Bass will eat less in colder temps.....but having said that the temps depend on the bass and what theyre climatized to ; we have native smallies in the Ozarks that live in spring fed creeks that temps are never over 72 degrees (at the mouth of the springs they average in the 50s). I would say keep Largemouth at room temp (68-80) and theyll do fine.knifegill;4461418;4461418 said:Yeah, he's northern. I'll be gentle with him. Do you think being cold is going to stunt him? Or will he just grow at a steady pace? *doesn't know about bass*
