Callicostella prabaktiana

Callicostella prabaktiana is a rare Asian aquatic moss admired for its lush, feathery fronds and deep emerald color. Naturally found on rocks and wood in shaded forest streams, this moss creates elegant, layered textures that soften hardscape and provide shelter for shrimp and small fish. Its graceful, fern-like branching pattern makes it ideal for nature-style aquascapes, paludariums, and blackwater biotopes where subtle detail and movement are key.

Hardy and versatile, Callicostella prabaktiana attaches easily to driftwood, rocks, or mesh and thrives in a wide range of water conditions. With low to medium light and steady nutrients, it forms dense mats that require minimal trimming. Perfect for beginners and expert aquascapers alike, this slow-growing moss adds timeless beauty and natural depth to any aquascape while remaining low-maintenance and algae-resistant.
