I agree about zebra danios. I may need to over-rule my wife on that one.
Oh, I got the stand today. It had some minor damage, but otherwise looks fantastic... the best looking stand I have seen so far. The aquarium will be just the right size for the spot. The base does continuously touch the floor in the back, and most of the front, so it'll spread the load. I'll keep it away from that seam in the carpet. I put that 14 gallon tank on it just to see, and it is at least right now perfectly level length-wise, and 1/16" off over ~8" depthwise. How close will I need to get it when I go final?
But one thing is disturbing me that I am trying to contact the manufacturer about. There is a slight gap between most points where it connects to the base and where it connects to the top surface. I think the pre-assembled side parts were not alligned correctly by the manufacturer. So no single vertical piece touches both the base and the top... so all the force seems to be shear force through some hinges. I took some photos and will ask them about it.
