Photo cleanup

This photo was taken in September of 2010 in a classroom.
This is the original photo uncorrected. I used fast moving for the scene selection with the flash on as well.

This is the same photo above that has been corrected by using spot healing brush, and the patch tool as well.
I tried many things like spot healingand the  patch tool to make the blurr disapear from the photo when i removed the black cords, but nothing worked.

This is the same photo as the two above, with the same corrections plus I adjusted the levels of light.
I like this corrected photo better because the colors of the fish seem more vibrant.
