I had something weird happen when I was handling Striker, my big male BP. A weird whitish thing popped out of his vent. I wiped it off with a tissue, and it came off easily. It was kind of a beige color, actually. I read on a different site about "sperm plugs" and was wondering if anyone has ever seen one, to describe it, and see if this resembled that.
I do know that he is a male.
