ranger raises a good point.

i have also seen crappie on the camera sitting motionless, barley moving a fin. we had to bump them to get them to slowly swim off a bit. then they would stop sometimes just in view still. cant always make them bite. some people down size, some find other schools, some go to bass or cats.... and others go home to mow the grass. lol thats fishin. ill blame the weather or currents usually
