Hi, I am trying to create lighting for a School of fish that looks realistic.I never did under water lighting before. What lights should be used and the list of aov passes should I provide to the compositor to make it more realistic.

I Know I have to use Volumetric lights & Lights with gobos but any further details can be helpful
