I already have, krichard. Rescued, I feed my other fish peas too so i already knew to peel the peas. 
FINALLY! I think I may have hit a break! All those places I called had no clue who could help me except for the very nice lady at Virginia Zoological Park who sent out emails for me to other curators.
Here's what Craig from Virginia Zoological Park had to say -
I found NONE of this information on the internet. Once I get back home, I'm giving those places a call.
Cross your fins!

Hi,
I received an e-mail while I was on vacation concerning a pacu you may be looking to place. I worked extensively with this species of fish at another facility,and while they are wonderful fish they get really huge! I maintained a school of them in a 55,000+ gallon tank to give you an idea of the space required. In looking for a potential location,the most ideal place(s) I can recommend are zoos and/or aquariums that currently house pacu. My old zoo in Milwaukee (Milwaukee County Zoo) houses them along with the following institutions: Shedd Aquarium (Chicago) and National Zoo (Washington,DC). I believe the Jacksonville Zoo has a large Amazon aquarium where they maintain them,and the Tennessee Aquarium in Chattanooga may also. The message I received stated that fish is ~8 long,which is still quite feasible to ship via FedExOvernight in a Styrofoam boxwith bagged water. Should you be able to find a home for this fish,but need some assistance in shipping the fish,please let me know and I can offer some assistance/guidance as my experience in maintaining fish also involved shipping them from one institution to another.
I hope this helps feel free to contact me if you have further questions.
