Following the antics of two brothers-in-law as they run the largest aquarium manufacturing company in America, Tanked returns to dunk viewers into the high-decibel business of Acrylic Tank Manufacturing (ATM). ATM is led by brothers-in-law, business partners, best friends and rivals Wayde King and Brett Raymer and is housed in a state-of-the-art, cavernous facility located in the Entertainment Capital of the World, Las Vegas. The team builds some of the most outrageous, larger than life and one of a kind tanks for some of the most striking fish and clients around. No job is too big, too far, or too outlandish as Wayde and Brett travel the world to make fellow fish enthusiast's dreams of having their own little piece of the ocean a reality. This season comedian Tracy Morgan brings the Wayde and Brett a big idea – he wants to be able to swim with his massive 1.8m sharks, so asks the guys to tank his entire pool house! Meanwhile health expert Dr Oz gets a tank straight out of a fairytale with an Oz themed interior that has the fish swimming down a yellow brick road; MMA fighter Urijah Faber wants to bring a little bit of the ocean to his new gym – puffer fish and all, plus more.
