Okay, so you are saying to keep it above or below the substrate? And I have one more question. ( i appologize for all the questions!!!)

I was looking at him yesterday night, and realized the there is the tiniest little blur spot on his left eye, and on his left nostril it looks like it is clogged with a tiny piece of shed. Do you think this is all it is, and will it come off next shed? THANKS !!!
