Dont rush things. It took mine (not the same species as yours however) about 4 days before they finally ate something. I know how it feels either your doing something wrong or something is wrong with the geckos but be patient. It will pay off in the end. Its stress going through the air tumbling around in a pitch black box and not knowing were your going. Get them in their enclosure, offer them some food after the first day, and mist them,etc but other then that leave them be.

Good Luck.
