Since we really don't know what crappie see how can we know it disappears for them? Also it may just change to a color they see as gills, or blood saying I am injured.

I posted a link to explain the eyes of some fish like a crappie and we have things called cones and something else in our eyes, but they have more of them. Otherwise how would bass find a black worm being slowly pulled along the bottom at night?

Since we don't really know what they see how can we discount something just because it's the way we see it?

Ah love a good question with lots of ways to look at it.
