.... but my answers where just what I've seen and experienced here. Others' perspectives are obviously different than mine, and I hope somebody chimes in if anything I've said is wrong.
Al,
IMO great post! I really appreciate when folks take the time to share their personal experiences. I don't see how anyone can say what you've personally seen happening in your individual pond is wrong. IMO the results achieved by introducing a new species to any BOW will vary and always comes down to, the goals trying to be achieved, the unique attributes of each BOW and the current inhabitants.
Just my 1 cent.....
