Hi, ya he looks fine now man you could give him something to eat. Sometimes they will stop eating and sometimes they don't know any better and they will just keep eating. with the cocofibre ya its a little more hard to find the poop but you should be able to find it if he went. If hes moved check the old hole, when they poop in there hole they move to make another. Or if hes very active just skim your hand across the substrate or what ever you use to pick up the poop, sometimes they will cover it by walking over it while exploring at night. When they get bigger this doesn't happen as much because they literally become lumps on a log and lose that baby energy. All in all he looks better and actually looks nice and healthy from the new pictures so ya I would let him eat.
