iv had my frogs for two months and still sit there and think 'oh god i cant see any movement, is he dead?' i usually mist in their generaly direction and his heart beat will increase and i know hes ok. he tends to sit in the corner and not do very much where as my other frog wakes up wen i open the terrarium. i think they just have different personalities. ull probably find that the frog has moved in the night and has just gone back to the same spot during the day. like don said tho i guess it depends wot frog u have. i have whites and am gettin used to havin a lazy frog.
