Illness/Sickness: What's going on with 2 of my notos!?!

[jbherpin]

I have 2 male, and 1 female Notos. The 1 male is having all sorts of trouble shedding, and now my vibrant female has a little left over shed on her hand and foot. What is the cause? Is there a specific ailment that causes this? How can it be remedied? My Notos are focal in my collection and a fav of mine. Any advice will be greatly appreciated!
