In my experience the only difference as far as breeding the gargoyles is the compatibility of the males with females and females with females.
It requires a bit more care and oversight when introducing geckos together. Most of the time they get along, but occasionally problems arise, especially between multiple females.
After I put gargoyles together, I monitor their weight and condition very carefully for the duration that they are together. Any signs of dramatic weight loss, or scarring is a big red flag.
