Brown jelly disease

[corey904]

I’ve noticed one of my torches hasn’t been looking as happy the last few days the other euphulia in the tank are doing great
Today after watching it for a while I saw skeleton on the top right
Can anyone identify my problem by photo?

Need a better photo preferably with white lights on. Could be BJD on that top right part.. or maybe the hammer hit with a stinger? How long have you had the torch in question?
