I have a Coral Glow and it amazes me how many new spots appear when they shed, in your pics I would agree with the others those are just freckles. Does he look like he may shed soon that may be why he's soaking? Also just to state the obvious but have you checked his hot side temps? I've heard of them soaking when it's too hot. I figure with 11 snakes in your signature temps would not be an issue but I find myself realizing every so often that I haven't spot checked temps in a while and will grab the temp unto check them. One of the dangers of Herpstat's I suppose, they're so darn good!
Nice looking Banana BTW and nice selection of animals.
