I have a hard to light 54 corner and have the same "problem". Here is my tank from the front

and from the top.

Now that you mention it it does kind of look like the grappling hooks are extended and ready to lift the tank up. But since the only other choice is to suspend it from the ceiling or have a custom hood built I am as fine with what I have. I've noticed that people spend far more time looking into my tank than at my tank. I think that most people will just think that this is the way it is supposed to be.
