gargoyles and cresteds have pretty much identical husbandry requirements. you may have to keep gargoyles separated when they are young as schlyne mentioned because they will bite off eachother's tails and possibly be more aggressive toward eachother. i have had no problems housing juvie cresteds together. i'm not sure how easy gargoyles are to breed but i imagine it would be similar to cresteds. if you want to see some reeeeeally nice gargoyle morphs go here: http://classifieds.repashy.com/showcat.php?cat=6.
