This is a character I decided to make after seeing a Oranda goldfish in a store one day. I really liked how the translucent bubbles in the fishes head reacted with light and created a sort of foggy blurry image of the insides of the fish. I only spent about 2 afternoons modeling this in Zbrush and I rendered it in Mental Ray inside of 3d studio max. I used various combinations of MR's fast SSS skin shaders and glossy translucency renders. It was a lot of fun since I just did a bust and was able to concentrate on texture/shader creation. The background, fog, rays, bubbles etc were all composited in Photoshop.
