I'll do the java moss. I'll be home in a couple days I go out of town for work quite often so I will see how much guppy grass I have and post a pic of it up for you friday or Saturday so you can decide how much moss you are willing to trade for it and if it is gonna be wort our time. I'll ship it in the smallest flat rate box I can fit it in on Monday. We will have to exchange shipping info via pm.
