no, no....
it's not metal-framed (though i had one of those once.. it has a slate bottom, weighs about 50 lbs)
it's all-glass, with the usual black plastic rim and base.
it seems to be a slightly different size than AGA or other 'modern' 29s
the bottom glass is pebbly on the inside, not clear. no mention of tempering, but i'd guess so.
this tank is up and running, no problems. i used it in a dorm room for a few years, but never noticed the sticker on the bottom before.
i'm guessing it was bought by my dad, it's probably the 29 from the corner of the dining room in my childhood home... it had cichlids in it then.
