Not according to this report from the Florida Museum of Natural
History.

"Dispersal northward in Florida appears to be restricted by
temperature. A 1982 Florida Game and Freshwater Fish Commission study
determined the lower lethal temperature for this species is 12.9° C.
In its native range, the oscar is valued by artisanal fishers as a
food fish."

Thats approx. 55ºF.

I clicked on the above link and couldn't believe what I read -- I'm
starting a new thread. The Florida Museum must have posted this web
page as a practical joke ------ --Mark
