While variety is best, I like to know more about individual food items (in case some types of foods wind up unavailable for lengths of time). Has anyone maintained garter snakes for long periods exclusively on worms? If so, they remain health and vigorous, grow normally, etc, or did they develop issues? If they did develop any signs of deficiency, what were they deficient in?
(I know that worms are high in protein, low in fat, and have a good calcium/phosphorus ratio, but I don't know what they may be lacking, and that's the info I am after).
