My guy got real dull and pale looking and hid for 3-4 days,I came home tonight expecting and hoping for a shed,to find nothing,look in my tank 10 mins later and he's shedding and it all came off in one piece,so pround of my boy....feeding him round midnight...he's probably shedding. Don't stress it man.
my only advice is keep the tank constantly moist and high in humidity,that's what I did.. Kept temps around 86-90 and humidity atleast 70 as often as I can
