here's a key of florida freshwater fish that settles it for me-in-least-
http://www.flmnh.ufl.edu/FISH/southflorida/everglades/marshes/fishkey.html
If you don't want to run the whole key, just go down to #52 that has
the differentiation between obesus and gloriosus
gloriosus has 5 or fewer indistinct bars, which obesus has more than 5
bars that are more distinct.
the other differentiation is the number of scale rows around the
caudal peduncle, but I have rarely found live fish that will sit still
for that kind of counting.
