Did I read what you said right? They introduced them to remove other invasive species? I was always curious why they would introduce a aggresive species like the Peacock in the U.S. I was under the impression they did it for sport fisherman not to remove invasive species, seems to me they would wreck local fauna too! I have only a passing interest in them at this point because I have not the funds to keep them though I do love the coloration on them, what is the largest one ever caught on record?
