Your photos still are not clear enough to be 100%, but they do sort of look like waxy monkies. I have never care for them but they have always interested me. I know the adults like hot drier conditions but since yours are young, you should add live potted plants to the enclosure to increase humidity. Also keep that paper towel a little moist. From my previous frog experence, when it comes to feeding new frogs, sit and watch them eat. Dont just throw bugs in and hope they eat them. Crickets and other insects will bite and try to eat any lathargic, slow or sick animals.
