What's wrong with my convict?

[Lillyrosesmum]

Noticed a bubble on his back a few weeks ago. It's not discolored or hard. When we asked around about it they said to wait and see. Anyone ever seen or heard anything like it? Wish I had a better picture! Those guys are quick!

Thats Strange.. Is he eating well still? I couldn't find any info about it on Google. Hopefully someone on here sees your Thread and has dealt with this before.

He seems completely fine. Eating well and everything and I couldn't find anything either.
