I quit trying to figure out fish (and fisherman) a long time ago. Who knows why they strike what they strike?
None the less, I have been having a lot of fun trying to capture the hues of the threadfin shad with a chunk of wood and paint.
I've even gone as far a bringing my camera on the waters and taking a few pics.
In this one, you can see the hues and patterns of the threadfin, which is a major food source for a variety of fish:

As you can see, painting the creature is more than a bit of challenge. The individual scales are multi-hued and some are just plain multi-colored. To make matters even more interesting, it changes colors as the light changes. Even in a constant, stable sunlight, it changes colors as it moves, flashing gold and then silver and then blues and even black.
Note that the spot is forward and high, about even with the eye. Also not the eye is very far forward near the nose. The pupil is not really teardrop shaped and is rather large.
It is a common fish in many freshwater bodies of water, but I think its one of the most beautiful.
