Ashay,
The Bucket shots are of the actual shipment being received. Every fish is pictured. Size, shape, color and patterns are represented right there in one lump sum. No way around it and no tank shot funny business.
With the tank shots the fishes shape is sometimes not represented properly. Depending on the angle of the tank shot, you can make a football fish look normal or a normal fish look like a football. Also if the fish starts to swim the fins may not be errect and poorly represent the fish.
