The screen on my camera is broken so I never know what I'm taking a picture of until I upload to my PC. So, I tend to take a bunch in hopes of getting something decent. I didn't get anything decent but the lights on my 220 kicked on while I was snapping a few shots of the 90 and 55.
It's just a reflection of one tank in two others. Both tanks in the picture have black backgrounds. I wasn't expecting to see that when I uploaded them from the camera. No trick nothing special I just thought it was neat so I shared it.
