Hey Danya. If you do a Google search on these great little geckos, the few sites that do come up, is about all the info you'l l find. I myself find any in depth info on them quite scarce.
I had 2.2 Helmeteds for bout a year, but lost them to the heat wave we had back in June.
I came home to an apartment that was 90 degrees, and 2 were dead, and the other 2 went the following day. Surprised me that I didn't lose any Rhacs to that kind of heat.
Packed up the survivours and went to the folks place till we got AC.
Anyway, looks like a female for sure to me. Great little geckos that are hard to come by. I miss watching my guys hunt crickets.
