I purchased 3 adult frogs from a very good supplier. A lecomelus, glactonotus and auratus costa rican green. the lecomelus and costa rican have been seen or found very easily over the past 5 days. The auratus was out the first day but has not been seen since. I have looked under all leaves, coco pots, large plant and behind back wall. the vivarium substrate is a gravel like material, screen, coco stuff (fine) and topped with some moss. There is a large piece of wood. Should I be concerned? where could he hide that I haven't looked,(could he be under moss)? should I remove all objects to find him. ETC

Secondly, after day 14 how many fruit flys per day should a culture produce. they are melanger(sp) temp is about 77 humitity about 60. I seem to get about 25 per day. Is that normal and if not what could I do to help.
Thanks for any input.
