Now that I know a puffer is out of the questions what are some suggestions for an oddball? the stranger, uglier and more out there the better!!...lol Or if anyone knows where I can get a Fly River Turtle in the states
You've got some rather large fish in there already. Assuming all of these fish are still babies, you could get away with adding a Mbu puffer at this stage. As others have posted, it may be a bit of a fin-nipper in the beginning, but this group of fish should grow to ignore eachother. Unfortunately, the Mbu would likely be your only option for a puffer. Most puffers are brackish and the fahaka is far too aggressive. I have had my Fahaka for 8 years now and he is a LONER. He would eat me if I jumped in with him. Overall, I think you could get away with a Mbu puffer with this group of fish with little luck necessary as long as these fish "grow up" together. Just make sure you have ample filtration as these fish you have listed are high-waste fish (Mbu Puffer included). Your tank is more than enough in size to house these fish.

Look into the African Lungfish.....there's a larger "gnarly" fish for you to have.....and hey....if you ever get board looking at him in the tank you could always take him out and hold him for a bit....LOL. My neighbor keeps two of them within his custom system and they are nothing short of a conversation piece...even among the other impressive stock you have compiled.
