I got an azure dart frog about 2 weeks ago, he is somewhere between the froglett and juvenile stages. The guy I got him from told me he was 3 months old. Today I went to feed him and he just lays there, he moves if I poke him but not a whole lot, the humidity is 100%, Ive been feeding him flies and he is on sphagnum moss bedding with a false bottom tank, (2.5g). the temperature did drop a few degrees, from around 74F to around 68F, I have placed a black heat lamp on the tank, has anyone had this happen before? Please help
