Weird crappie behavior

Several years in a row I've noticed crappie turning sideways around a
dock near the bottom and kind of just hovering there, or just slowly
swimming forward. At first I thought they were in distress, but they
don't act like a fish that's been caught and released or a diseased
fish.

In fact, tonight there were 4 of them doing this in about 4 feet of
water. When I'd wiggle a small jig in front of them, they would turn
right-side up and follow the jig, sometimes tentatively striking at
it. Then, they would again roll over on their sides and move slowly
through the water.

Anyone observe this before?
Anyone know what the heck they are doing?
