Thanks JustLooking , yes I painted the bottom. It was easier to just mask of the edge glass pieces and leave the trim and bottom glass exposed so I could paint it. I think the the black trim and black bottom make the tank look 10 times better, helps that the home made stand is black also. Since the two tanks turned out pretty well, I need to hurry up and build a stand for my 180gal and paint the wood trim and bottom glass in black.
