If u zoom in on photo shop you can do the edges then you don't lose any of the fish. This is what that photo of mine looked like b4, so it was pretty easy to black just the bottom. He was at the top of the tank.
If you would like you can pm me and email one of your photo and I'll see if I can get a cleaner edge. I would think prolly the 2nd or 3rd since the look a little clearer but you may choose. Actually you don't need to I got it off here. I may try a different color though as the black will make it hard to see his black.
