I love aquariums, but I can never find a good place to put one. That’s why the closest thing I have gotten to an aquarium is a gold fish in a tiny little fish bowl. Aussie Aquariums has introduced a line of aquariums that mount right to your wall. They are available in various shapes and sizes to fit anyone’s needs and the prices range from $250 to $1000. Installation looks easy enough, but if you live in Southern California, you can get it installed professionally. This is perfect for fish lovers who do not have enough floor space to keep a standard aquarium.   [Gizmodo]
Check ebay, there are alot of these out there from several companies. You can get nice ones for bettas under 50.00 with no air& ligting. But for other fish they range from 100.00-3000.00 shop around!
