Be careful with some of those different mosses that aquaticmagic is selling. The reason you don't see them in other places is because they are non-aquatic. aquaticmagic does have a great selection, but don't take their word or their pictures at 100% face value -- several of their selections are not meant to grow in your aquarium; they will die if submerged for an extended period of time. Star moss is one example of that.
