The Madagascan species normally show you when they need potting by the
apical bud starting to swell. That said, when it doesn't happen at all, you
need to take a risk. 

Mold on a tuber is BAD! DO check if there is a soft spot below the mold and
if so, cut it out immediately or your whole tuber will turn into mush.
