Can you imagine try to net a fish out of that thing?
I sort of like the look, but wouldn't want to be the one responsible for figuring out how/where to hang it after filling with water. Might make a nice terrarium, however, and could just be left on the floor. It's certainly big enough to make a statement.
Very cool, but I'd agree that livestock would be a bear to maintain. A planted-only aquarium or terrarium or even paludarium would be kinda neat, perhaps with those glass fake fish or inverts?
