Hi bros, i've been struggling to take a shot of my arowana on an aquarium but failed miserably :cry:. Problem is the reflection on the glass. If i dont use flash (built-in) the picture is too dark coz i'm using fast shutter speed to freeze the movement of my fish . Can you recommend the best camera set-up for the job? I only have a nikon d80 kit lens (18mm-135mm) and a 50mm f/1.8. Don't have an external flash unit. Thanks.
