Norm,

Caught a rainbow about the same size as your photo fish earlier this year in my favorite small mountain stream. Had let the foam ant I tied drift through a run and was starting a little roll cast when I felt a heavier then usual weight on the line. Looked back just as the ant lifted from the water with a wee fish attached to it. Laughed hard enough to scare any fish left in the run. Had to be very careful in releasing it cause it was so small. I didn't want to handle it and couldn't anyway. Luckily, was using barbless hooks and was able to gently wriggle it off.
