So i got a new tegu and if i need to let him settle in and get used to his surroundings without messing with him, so i dont stress him out, how should i go about feeding him in a food bin? i have actually had him for a couple days and the first day i fed him in the bin and he ate a lot then basked all day then the next day i put him in and he ate a couple crickets then wanted to get out then he basked for a while and all day today he stayed under his substrate and hasnt come out so im assuming he is frightened.. but i dont want to keep stressing him out what do i doooo?
