I am sure that some light will be reflected back into the aquarium by the glass sides, most of it must escape otherwise i dont think we would be able to see inside the tank. As for the black back i dont think it would make much difference if it was painted on the outside of the glass as the photons would interact with the glass before the paint. If the back was colored with acrylic i am sure it would absorb more light than if it were clear. thats my 2cents
