Ever thought about a reflective background?

[Z-Man07]

I am in the slow process of transitioning from my 55g to a 120g with a 75g sump. The black paint on the back of the DT was somewhat scratched up so I just went ahead and scraped it all off. My tank will sit with one long side against the wall and veiwable on the remaining long side and both short sides.

Here is the question: Has anyone ever thought about, and would like to share, the pros and cons of possibly doing a reflective background to facilitate seeing behind the rocks in a three sided tank?

I have given a little thougt to the idea and what I can think is that it would have to remain clean for one. That is OK with me because I do not like the look of anything on the back. I had thought that a "smoked" mirror would be nice.

Would the fish fight with the reflection? Or would they get used to it after a bit?

Any helpful thoughts, ideas or comments would be appreciated!
