Live Tropical Moss if you want it sooner, break out the yellow pages and start calling every garden center within about a hundred miles or so....lol seriously though, a pet store that is planted tank friendly will have java moss. i use coco fiber in my vivs. sometimes eco-earth, sometimes a brand made for hydroponics. all depends on the viv, the location of where the moss is going, ect. occasionally, you can find flower shops that have live mosses. good luck in your search
