Three light setup with cyber syncs, for a long time I've used a Styrofoam box to reflect the light into the tank but always ended up with unwanted shadows, so tonight I played around with a lights a little bit and realized portrait photography can be used as well. Creating a rim light to fill the sides of the fish has yielded some very nice results.

Setup is two speedlites side to side, and one alienbee B800 from the top. There will be a lot of light to penetrate the water depending on the depth and distance so apature will vary.

Here you can see the speedlites from side to side lights up nicely.

Quick and easy results with less than two minutes of editing to delete a few micro bubbles.
Enjoy, Thanks!
