The Aquarium at the Silverton Hotel

Within the Silverton Hotel on Las Vegas's famous 'Strip', a 117,000-gallon aquarium is home to more than 5,000 exotic fish, including sharks, stingrays and coral. Of course, this being Vegas, there's a showbiz touch: if you visit the Silverton Aquarium you'll see women in bikini tops and ‘tails' swimming underwater among the fish. These are the aquarium 'mermaids', who perform synchronised routines and blow bubbles. Try to catch feeding time, when divers enter the tank to feed the stingrays while a guide explains what's happening to the audience. And if you are scuba-certified you can even get married in the tank.
