First final shot is done. The photo is ok but it can improve a little more. Needs some time till the back fills in more, to have less negative space. But it feels good to have a good picture already in case something happens with the tank. When contests are over I will share the final shot with you guys

Here you can see my setup how I do final shots. I don't use my
twinstar when doing final shot because it will block out light of my external flashes. I use a very small led flood light above the tank so I can still see the position of the fishes. It is a lot easier when you have a hanging kit. It takes a lot of pictures to get that one with the fish in right position. Even after 180 photos I don't have the perfect photo with them all being in a line. The black cardboard is to reduce the amount of light entering in the camera lens.
