I know, they do look wrong I agree but in this case it's for a special cause. A tall plant that arches like a val wold also work. If the tank has the right lighting there's no reason you shouldn't try the moss again but I did find that moss on the ground didn't matter it was just what was a divider up top in my case so I don't know what moss on a rock would do.
