Petco does that but it's only up to like 29 gallons.
I was gonna say the same thing. The Petco in my area does 40 breeders in the sale too, but from what I understand the stores that do the 40s only get like 3 for the sale. So they go fast
I would probably go with PVC if you could. It would be cheaper, easier to find and harder to break. If your set on glass i would look on amazon or Ebay for one you could assemble yourself but it will still be pricy.
I've still got 3 glass enclosures in use, but will be cutting down to 2 as soon as I can.
I've been an advocate for glass for years, and I still say glass can work extremely well.
That being said, since I've acquired a few PVC enclosures, I will never buy glass again.
I'll end up keeping my Hognose and KSB in glass, but they're in small enclosures and have very easy husbandry requirements that are easily achieved in glass.
My other is a BP in a 40 breeder. I'm in no rush to replace it, but it's inevitably going to be swapped out at some point.
Besides for the Hognose and KSB I'll only keep glass on hand for quarantine.
I guess what I'm getting at is if you can go PVC it's just a better enclosure. Glass is good, PVC is better.
