It is interesting. These must come in quite a wide array of variation in colors. I have never seen a dark blue one, with an orange tail like that. TX Fish and Game, and the DNR have partnered and release Tilapia from what I am told, I haven't verified that statement, but have read it on several fishing forums, but the agents at the Athen's fish hatchery told me that the Tilapia were released around San Antonio in an effort to provide a forage fish to boost the size of Bass and other sport fish.
At first I left this blank...but now I believe: "It's better to keep your mouth closed, and have the world think your a fool, than open it and confirm it."
