I do not have the time to bath him every day, unfortunately. I wish I had more time in general. I recently removed most of the excess shedded spikes, but there were a few I couldn't get off. Maybe if I wet them long enough, they'll slide off.
Back to the skin, I do not believe it is blood, because the scales themselves have changed in color and the skin has "paused" shedding up to that shift in color.
