I noticed after one of my tank cleanings that there was a small scratch in my glass tank (front about 6 inches from bottom). The scratch is small enough that if you are not looking for it, you probably won't see it (but I know its there... ). Are scratches in tanks, for the most part, inevitable and part of the "owning a glass tank experience"? I've been obsessing about the scratch and not sure I am over reacting.
