gecko info needed.

im a little confused on the habits of the gecko. since they are nocternal do they like to sleep at about 85F or should it be 85F when the are awake at night. my gecko has been sleeping all day and i was wondering if it was because it was to hot or he is just tired. he dont like to come out of his cave at all. he spent all his time in there since about 10:00 am this morning and he is still in there and it is currently about 2:00 am i seen him come out once to eat. is it maybe because he is dehydrated. so what are should the temp be at night when he is awake. i thought that if it was to hot he would move to the other side of the tank where it would be cooler cuz there is no heat lamp over there. could he be hiding becasue he is in a new environment cuz i just bought him?
