In my experience, fish are very opportunistic.

The only thing better than a "free meal" is a free meal that someone else catches for you!

We used to fish a broken rock bluff in a large reservoir. In the spring, the most productive technique was to put on a deep-diving crankbait and crank it down the face of the rocks as deeply as you could. You would get hits during every portion of the descent.

We caught multiple spotted bass on the same bait on many occasions. Further, if you caught a fish at the deepest point, then you would be reeling the fish up from almost straight under the boat. That condition gave you great viewing of your hooked fish and lure coming up. Many times you would have a 12-15" spotted bass on, and there might be up to 5 more spotted bass of the same size following the hooked fish up - I believe waiting to see if the prey would escape, so they could eat it. We observed other bass knock the hooked bass on the way up. The most common way (that we observed) for a 2-fer, was to have a bass on the front hook, and when he got knocked, you sometimes hooked a second bass on the trail hook.

One time, I swam the bass around the edge of the boat at the surface for a bit, and told my brother to flip his beetle-spin to the four bass lurking about 3' below the hooked bass. One bass darted up to hit it immediately!

We almost always did our fishing on that deep bluff after we had fished our best shallow water structures earlier in the morning. Therefore, we had optimal viewing conditions into the deep, clear water with a high sun. Many springs, we could see down 10-15'.

I do not know if the multiple strikes were related to aggressive spotted bass, the unique conditions of THAT fishing spot, or was purely observational bias because we could observe the action so easily.

Maybe the optimal visual conditions even helped the bass to hunt? Feeling a big disturbance of a hooked bass, I assume the fish usually have a fight-or-flight response. However, if the other bass can easily see a large morsel of "food" sticking out of the mouth of one of their buddies, they are then more inclined to join in?

I do NOT know what the community response is if you catch a 2# LMB at the end of your cast in patchy weeds. For example, if other bass follow the hooked fish towards the boat trying to get a free meal? The low angle glare and weeds have never allowed me to see.

Perhaps, when people have drones up above their lures, we will learn more about fish behaviors.
