Am I correct in assuming that the tank is a standard rectangle? I am planning to get one of those for my WCMM (hopefully tonight.) I would love to hear some suggestions as well. Some things that I have been told are: Hemianthus Micranthemoides, petite nana (I have one of these in my 2.5g hex and it is beautiful.), R. wallichi, Hemianthus Callitrichoides, dwarf java fern, Mayaca, any of the mosses. I don't know much about many of these. Do you have pics of your current scape yet? What kind of top do you have on it?
