Only tempered glass shatters, plate glass does not...sodenoshirayuki;2692962; said:Glass shatters when it breaks while acrylic doesn't.
And who ever said that acrylic is that panty waisted is wrong...it takes a considerable amount of ABUSE to scratch, and nothing associated with aquaria will damage it beyond repair...
when you scratch glass with your sand or gravel it is very difficult to remove those scratches...
