I "chilled" my Motoros as an experiment awhile ago and they just did not seem to have much of an appetite and their colors dulled. They are fine now with no ill effects.
Find a temperature that you can comfortably attain and maintain for them. Sorry, sometimes rays are just not that compatable with other fish.
