Thanks guys! Leopardess, I totally agree with what you are saying. The left side is the "weaker one." The R. vietnam is looking rough, as I had it floating for a couple of days--it was in the mail for 6 days! I think the corners need some filling, but I'm not sure with what yet; Blyxa might be neat on either side, but I'm not sure I can grow it. I think I'll let it grow in a bit, get the rocks out of the way, then decide.
