Glossostigma elatinoides (Glosso) is a highly popular, small, low-growing aquatic carpeting plant, ideal for aquarium foregrounds, known for its tiny, vibrant green, opposing leaves that form lush mats when given high light, sufficient CO2, nutrient-rich substrate (especially iron), and soft water, otherwise tending to grow tall and spindly. It’s a fast-growing, demanding plant that thrives in planted tanks, forming dense lawns for an aesthetic “nature aquarium” look, requiring trimming to maintain shape.
