The temp flux in the tanks is never more than a couple of degrees as the heater and lights cycle on and off.
Or maybe I'm not understanding the conditions other people keep their shrimp under?
My tank is in the basement without any sun light. Even if I keep the same temperature in the winter, they breed much slower with the same controlled lighting. Maybe air pressure or something else give away the hint of winter, I don't know.
