Is my one year old garter not growing fast enough? (pics)

Pinkies and worms provide enough nutrition/variation. Plenty of people feed a worm or pinkie-based diet with no problems (though they do love fish). Also, if you're feeding prey that has bones like silversides or pinkies you don't need to worry about a calcium supplement.
I like to feed younger ones smallish meals two or three times a week as opposed to a single weekly feeding. My really old one seems to keep his weight up better when his weekly food is split up over a couple days as well. My year old female probably eats 1.5 pinkies and a worm or silverside each week, but not all at once.

okay cool! That was exactly what I was looking for I usually do try and split feedings up and before I would give 1/4 of a pinky and then a few days later I would give her an earth worm. I'll keep up with the twice a week feedings but I'm going to start increasing the amount of food I give her. I got some Tilapia today so hopefully she'll eat it.

when their diet is varied,problem is for this snake the diet was not varied nor was it fed enough,

I'm sorry but I think my snake's diet is varied enough. She eats both pinkies and worms regularly. Fish is not required for her to be healthy although I just got some Tilapia and will be offering it to her. I haven't been feeding her as much as I maybe should but she is not skinny and as a young baby I was warned not to feed her too much because their digestive system isn't strong at that age.

Snakes do not require multivitamins when their diets include whole bodied animals such as mice and whole fish.
