Honestly, they all are a little scratched. Looks like there may have been sand in a Magfloat or something. There is one larger one on the front that may have came from a rock move or similar. Most friends that have looked at it don't even see the scratches until I point them out. I wanted to use this for a reef setup and the scratches would bug me, but I am pretty picky when it comes to stuff like that. I have seen other tanks that are more scratched than this one.

Let me try and get some pictures and see if they show up...
