One of my male spiders have what appears to be a lumpy body. It wasn't like this when he hatch out and over the past few weeks it has gotten worse, He is an 07. All others have a nice smooth body, but one day I noticed a small hard lump on his side in the area of his high white coloration. It's not on his back or belly. He is eating well and is very active. but when you run your fingers down both side you can feel these lumps that seem to go away and then come back. Any sugestions?
