She had it when I got her, though not as bad.

She was in a 30g tank with a screen lid (bad) and she didn't like it. So, she rubbed her nose on the lid. Ouch. I covered the inside of the lid with fleece, except for about 4" on one side for ventilation. She found the 4" with her nose. Ouch.

I moved her to a honkin' big sterilite tub. She found a sharp edge with her nose. Ouch.

I bought her an expensive 4' boaphile cage and she found a seam with her nose. Ouch.

Now.. I THINK she's settling into her 4' palace and has stopped rubbing. I haven't heard her bonking her poor little nose anymore.
