rock size/weight question?

[id10t]

Part of the reason I canceled the Big Rock is that the tank isn't supported on the glass underneath... on top of that, She Who Must Be Obeyed is a redhead *and* Puerto Rican. I would be in fear for my life if 30+ gallons of water, fish, etc. ended up on the floor.

Said tank with a few danios in it - SWMBO likes the idea of cichlids, so thats where it is headed I think...

Looks good. If I remember reading correctly it is actually better if you don't support a glass tank on the bottom because the "weight" is carried on the outter edges. Acrylic on the other hand needs the support because it flexes. Correct me if I'm wrong.
