My Nicaraguan just went through this. He hid for 4-5 days before he got cloudy. He cleared up several days later and 3 more days went by and there was no shed to be found. I offered him a meal last night and he took it without hesitation.

I raise his hide to check on him today and there he is sleeping beside his old skin in his hot hide. The whole process took longer than normal and it seems to vary from shed to shed.
