The water shaders transparency needs to have the right depth. How far are the fish beneath the water surface? Just a bit more beyond that will be a good setting. The bottom of the shader control window has the density parameters. This will control the coloring; the color here will be more dominate than the surface color based on the depth of the transparency. The density slider allows you to adjust this effect. You can add more color/s functions and vary the density.

I think the last part is also needed. Turn on the shadows. That will allow the ripples to be apparent on the fish. This will increase the render time.

All in all, this is a very good study. I would increase the light spread of the water shader. Let more of the ripples stand out.

I wonder what is causing the fish to appear in that semi mosaic form? It's the only thing keeping this from being a great image.

I think maybe it is the refraction of the water and the shadows of the ripples or algae.

Yossam can you make a test with 5-10 times bigger wave scale .

Not sure if you used here or not but try to use real world scale in TG2.
It will make some things easier to use.

Well... the first one are better but... the reflexion and transparency of the water is not very natural. I am not sure but I think you have in atmosphere a very big and dense clouds. The light on vegetation on the first plan are flat. Perhaps try a test with no clouds if you have clouds in atmosphere obviously.

That might be what I was seing, but unable to pin down.

What I think it was............the bump map was causing weird shadows. I turned it off. I'm still not happy with the water............time to tinker some more.

I think I need to change the lighting, maybe that will help some.  :o

Great work! Reminded me of a render I did way back in 2006 with TG0.9...
