Before you fill the tank be sure to consider the back of the tank. A riparium looks best when the back is black, in my opinion, and that can be done by painting the back, or using a black window film on it. If you only cover the portion of the back that goes up to the water line, that is the ultimate for looking good. This is much easier if done before the tank is full of water, substrate, plants, etc.
What bracket is that at the back? It looks very promising for a light support bracket.
