There are videos on YouTube that show minnows suspending off bottom barely moving. Further on in the video, minnows are changing direction constantly like something is up.If I could upload the video you'd see what I mean.
Now I'm not one to give a hoot about what looks natural when it comes to lures (99% which
don't move nor look natural nor like anything fish eat). But the video does give one some perspective when it comes to the way fish act: from suspending and barely moving to a nervous energy that is getting them ready for flight or attack.
The usual scenario:
A lure passes through their strike zone interrupting their slumber and the bully in fish takes over. The more
nervous the lure's action, the more the predator senses
vulnerability. Not knowing or sensing what a lure is, creates a vacuum between its ears while at the same time propels it to stop the irritating object from moving.
Lures iMO do just that:
trespass, irritate and provoke an attack. All the rest of the stuff that assumes anglers know
why fish strike certain lures makes assumptions not based on proof or fact. The more lures you or I catch fish on, the more we must take into account the technical side of lures:
lure size, shape/action and presentation. On top of that, most lures are
not versatile - soft plastics the one category that is.
The lures shown exhibit different
actions -
all of which provoke bullies-with-scales to strike, from 5" bass to 7 lb catfish. I can catch over 50 fish/day using just
one of them. You got a favorite lure; I got over 200 favorite
lure actions and have kept records going back 40 years.
At first, only pen and paper,

and then a digital camera which logged far more information such as:
lures and the fish they caught
water quality
day and year (season)
sun or clouds
wind and waves
cover, depth (sonar shots), a record of specific areas of a lake, etc.
Catching fish
consistently relies on facts - not assumptions of what prey simulations fish are more apt to strike. Photo logs don't lie.
