Thanks for the feedback, agree with all points, also wish I'd cloned the rogue Neon out as well.
Exif for consideration is
F2.8
1/60
Iso 800
31mm
Shot with a D90 with Sigma 24-70 2.8 attached (I don't own external flash so all lighting is tank lights
Kinda come full circle with aquarium photography, was my first tank that made me buy a bridge camera and sparked my interest in photography, I now shoot less fish then anything else having bought the Nikon Oct 2010
This was for a comp on a local forum.
