drawing/ parent child layers

Simple Beginner Question:

I have drawn a fish with google eyes. The fish is a layer and the eyes are a layer. When the Eyes layer is stacked above the Fish layer I can see them. Great. When I try to animate, I create a parent-child relationship between the layers so when I move the Fish layer the other layers, or parts of the fish move too(eyes, tail, etc). This also seems to work except, if I put the Eye layer below the Fish layer, to make the animation work then I cant see the eyes. They are underneath the Fish Layer. How can I fix this?

Thanks.
