I guess they stay pretty small, 4-5 inches max. they eat meal worms, crickets, and some say they feed them supers. I just want to know what is best for them, and make that decision on getting them or not. I guess they love to dig, and prefer a dirt/sandy substrate. I don't want to take them on if I cannot give them what they truely need. Anyone ever deal with these guys? Online care sheets are few and far between with, in my opinion, too generalized information.
