I wish they could be temp influenced like a gecko.
But I doubt adult female gilas would be quite priceless on the market if it were so. Actually imo they are born about 2/1 m/f scewed on average, or maybe I'm just unlucky. In the six years or so I've been studying gilas and beadeds all twenty or so I've raised have ended up 60% male, both in gilas and beadeds......
