I'm not sure what normal would be, but several of us have had the same
conversation almost every time we collect where the ranges of the two fish
overlap. Sometimes the differences are subtle, but in this batch the spots
on the F. olivaceous are more pronounced (particularly in the fins) with
the black lateral line more uneven. The F. notatus from the same site are
evenly striped with no spots. I don't know how others deal with it, but for
me, as the fish grow larger the F. olivaceous seems to have a flatter head.
The real dilemma for me is the one I got from Red River that I can't ID. It
is similar in marking to the F. catenatus, but it has a rounded head and
spends most of its time on the bottom. The F. catenatus are already getting
relatively tame, but this other one still likes to hide. What other
topminnows are in that range? I've definitely ruled out F. stellifer.
