Microsorum ‘Thor’s Hammer’ Microsorum ‘Thor’s Hammer’ is a rare and visually striking Java Fern cultivar distinguished by its thick, compact leaves and unique hammer-shaped tips. This bold leaf structure gives the plant a sculptural, almost armored appearance that stands out beautifully in both minimalist and jungle-style aquascapes. Like other Microsorum varieties, Thor’s Hammer is a rhizome plant and should be attached to hardscape rather than planted in substrate. It is extremely hardy, tolerant of a wide range of water parameters, and thrives in low to medium light without the need for CO₂—making it suitable for beginners as well as advanced aquascapers. Its slow to moderate growth and tough leaves make it an excellent choice for community tanks, shrimp aquariums, and setups with fish that may nibble on softer plants. Key Features Rare Microsorum variety with hammer-shaped leaf tips Thick, compact growth with bold texture Extremely hardy and low maintenance Does not require CO₂ Rhizome plant – ideal for rocks or driftwood Shrimp-safe and community-friendly Care Requirements Difficulty: Easy Light: Low to Medium CO₂: Not required Growth Rate: Slow to Medium Placement: Midground / Background / Hardscape Temperature: 18–28 °C Planting & Care Tips Attach to rocks or driftwood using thread or aquarium-safe glue. Do not bury the rhizome, as this may cause rot. Occasional liquid fertilization will support healthier growth and improved coloration.
