Native to the rivers, streams, and waterfalls of tropical Asia, this tough, adaptable water fern has been a cornerstone of planted aquarium keeping for decades, beloved by beginners and experienced aquarists alike for its extraordinary hardiness, striking appearance, and virtually indestructible nature. Growing to 6–12 inches (15–30 cm) tall with broad, lance-shaped dark green fronds, it brings a bold, natural, jungle-like quality to any aquascape.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSold here in a 5 cm pot, ready to attach to your hardscape or place in your aquarium straight away.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePractically Indestructible\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eJava Fern is one of the very few aquarium plants that genuinely thrives in almost any conditions — low light, no CO2, a wide range of water parameters, and even in tanks with plant-eating fish that would devastate softer-leaved species. Its tough, leathery fronds are left alone by virtually all herbivorous fish, making it one of the most reliable and practical planting options available regardless of what you keep.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCare at a Glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eScientific name: Microsorum pteropus\u003c\/li\u003e\n\u003cli\u003eAlso known as: Java Fern, Asian Water Fern\u003c\/li\u003e\n\u003cli\u003eOrigin: Tropical Asia\u003c\/li\u003e\n\u003cli\u003eType: Rhizomatous — epiphytic water fern\u003c\/li\u003e\n\u003cli\u003eGrowth rate: Slow to medium\u003c\/li\u003e\n\u003cli\u003eHeight: 6–12 inches (15–30 cm)\u003c\/li\u003e\n\u003cli\u003eLight demand: Low — grows in virtually all lighting conditions\u003c\/li\u003e\n\u003cli\u003eCO2: Not required\u003c\/li\u003e\n\u003cli\u003eBest placement: Foreground to background depending on size — attach to hardscape for best results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlanting Tips\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eJava Fern is best attached to driftwood, rocks, or other hardscape using fishing line, thread, or aquarium-safe glue.
