Looking at the fishes northern distribution range...this looks about right.

However, clearly this is a sub-tropical species that "prefers" water
temps. much milder.(Check out the dots througout Florida on Freshwater
Fishes of North America 1980).

Any comments? >>

It seems as if the northernmost populations would have the most cold
tolerance out of all the H. formosa populations.
