I agree, I would suggest mounting the light off to the side or on the side. Actually if you didn't mind taking a chance, you could take a small metal rod and bend the ends down, cut out the center brace leaving a nice piece of plastic to drill a hole through on both the front and back of the tank, and put the bent down portion of the rod into each hole as a support. But the plastic may be brittle so if you try that be careful, the metal rod needs to be just the right size to just barely have pressure on it.
