Let your cares melt away as you watch 4,000-plus exotic fish swimming in the colorful Silverton Aquarium. It's easy to lose track of time just by watching these peaceful sea creatures. Fortunately, there are comfortable benches surrounding the aquarium for your lounging pleasure.
  You may wonder how the mermaids breathe underwater, since they're swimming in the tank 15 minutes at a time. Every mermaid is scuba-certified and gets air from hookah ports throughout the tank.
  In addition to the mermaids, you can also sometimes catch divers feeding stingrays. During the feedings, there's a guide outside the tank who'll take questions from the audience. The divers have a built-in speaker in their suit and can answer anything you want to know about the fish.
