Very nice tank indeed, and welcome. I agree that the stones are a little too white, so I'd consider getting mail order riccia or using our "sell and swap" section. Someone's often got some in there. My only other idea, is that your neons and rasboras look great in the midwater areas, but I feel your surface or substrate could do with some activity. Of course, there could easily be fish in there that weren't photographed, but I'd suggest some hatches or something like that at the top, and corydoras, or other peaceful catfish at the bottom to complete the picture.
