How come we never hear about such occurences ? I'm not arguing against the
sensitivity to scratches, but several of the most popular mid size tanks 
nowadays are made with a tempered glass bottom pane as standard. With so 
many marine aquariums around with their scratchy sands and coral, we should 
be hearing about catastrophic tank blowouts, not just leaks, shouldn't we ?
