my easterns love worms. my eastern black necks will not touch it. all of the garter species i've worked with seem to like fish. these days i just get a pack of frozen sally silversides from petco and cut it into little pieces for my baby eastern black necks and eastern flame garters. haven't lost a baby yet. since the fish is frozen, very unlikely chance they'll catch parasites. i slowly transition them to chopped pinks that i mix in with the chopped fish and eventually just to small juvenile rodents to make it more simple for myself. no more worms. remembered when i bought a thousands earthworms at once and if they get too warm they drop dead and the stench of the dead worms was horrible
