Great replies and so relevant to what I've experienced. Reminds me of when I would return from fishing with fish in the livewell a few years ago. Bass would line up same way waiting for small panfish to be thrown to them after they saw the truck and boat pulled parallel to shore. Had to be over 9 bass competing for a perch and sunfish meal.
Note: gills steal food from the three turtles and even grab bread right from their mouths if it's sticking out. For the turtles to get some I have to thrown bits of bread on top of shallow surface algae, never in open water. Those fish are like colliding rockets once they hear a splash - even in 1" of water! (Never knew they could swim sideways for food.)
