Why the Kitchen Smells Like dead Fish

Last week one of my clownfish, Marlin, decided he was tired of tank life and made a run for it. I guess he forgot about the whole having gills thing and Heather found him the next morning in the middle of the kitchen. He made it a good ways before he died. So this is the new fish I got. She is a Sailfin Tang. I havent been able to come up with a name yet though.
