Odd cleaner shrimp death or molting

[adova]

My daughter found a our cleaner shrimp dead and being fed upon by a blood shrimp. My initial response was that what she thought was a dead shrimp was molt. But I didn't think there would be anything for the blood shrimp to play with / eat.

The cleaner was out and strong earlier that day and the 3 blood and 1 cleaner have been tank mates for about a month.

Is there any chance that this is just molt? I had heard that bloods can be territorial. Not much else in the tank - 2 clowns and 2 grammas and a snail CUC in a 180g.

Is the thing in question transparent?
If not, it's probably a dead cleaner. In that large of a tank, I doubt the shrimp fought, so the cleaner may have died of something else. Was the cleaner full-sized?

The shrimp was pretty hard to see as it was back in a cave area. He was full-sized. I will keep checking params just in case...

Hmm - well now it looks like I have lost a Tuxedo Urchin. Not a good sign. Chemistry is in line, so I will have to look for other factors. Any ideas outside of chemistry?
