A massive wall sized aquarium filled with predatory fish

Lining the far and side walls, this aquarium dead-ends into the back of the museum. The fish that swim inside this single large tank are of a more vicious and hungry type than the fish in the first room, and so are only seen with other fish that can defend themselves. The glass on the tanks seems to be almost one way, allowing visitors to look in but the fish can not peer out, as some of the predatory fish can work themselves into a lather over seeing things they can not hunt.
