Thanks for all the suggestions! My only worry about Java Moss is that I've heard it takes over the tank, but I assume I can control that by just pulling some out when it starts going where I don't want it
. I had never heard of fissidens or dwarf sag. I looked up some pictures and they both look like great option, but the fissidens look like they will create more of the carpet look I want. I'm trying to create an area that might allow a shrimp or two to survive in my tank. I wonder if I could do a combo of the dwarf sag with the mosses or will one of the varieties just crowd out the others?
