Microsorum pteropus "Taiwan"

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Should be affixed to hardscape elements like rocks or driftwood using string or cyanoacrylate gel. It is best suited for the midground or background depending on the tank's dimensions. Never plant the horizontal rhizome into the gravel or soil.

Botanical form

Rhizome

Characterized by broad, robust leaves that are deeply lobed or winged, giving it a somewhat palm-like or trident-like appearance. The fronds are sturdy and dark green, growing from a thick, creeping rhizome. It often grows larger and wider than standard narrow leaf varieties.

Growth

Slow

Grows at a slow to moderate pace, making it a very manageable plant for beginners. It may take some time to acclimatize and begin producing new leaves after being introduced to a new tank. Once settled, it provides steady, reliable growth.

Substrate

None

Microsorum pteropus "Taiwan" exhibits classic epiphytic behavior, completely ignoring substrate nutrient profiles in favor of water column feeding. Its fleshy rhizome must sit above the substrate line, as burying it will cause rapid deterioration and plant death. For best results, tie or glue the plant to rough driftwood or lava rock, allowing its fibrous roots to weave into the porous surface over time.

Column fertilization

Recommended

Relies entirely on the water column for its nutritional intake. Regular dosing of a complete liquid fertilizer ensures the leaves do not become transparent or develop holes. Potassium is particularly important for maintaining the structural integrity of its broad leaves.

Root fertilization

None

Root tabs and nutrient-rich substrates provide no benefit, as this plant is an epiphyte. The roots are meant solely for gripping surfaces and will rot if buried. Focus entirely on water-based fertilization methods.

Trimming

Occasional

Prune by cutting off the oldest, largest, or most damaged leaves at their base. Removing excessive growth helps maintain the desired shape and allows light to reach the newer, smaller leaves. Never cut across the middle of a leaf, as it will simply die back.

Propagation

Cuttings

Propagation is easily achieved by dividing the rhizome into pieces, ensuring each piece has healthy leaves and roots. It also reproduces via adventitious plantlets that sprout on the margins of mature leaves. These can be plucked off and attached to new hardscape once they are large enough.

Sensitivity

Moderate

Robust and forgiving, it handles low light and lack of CO2 very well. It is susceptible to rhizome rot if planted incorrectly in the substrate. Like many Java ferns, older leaves may naturally develop black spots which are harmless.

Layout role

Epiphyte, Midground, group, accent

Creates a bold, dramatic statement in the aquascape due to its distinctive leaf shape. It is fantastic for creating dense, jungle-like areas in the midground or background. The deeply lobed leaves offer great textural contrast against fine-leaved stem plants or grassy foregrounds.
