I've noticed when I take my RES out of his tank and let him dry off completely I see this white spot. I'm afraid to scratch it or anything, so I'm not sure what it is. I know I have hard water, but I use a water conditioner, does that take out the hardness?

I also see this hole looking spot in his shell also. I don't want to poke around at it, but it just looks like a little hole, or maybe a scratch or something. He needs a shed, so maybe it's just on the older scute.

Also, the very edges of his shell (the yellowish tips) are very translucent, is that normal?
