Is the BOTTOM of my A.Seemani's abdomen okay?

[xPaghetti]

The bottom of my A.Seemani's butt seems extremely bald. I've only had her for about 5 months, and she's been burrowed for three, and has recently resurfaced. I know the mirror patch is commonly bald, however is this normal looking for the bottom of their abdomens?

Completely normal. There doesn't need to be/aren't many urticating bristles on their undersides.

That is normal, nothing looks off there.

Yes....it's looks 100% normal!
