I've been wanting a Crested Gecko for the longest time. I have lots of smaller and medium sized snakes but no lizards. I don't have room for most species so I think a crested gecko would be perfect. I just have a couple of questions. I've read on alot of care sheets and most say that room temp is fine. I keep my reptile room at a constant controlled 80 degrees. Im basically full compacity in my reptile room so the crested gecko is going in the living room. The temp in my living room ranges from about 72 at daytime and sometimes drops as low as 66 at night. Im wondering if 66 is to cool? Also planning on keeping him/her in an exo-terra 12"x12"x18". Would that be ok for one crested for its whole life? Thanks
