Fire shrimp dead

[Ga1981]

Hello there , I "had " this healthy fire shrimp , at feeding time he did not show up tonight, I found him now without head.... I know sometime cleaner and fire shrimp fight, but cutting the head off is extreme. I noticed 2 weeks ago one of the cleaner was dead, they been all togheter for a couple of months now. But anyways last Sunday I saw my yellow tang picking hard on the cleaner shrimp....right now the 6 line is picking on what used to be a fire shrimp.
Anyone experienced this before, could be the 2 shrimp fighting?
My livestock in a 70g is
2 clown
2 firefish
6 line wrasse
Yellow tang
Hippo tang
Blue and scarlet hermit
Snails
Tuxedo urchin
Thank you

doubtful he's dead most likely a molt keep a eye out he'll show back up in a day or so
there molts look so realistic you would think it was the shrimp itself
