In 2013, the Aquarium reopened the Giant Ocean Tank after a ten-month renovation. The new Giant Ocean Tank features a new reef designed to represent a pre-Columbian Caribbean reef, new lighting with the reflective dome, and better views with the new viewing windows along the tank. Additionally, the number of fish in the tank has increased from 800 to 2,000 and number of species has increased from 90 to 140.

Located in the central open atrium of the main building, the principal feature of the Aquarium is the Giant Ocean Tank, a cylindrical 200,000-US-gallon (760,000 l) tank simulating a Caribbean coral reef. This tank houses sharks, sea turtles, stingrays, eels, barracuda, and many smaller reef-living fish.
