Missing Peppermint Shrimps

Ok so Friday I bought 5 small peppermints to help with the Aptasia in my 65.

Well yesterday I never saw them and last night I looked with a red flashlight and no go. Look this morning and still do not see them anywhere. Looked in the overflow; in the sump and filtersock; nothing, like they just disappeared.
I do have a lot of hiding area as my rock is 90% Tonga rock so maybe they are good at hiding but I would thikn I would spot 1 out of 5!

2 Green Chromos

Any ideas as I do not think anything I have in the tank wold have ate them for dinner Friday night???

 

they can be very good at hiding for days.I used to have a couple,but hardly ever seen em.

 

they are still in there. Just hiding. I havnt seen the 2 that I bought for months, and just last night I noticed them both under a rock.

 

i put a couple in mine weeks ago i saw the first and second day havnt seen them since i have no idea if they are still alive but i notice missing aptasia so i assume they are

 

Ha I found all 5 of them in a holey porus rock that my Xenia is on and it is a rock that has/had several small aptasia on and it appears some of them are gone
