I've convinced a couple people, but the best one by far was my wife. Before we started dating, we were coworkers at Petsmart in the fish department. She had always only kept freshwater, while I had a 180 gallon FOWLR, a 187 gallon FOWLR, a 75 gallon FOWLR, and a 32 gallon biocube reef at home, and I would constantly show pics of the tanks, or this new fish, or that new coral, Anemone, or shrimp. She set up an 8 gallon nano just as we started dating, and now she's just as obsessed as I am. Makes aquarium purchases that much easier. Dropped 3x what I was supposed to on corals, and she was only mad until they all opened in the tank.
