Camel shrimp murdering hermit crabs???

I used to have 5 hermit crabs and am now down to 1 today, was 2 this morning, I keep find little crab bodies hanging around the tank.
Well today, I had 2 crabs, both walking around eating....and all of a sudden tonight, I see the shrimp holding him and having a feast.......are they known to kill hermit crabs??

what your seeing is more likely the molt of a hermit.

never thought of that :)
makes sense, since I found the MIA crab this morning, just looked like a real crab body the shrimp was eating

Those Camel Shrimp are bad news though. I had one a year ago that ate a Starfish, leg by leg. I have heard they can nip at corals, too.

Nothing good happens fast in an Aquarium

I was actually thinking about bringing him back once I make the transfer and get a blood shrimp instead

ALthough kept numerous s/w hermits for many decades (still have 5 hermits at this time from near by ocean), I never had the pleasure of witnessing their molting. I did witness them switching shells or other crustaceans molting
I really cant say if camel shrimp can actually penetrate new soft shell of hermit. If anything, Ive witnessed hermits take each other apart.

I guess this is why I thought it was a crab body, looked just like the crab itself, withouth the shell, claws and all. all I know is the shrimp was really enjoying it...

Next question, if I do keep the shrimp, would a blood shrimp be compatible ?

I have also heard they can nip at corals, but he was sold to be as a peppermint shrimp....found out after research that it is actually a camel shrimp, the bulging blue eyes gave it away.....

I dont know about camels being predatory like other (mantis ,etc) shrimps are but mere opportunist as all other animals are as far as I know.

Did experienced camels affecting general health of some softies but when kept well fed, they seemed to leaved the corals alone.

I heard of such errors b/n camels and peppermint in few forums but I wonder how as they do have totally different body shapes. Never have heard such locally!

I strongly doubt it was camel who went on rampage rather fighting/killing among themselves over shells. iIliterally saw one pull other out of its shell to claim his prize (new shell).
Dont know the size of tank nor what kind of hermits, so I cant say for sure. I would always have extra shells laying around on the substrate when keeping hermits so they can find new home without fighting/killing each other.

Among 5 I have, this is what's left of few more I caught past summer, they do go at each other, especially during feeding time. I could hear them bumpimg onto glass while running and chasing each others. I did notice recently one is actually turning greenish colorbut it is not the most dominant one.
I ve seen my wild caught shrimp/prawn dine on dead/torned apart hermit. Plus I also have tiny to mid sized local crabs which doesnt turned down free meals, which btw were born in the tank last year.
What a show/sight as many female crabs do the dance to shake the eggs off.

Hope things settled down for you soon.
