Trust me you can't ask too many questions. Just make sure to do all the research you can. For a hatchling i'd make sure the tank isn't too big and try to give him a hide on both the hot and cool side so that he can feel safe on whichever end he wants to be. Keep the water on his cool side unless youre having low humidity problems and then you can put it on the hot side to help with that a little bit. If you only have the one hide for right this second I'd probably keep it on the warmer side, but if he seems content where he's at i wouldn't mess with him too much. Letting him get good and settled in and feeling secure is really important for him right now. Just get a cheap tupperwear bowl to make him a second hide out of for now. Something that when he gets into it, he can feel the walls touching his body as if he were being hugged. It helps them feel safe. After thats all said and done with you should be able to try and feed him next weekend. My hatchling usually starts cruising his tank or stretching up to the top when hes getting hungry.
