A romance with demi-human creatures in a mysterious abandoned aquarium.

Intro
Now, if I proceed through the passage from the marine mammal zone, if my memory serves me right...
A familiar iron door to the back area and embedded tanks. The coral reef zone.
As expected, the coral has grown, the iron is rusted, and the carpet on the floor has faded. It's much more... wild than the aquarium in my memories.
Now, where should I start looking? The tropical fish tank? The mantis shrimp tank? The circular sea turtle tank? Or should I head into the back area?
