I purchased two juvenile checkered garter snakes on Thursday and I'm not sure when/what I should try to feed them. I bought 4 frozen pinkies, I have 20-30 feeder guppies and a few earthworms! The one snake is very skittish whenever I approach the tank, while the other one remains hidden in the bedding almost all the time. Should I take them one at a time and place them in another critter cage with food to see if they will eat it? Any help or advice would be awesome!

Thanks!
