Willow moss is just a bit more, well, willowy than java moss, and both make beautiful live ground cover. Mosses are a welcome home to smaller aquatic critters such as fry, fancy shrimp, and freshwater crabs. We ship one half-full standard betta cup portion with each order, enough to cover the bottom of a typical betta tank. We recommend the addition of willow or java moss to any fancy shrimp tank.
