I purchased this from thinking it was a waxy monkey tree frog but now im not so sure can anyone identify it? I dont think it is a waxy monkey cause he has tiger pattenrs on the side.
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.
Its definitely important that you find out if it is a waxy monkey tree frog or not since they have different habitat requirements (hotter and drier) than other frogs.
$30 is about the going rate (at least at the shows here in PA), and yes keeping it alone is perfectly fine. The only big thing would be if you want to add another frog later you would have to find one in the same size range as the one you already have.
