I don't know the exact words to describe this fish tank; but it hangs on the wall just like a big-screen wall-mounted television would do. It has a frame like a beautiful painting would have, and at first glance, it just looks like a realistic underwater painting------ and then you notice that the fish are actually swimming around in the picture ! ! The company makes these wall-mounted fish tanks in all different sizes, starting with a little round one that is a clock with a betta tank in it, and up to the larger ones that are framed like a painting would be. They are designed to be self-cleaning; so you do not have to spend a lot of time with cleaning the tank, like you would have to do with a regualr fish tank. Look at this quick video, and see what you think . I think that it is one of the most innovative fish tanks ever, and would add to the decor of any home.
