We had these guys for quite some time and they of course were houses separtely, they did extremely well with no spot light and a fogger on at all times, they enjoyed being sprayed down several times a day but in the Southern California average home do not need heat, the male looks extremely stressed in that picture and in all the time we had him, never got that upset. He also was very comfortable in his surroundings and hung out in the same place most of the time as most Deremensis don't move around that much. He may be stressed and trying to get cooler as if he was in a cooler environment with higher humidity, he may tend to stay in one area and not show stressed colors. Just thought I would let you know as we have had them for quite some time and want to make sure that you knew where they were coming from and how they were before you got them. Let us know if you have any questions.
