Hi There,
First thing to say is don't worry if they go a little quite they can be grumpy buggers and dont like change so just bear that in mind. Let the litte one settle the less contact and quite the better for the first few days (handling can cause distress even if it is very hard they are just so darn cute!)
One thing you may struggle with is a temp, we just couldn't manage it when Ralph was little so he was in a viv to start off with but not ideal for very long. Make sure you have a ceramic bulb on a thermostat throughout the night, we then switch it over in the morning to a sun bulb that's on top of his UV strip.
The best advice I could give you, is all torts are different what works for one may not for another and owners can be precious about their methods
For example some feed pellets, some feed fresh only.... all are correct for their torts so do what you feel is best based on what you know.
Anyway it's a lot to digest but we are here if you need us. Enjoy your new addition
