Thanks Lupin, that link cleared up a couple of question. I will pass it on to my friend. He bought the fish without really researching it. He did google it on his phone, but I don't think that he got a lot of info.
I know he was planning on getting a bigger tank, I just don't think he is ready for how big this is going to become. Also I think he may end up with that being the only fish. He has a small (29 gallon) tank with community fish.
Then I wonder how long it is going to live between how his feeds his fish (it looks like someone shook a snowglobe) and his girlfriend's daughter likes to dump a whole can of food in the tank.
