I agree that we usually catch on the drop while casting or jigging.
However, I will say that watching our tropical aquarium fish has taught me that fish can move their eyes some to follow falling food and they will sometimes chase it to the bottom. They frequently "stand on their heads" to search for tidbits on the bottom. One reason I picked this particular type of fish is that they are built like miniature crappie. I'll bet forum members with crappie in their aquariums have seen similar behavior. - Roberta
