I see lots of people feed silversides but my garters wont eat them(2 infernalis 1 eastern) I have tried putting other food in (worms,pinks) but they wont even look at it. I bought a 5lb frozen block at a pet store,sealed,look fresh,i dont get it they will eat guppies and trout fillet,heart and liver,sometimes before the dish hits the bottom of the cage.
