That's the one good thing about splendens, they can display really well in an empty tank with good lighting and a mirror.
I would love to get some nice clear shots of my fish sans all the equipment and dodgy backgrounds, but mine never display well in anything but their own tanks. For me, lighting is an issue as because of the amount of tannins I use the tanks are very dark. Then when I go to put the strong light over the tanks to compensate all my fish go poof.
I have to say having a good camera definitely makes up for my lack of photography skills. My point and shoot was lucky to give me one good shot for ever 100 I took. My mum's canon on the other hand, tends to give decent shots even if I just point it at the tank and press the button.
This is probably one of the best couple of photos I have taken.
I am lucky in that the killifish displayed well even under bright light and that the green provided a nice contrast to their colouring.
