What fish are safe to feed with?

[nekura]

Have you tried worms/night crawlers?

He's a Western Ribbon snake and from what I read they don't eat worms. I had put a worm in there with him as soon as I got him but no dice.


EDIT: Those mosquito fish look great. I'm in the far south, could you suggest any chains that would sell them?

EDIT2: Hah! You can order them off e-bay. I might end up doing this if I can't find anything else. Plus my parents are building a pond and are going to want some of these anyway.
