I sure am glad I feed my Tilapia! If my wife sees the BlueGill she'll NEVER go into the tilapia room!

As far as I know this damage occured on a 6 hour flight in total darkness, but more likely it happened shortly after being bagged.
Think Tilapia aren't tough? This guy only had a small bone where his tail was and lived over a week that way and never had a sign of fungus or infection.
