Hi Tom,
I almost didn't even notice your fish hiding down there. I initially thought there was way too much colour for my liking in your pic in this kind of composition, but now I'm comfortable with looking at it from the point of view of the noticeable colour really being in the flower. Your selective lighting also helps to draw focus to the flower as the main focus of contrasting colour. Your title was effective to encourage me to look around for the VERY subtle touch of orange colour where the fish is hiding, so that added some interest for me. However, overall, perhaps the flower, fish and maybe a few leaves in colour would have worked a bit better for me with the C9 theme.
Cheers, John
