i've had two leopard geckos for about a few weeks now and i have 2 hides and an average sized tank. both geckos are about 4 inches but they keep sharing a hide. one of my geckos were standing (sorta) on the other one in the hide today and yesterday, too. yesterday, the one thats been standing on top of my other leopard gecko was on them again in the hide and he was trying to get up a little bit but, they couldnt. i dont know what to do because i cant buy another vivarium. ): (sorry for the poor wording)
