They are nocturnal......from what i have gathered about them as a species, they are from the desert (am i right there ?) in the desert, there is sun (i think) so in theory, some sunlight cannot be bad for them, obviously not full sun, but some is surely better than none ...
as with beardies as well apparently, taking them in the sun occasionally will bring out their colours (although that isn't really important)
