[gecko]Strange behavior of Gold Dust Day gecko?

[Karl Fritz]

Hi all again. I was also wondering if anyone could interpret the strange behavior of my Gold dust Day gecko? She has been digging and burrowing her head in the Orchid Bark. I've never seen any of my day geckos do something like this.      Here is some background. I traded for a captive bred male about two months ago. About one month ago I also bought the Wild Caught female in question. She had been in captivity previously for at least 6 months. The previous owner had her with another male but said she wouldn't breed. Since I already had a male, I just bought the female hoping she will get along better with my male. He showed some signs of interest, bobbing his head and approaching her, but I've only seen her reject him so far. There are no bite marks on either of them.      The tank set up is as follows: Tank is 12" wide by 18" deep and 18" high with pebbles at the bottom, followed by potting soil and topped of with a layer (1") of Orchid bark. There are live plants in the tank along with horizontal and vertical bamboo pieces for them to climb on and to get closer to the lights when they like. I put the male in this new tank for him shortly after the female so he wouldn't have a chance to set up territory first. There are two lights (1 fluorescent and 1 incandescent). The temperatures range from 75 at night to 85 in the day. If they want to be warmer than this they can sit on their bamboo under the lights. The tank is misted for drinking and humidity at least three times a day.      So has anybody ever seen day geckos do something like this before? Any thoughts?   Thanks,   Karl
