Be careful w/an absolute statement such as the one you made in your post.."never" is a very strong word. "Tropical" does not equate to static temps. World-wide there are seasonal changes in which the inhabitants have evolved.

Certainly shortened daylight hours need to be taken into account and a coinciding drop in temps. combines to become a natural trigger. While the night time lows would not have to be as extreme as NA Colubrid cycling nor as long of a brumation period, it still needs to be done.

A NTL in the mid 60s with a coinciding warm-up to the low 80s for a few hours a day should do the trick..also good to ward off potential any potential UR issuses. An increase in misting is always a good trigger for tropical Colubrids. Unlike our resident rat snakes, the triggers need not be as extreme or prolonged to get things moving in the right direction.
