this may be just a feeling but i think the tanks petco run on sale are different. I may be wrong here. But i have drilled a million tanks of all sizes and have recently cracked one. So a guy asked me to punch a hole in a 20 long he picked up on sale. The tank cracked, feeling bad about it i grabbed one of my 20s also made by aga. The glass didn't seem thicker but felt different when drilling. This gave me a thought that thy are made from different grade glass.

The 40 I just grabbed is an Aqueon with thicker glass than the 29s. I get what you're saying, though I'm sure the manufacturer and distributor would likely NOT own up to any differences. For now we'll have to stick to our anecdotal findings.

The tanks I've been using were definitley subjected to the stresses, of what are plainly seen in retrospect, of poor design and assembly by yours truly. So who's to say?

As The World's Most Interesting Man might say,"Drill safely my friends.".
