I would use maybe a few of the common ones like rainbow darters, green sunfish, largemouth bass, SRBD, gambusia, and a few others, or doOK, I think it's time to set up a REAL poll using the forum polling feature.
So...
What should the categories be? Don't want to list every species, but don't want to be too general either.
I'll set it up with a little input...
families like Sunfish, darters, killies, gar, etc.
Then based on which category gets the most votes narrow it down that way.
Just my 2¢
