Hi there!

I have a 1.5 year old rainbow boa with an odd scale on his back. The scale has some white coloration and is slightly raised to the touch, and it's about 1/3 of the way down his body (pictures included). I'm not sure if it's problematic or if its in the process of healing or something similar - maybe it got caught on something?

In terms of husbandry:
- substrate: forest floor & coconut fiber mix
- humidity: ambient anywhere from 50-80, with a humid hide always provided
- temperature: ambient 78(ish) degrees fahrenheit, hot spot provided by UTH but with so much substrate I don't know if much heat is getting through. I use an infrared bulb thats placed in the middle of the tank so the middle of the tank is the warmest part

What is it and should I be concerned?
