I recently acquired 2 fish from 2 separate lakes in my area. One is a full grown green sunfish, and the other a white bass. While looking at them today I noticed the green had a 1/2 inch long parasite on it's fin. It looks like a clear leach with a grey stripe through it's core. I then looked at the white bass, and he also has many smaller white parasites on his dorsal fin. I know one of the two local lakes lost all fish over 20lbs or so to a parasite. The other lake had no reports of this parasite. As far as I can tell, the smaller ones on the bass look white, but they are much smaller than the one on the sunfish. The bass also has at least 15 or so on it's dorsal fin. These fish are in seperate tanks, and have not come out of decontaminiation yet. I have no idea how to deal with this kind of thing, and any help would be greatly appreciated.
