[Snaky]

It's more or less the same as for handling the adults, but smaller. So: small pieces of fish, earthworms, pieces of pinkies.... Sometime's you need to 'trick' them into eating, you can do this by cutting the earthworm into pieces (so they still move) or offering life fish in shallow water.

For the indonesian garter: I've always heard that they need to be kept warm. But I don't own them and have never looked it up, so hopefully someone else will answer that for you.
