I read somewhere (or watched a show) that said that looking at fish is a stress reliever. I go straight to my tanks when I go home from work and stare at it for about 10 minutes.
That is cool however I dont think its a business office. I think that is a class room for marine biology.
And you are right about fish being stress relief.
Actually it was at a software dev company called Freshwater Software www.freshwater.com
They recently (april 2nd) sold to another company, so all the pics are gone
