I would also go acrylic.. I had a 240 gallon all glass aquarium.. until a guy helping me moved it just dropped the corner with no warning..
I know some people have huge glass tanks, but I'd rather go smaller (if I had too) and get acrylic..
It took four guys to move the glass 240 (from glasscages, also), and it was hard work.
Then I got a 300 gallon acrylic.. My wife and I can move it with no straining at all.. It's incredibly light in comparison, and if wife drops it, it won't break, preserving our marriage

lol thats funny. but, i just got a 130ish gallon acrylic tank and had 2 people that were on steroids move the thing (had 9 stitchs in the thumb and couldn't risk popping them open) and they *****ed about the weight of it.
