well they should be getting comfortable w/ there soroundings by now. do you have anything covering 3 sides of your aquarium? if not i would. have you offerd crickets yet? if not i would try often times movement helps on getting them to eat. if they are in a high traffic room try moving them to a room w/ less traffic.
if any of them have pooped i would take some to a vet to get it tested. if any more problems arise or there current status continues dont be afraid to post again or e-mail me.
