Innes list 55 to 85 degrees. Alelrod and Schultz say 50 to 90 degrees.
I now have found they can "tolerate" WATER temperatures in the low
40`s, as long as the change is GRADUAL!
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?
