Ok, I'm hoping someone can help me with my BEL.

About 3 weeks back I cleaned out everything in her terrarium.
I used reptibark because it just looks nicer for her display.

I can't be certain but shortly after doing that I noticed some red'ish type areas along parts of her body. And it's all only on the bottom and sides (no red areas on her top-side). The photos I'm including were taken just after she ate (frozen-thawed).

Has anyone ever noticed this with their animals?
Is this caused by new substrate? As in did the substrate sort of dye her body as the new substrate started getting moisture?

I don't think it has anything to do with her food. Doesn't really appear to be blood.

Her behaviour and demeanor hasn't changed.....



Any ideas?
