So I'm doing my routine maintenance on my reptile friends tonight and I noticed my spider had a rather large lump on the bottom of his jaw. This just popped up recently within the past week. It doesn't seem to bother him, he's acting normal. The only thing is, he hasn't eaten the past two feedings, now he has been courting the females and this is their "off feed" time, so that may be the cause. I included pictures, let me know what you think. Sorry for the poor quality, he wouldn't sit still.
