I recently aquired a male leopard gecko who is just huge...he reminds me of something I have seen in Petco (I hate that place, but only spot to get yesterday's news) that they have labled as Jumbo Leopard Geckos. Does anyone have any information on these, he's also been running around and vibrating his tail at my female in a cage that he can see...I'm assuming that's some sort of aggressive display to show that he's the boss?
