Pond Boss Forums FISH & FISHING Sunfish-Including Largemouth and Smallmouth Bass Strange external parasite?

Without a picture or a specimen my vote is some specie of leech. Do a little more homework on the leeches. There are over 500 species of leeches in 10 families; quite a diverse group. Are you familiar at all with the Piscicolidae? There are also several fish parasitic glossiphoniids (Glossiphoniidae). Is there a discoid head or a proboscis? Numerous leeches are only 6-9mm long and some as short as 2-5mm. There is probably some sort of minute caudal sucker for attachment? Is it minutely segmented? You have a hand lens? Shawn Banks is good with parasites. Maybe he will see this and respond.
