Hello!
I'm from Norway, so you have to excuse my somewhat bad english. 
I have a few questions about the housing of chinese firebellies:
-Is sand the best and most natural substrate for these newts? Can the sand be a little rough, or does it have to be very fine?
-I've read that they don't need as much land area as other newts and salamanders do. Is this true?
-Can I give them earthworms that I find outside, or do I have to buy "can worms"?
I hope someone can answer these questions, and please forgive me if some of them are a bit strange.
