i took a 3 week vacation and left my geckos at my girlfriend's house so that she would take care of them and my smallest gecko, who is less than 2 months old at the moment had a bad shed because of low humidity. there is unshed skin constricting the tip of his tail. will the tip fall off? or what ca i do for the skin to fall off? is a high humidity hide enough? or should i treat the tail with olive oil as well?
