Okay, I have to say quite a few things. I'm saying this to all the people on this thread.
1. If someone makes a mistake of buying a tankbuster, don't get all cynical, because those people might not know any better. All they need is the facts. Expletives, insults, and gossip is not necessary.
2. For Sir Alex, I would like to tell you that many commonly kept aquarium fish, such as the Queen Angelfish and the Clown Trigger, do get quite large, and attain a larger size than your suggested foot and a half. Also the world does not need people who loosely use their vocabulary for bad purpose; just because it's in the urban dictionary doesn't mean that you should use it. Livingreefs is supposed to be a friendly website.
3. For overstreetlogan, I do not recommend buying a spadefish. They can get up to 3 feet, and do not keep them unless you have an extra large aquarium. They are not reef safe, but usually eat voraciously.
By the way, nice vid.
