In my experience, ricordea moved around/put into a new environment stop reproduction for quite some time. May take months, I had a ricordea that didn't start plitting for over a year. However, the best thing to do is let it be, and it will start. And once it starts....watch out! That same ric that didn't split for a year made about 8-10 babies via pedal laceration in a matter of weeks.
