Ive been to the National Aquarium in Baltimore, matter of fact I can just about see it right now out my office window. But have not been back since the Aussie exhibit went in.
I think your thinking of the Amazon Exhibit in the DC National Zoo, yes? It rocks. The PIMA's are the ticket.
Now for your questions.
The Zebra is MUCH more Passive than a Dragon so that would work except they are shrimp eaters..so eventually bye bye Mantis.
Sharks and Rays are bottoms by nature but ask anyone who has kept rays and they will tell you, They go all over. I have owned 3. Up the sides and slide down, across the middle...they are fairly active at feeding time.
The Sharks wouldn't eat the rays the way you think....they would bite at the edges of the disc causing bacterial infections.
Lion would not go after anyone, but he will not get out of the way either. And during feeding time Rays and Eels get pretty active.....it's just a risk.
If I were doing what you wanted I'd do a shark tank with some real active mid water larger fish..ie Large Tangs (Sohal, Naso, Unicorn), Porkfish, or the like. Then in another tank I'd have several Large Lions with a large eel in the rock pile.
I've found in planning all my tanks that with SW it takes a LOT more planning the stocklist and order than with FW. One wrong move can destroy a tank.
I've heard several stories of a 100 clown trigger "Deciding" to kill all his friends and costing 1000's in dead livestock.
