they are very tempermental when shreading ther skin, as they like to be left alone during the process. they will be off food and will soak at lot to ease the disscomfort, It is important to keep the waater dish clean during descremation. U could aso put a box in his viv filled with moist moss this will also aid his discomomfort. Although they do like to be left alone they is a possibilty of mites which u should be able to feel whilst doing this you could listen to its breatheing if you hear anything unusual then likely hood is RI which will need trating asap. If u are still unsure as u have only had him / her for a week take it back to where puchace took place and explain your worrys any good reptile shop is always willing to help, Although this could cus settling in proccess to take longer. Good luck!!!!
