I was weighing my pastel tonight and I noticed these red spots on her belly.

She's being housed in 1/2 of an AP T8 with paper towels as substrate, and thermostat regulated heat tape. The cool side/air temps range from 80-85 F and the hot side basking temp ranges from 90-93 F. Humidity stays around 60% with minimal misting (a few times a week at most)

Here is a picture (I can take more if needed, just let me know)



Can anyone tell my what's going on?

Thanks in advance
