btw i went to a third petco yesterday (in oshkosh) and they had a huge arrangement of like 45gallon high tanks or something. these tanks were still only a foot wide but they must've been close to 3 feet tall. i've never seen anything like it before. and what surprised me was that there wasn't a center brace on the top. i was really really tempted to get one because it would've been awesme to grow out some tall plants, but i was happy with my 40gal breeder and 20gal long. also something about having 4 5gals and 8 10 gals that aren't being used stopped me from picking up any more tanks for awhile. i actually went to a garage sale and saw an aquarium and it was the very first aquarium at a garage/yard/rummage/moving sale that i DIDN'T buy. felt so strange.
