I honestly wouldn't want any of your fish accept for the guttulatum but I sure as hell wouldn't replace any of them with some boring africans that are going to take 5 years to mature. Oscars and jack dempseys are just too common so I could see why you were bored with your setup.
What about the Jag? Would you keep the Jag or get rid of it. I got $40 trade in for the Oscar and the Gar, so not too bad. I feel a bit bad about getting rid of the Oscar though. He was pretty messy though. And as you mentioned, very common.
Here is a very bad picture of the JD that I kept. The picture doesn't do him any justice at all, but you can get an idea of the pearls. They are actually bright blue, but my camera/flash makes him look gold.
