That set up will not work for an aggresive tank. But if it helps I will give you a $100 bucks and take it off your hands.
You can't blame a guy for trying.
I currently have a porc puffer, spotted puffer (which someone else posted a picture of today) and a Niger in a 125.
The Niger is my favorite.
I would say pick one fish that you like the most, and then add others that will go with that specific fish. I am going to add a maroon clown next.
Good luck, and what a great price.
