As I've told in another thread, I've just used my strobe for the firs time. Resulst are not too bad for macro and colour fishes, better than what I expected, but in silvery fishes annoying relfections appear. I think that it could be because the strobe is in a frontal position here, but I'm not really sure. How can I improve the lighning in pics of silvery fishes? How would you aim the strobe to reduce those the reflections?
This is the pic:

The distance between the school and me was about 1 - 1.5 meter. I used a diffuser.
Thank you in advance
