After the big freeze in '09 for us in South Fl, the exotic fish were really affected. Many were killed off. The glades back then had a healthy population of pea's, oscars, and mayan cichlids. They are slowly starting to rebound. I have not caught a peacock or heard of anyone catching peacock out there for a very long time. However, on my last trip to the glades I did see a juvenile pea swimming around. As far as eating, there has been a bulletin out for a while now, cautioning people on the amount of fish caught in the glades due to high mercury levels. You will have better luck fishing for pea's in your local canals than out in the glades.
