My Red sided garter snake ever since I found him will only eat minows. (which apparently are bad for him)
I've tried scenting frozen silversides and other fish and worms(earthworms and nightcrawlers) every time I feed him minnows. I put them in the same dish and I've cut up the worms to fish-size(and some other tactics). How can I get him to eat something else?(no pinkies)

My parents only let me keep a garter (instead of corn snake etc.) because they didnt have to eat mice. Plus I dont have any localy owned pet stores near me and petsmarts pinkies are to expensive anyway.
