Barrier between worlds

Im trying to make a map called World Above & Below
The idea is this 4 players are fishes,4 are birds
The question is this.How can i make the terrain imitates this(Not Explicite)
For example a player choses fish-i want that the player to not see the sky(where the birds are)but just the underwater theme.
And for the birds i want them to not see the water (only when they dive ,they see the water)but just see the sky and the tree branches ,not the roots and the ground

Is this possible in the same map?
Sorry if i wasnt so explicite,but i guess that you figgured that out.Here is a paint to show you what im deliring here

Make the fishes have sub-merge and make the camera lock on to them.

So you'll only see the sea.


With the birds just have the camera lock on.
