Admission & Hours

Welcome to the Aquarium

A home to thousands of species, coral reefs are one of the most biodiverse environments on the planet. They also serve as fish nurseries, providing protection, food and shelter for young scaly swimmers.

The Aquarium Gallery at the Butterfly House & Aquarium displays hundreds of different species of fishes and corals in over 10,000 gallons of aquariums. From coral reefs and anemones, to seahorses and tangs, our saltwater exhibits are home to marine life from the Indo-Pacific region to the Caribbean.
