its smaller size makes it particularly effective in the midground, around the base of larger wood formations or tucked into gaps between rocks.
