I watched last night, and was not impressed. Tangs in a phone booth with no room to swim, TV's in an aquarium... kinda defeats the purpose. But most importantly, like you - I am clueless, other than camera magic how they are doing this without nuking $1000's worth of fish.
Not to mention, people watching are guaranteed to think thats what you do, and there will be a massive die-off of fish because people are adding fish and salt to the tank at the same time!
