What ate my peppermint shrimp?

[gsar]

I'm trying to figure out what might have eaten 3 out the 4 peppermint shrimp i put in my 75 gallon.

A while back I got them to clean out the aiptasia in my sump and they did a good job. After they finished I moved them into the display and about a week later three went missing. I have the following fish in there.

Pair of tomato clowns
One coral beauty
One chromis
One lawnmower blenny

No other crabs (except little hermits) and I've never heard the sound of a mantis. Actually had a cleaner shrimp in there for 6 months without any issues before i moved it to different tank.

Anybody ever have a problem with tomato clowns dining on peppermints? I haven't heard any of those fish being a problem.

they are probably hiding-only come out at night

[Myka]

Ya, prob hiding. How big is your tank?

[JonT]

75 gallon tank, yeah, I would bet they are hiding. Did they molt recently? If so, they are for sure hiding.

How is your salinity? Rapid changes to that can cause sudden death to inverts.

Salinity should be stable. It's been running with an auto top-off for quite some time but it is possible that my recent water change may have changed it slightly.

I'll check it out in the middle of the night just to make sure but they didn't seem too shy before they went missing. There's no sign of them when I feed the fish either.

I've just never heard of these fish going after them.

There is also a possibility they died from not being acclimated properly. I personally had issues with shrimp in the past when I didn't acclimate them properly. They lasted only a week or two.

Ever since I started to drip acclimate survival rate has increased tremendously.

Just my opinion,
