Gotta admit, I spend a lot of time catching perch (bluegills) with nightcrawlers.
For what it's worth, I can catch bluegills on nightcrawlers, pellet flies, and midge type topwater flies. I can catch them for awhile. Then, no matter what I do, they realize that there is a string attached and ignore my offers. However, they keep hitting the real pellets. I do occasionally, but rarely, catch a really big bluegill.
No matter what the size, I never measure them. I return them to the water ASAP. They seldom take a pellet fly deeply but always swallow my homemade pipe cleaner sinking flies.
