I filled it with water when I got it and it didn't leak, but I only had it in there for about an hour. The glass looks kind of thick to me...but I jut can't get to it to measure it to be certain. Sure would be messy if I was wrong
The only thing that makes me doubt that it is an aquarium is the fact that all the tiki style tanks I can find images for on the internet are decorated as terrariums/vivariums. I have yet to see one set up as a fish tank.
Thanks for the info on the strip at the bottom of the tank, just wasn't sure what to make of that thing.
