Hello, I have two topics to discuss.

I was wondering if anyone could please take a look at my boa and give their thoughts on his belly? He is due for a shed but his belly isn't usually this pink. I am a little paranoid at this point because his scales are looking a bit beat up as well and someone mentioned that was an early sign of scale rot. It is very humid where I live, so much so that my veterinarian suggested I use Good Choice aspen bark shavings to dry out the tubs a bit to keep from being overly wet and thick in air quality. I am noticing beat up scales on a lot of my animals now and I am not sure if it's me looking way too hard to find something or if there is something up. So my topics are scale rot and pink belly, sorry to throw them together. The first picture is of my boa's belly. The second is of my ball python's (one of them) beat up scales.

P.S Can anyone please tell me if my boa is a BCI or BCC? He was sold to me as a BCI Columbian, but I know so little about boa subspecies. I'll post a third photo to give a better glimpse on him. Thank you entirely.
