I'm no good at individual shots, especially in this tank, but I did add all new rocks, which the fish absolutely love and got a tank shot while shooting photos for selling another tank (the oak one in the foreground)... I'm pretty happy with how it looks, and it was nice and simple to set up - just tossed them in randomly. Was worried having light rocks, light substrate, and no background might wash the colors out but they actually look pretty good.
2nd photo is roughly how it looked before. That's the old 55 (it's a 75 now) but it was basically the same setup.
