Riccia fluitans, commonly known as floating crystalwort, is a versatile and popular aquarium plant that adds a touch of natural beauty to any planted tank. This bright green, liverwort species is known for its delicate, moss-like appearance, with tiny, branching fronds that form dense mats. Riccia fluitans is highly adaptable and can be used in various ways within an aquarium—either as a floating plant on the water's surface, where it provides shade and shelter for fish and shrimp, or attached to rocks and driftwood to create a lush, green carpet or accent. Under high light and with CO2 supplementation, Riccia fluitans grows rapidly, making it an excellent choice for aquascapers looking to create vibrant, living textures in their underwater landscapes. Its ability to absorb excess nutrients also helps in maintaining water quality, contributing to a healthy and balanced aquarium ecosystem
