Beautiful, lush, dense, moss for perfect shrimp scapes, everytime. Moss sucks up nitrates, CO2 and fish waste and aids the filtration in the tank. Because this 100% all natural moss is wild harvested without any pesticides, it may arrive with some brown spots. These spots are perfectly natural and will turn green as soon as the moss adjusts to its new environment and water conditions. Coco Mini Moss has beautiful, small leaves that cluster together, giving it a feathery texture. Easily attaches to surfaces for hardscapes or driftwood bonsai trees.
