I have had an Apalachicola King for about 3.5 years. He typically eats every 1.5 weeks. When he is getting ready to shed he will not eat and sometimes has gone 3 weeks total between meals until he sheds. He has currently gone 6 weeks and has appeared to be getting ready to shed. His skin is flaking off but has not come off in any large degree. He is drinking well but just not eating. Any thoughts??
