un-seen predator?

ok although my tank is a nano i do not fell this is a "nano question" if you feel it is feel free to move this (just drop me a line to where you put it)

i have a 10 gallon

in it i have...
7 Hermite crabs (3 red legged and 4 blue legged) and 5 Nassarius Snails

i had 2 peppermint shrimp (missing a couple of weeks now)
and today i can not find my happy little Ocellaris Clownfish , he was fine yesterday, waggity tail and all

strangely i have not seen any sign of the 3-4 bristle worms that came on my lr in over a week either (they used to come out at feeding time) this may not be a bad thing.

my params are fine (ammonia, 'trite and 'trate are all 0)

admittedly the clown could have jumped out as i have an open top and a inch or so of space between the top of the water and the light, but i can find not mummified body on the floor or behind the stand. if he died i am sure that the crabs and snails would have made short work of the body.

but the fact that the shrimp and the worms are also missing has we worried.

could i have an unseen hitchhiking predator on the loose? none of my lr pieces are very big, and none have any large holes so i do not know where something would hid. how can i know for sure?

what do you think?

this tank shot is a couple of weeks old...


TIA

The missing clown has me worried but not the shrimp as they hide alot. I have three peppermint shrimp and never see them except their molts so I know they are there. I would maybe do a few nite time inspections with a red cover over the flashlight to see what is in the tank.

Any strange clicks coming from your tank? Is your live rock from the Atlantic or Pacific? Seems like mantis shrimp are way more likely to come in on Atlantic/Caribbean rock.

Could be a small crab try a glass tilted with food in the bottom and lay in wait it may take a couple times to do it, it could also be hidden well with in the LR I had 2-3 of them and it was like an infestation there fore I changed my LR out so that I got rid of them , it is possible that the clown just died and the clean up crew did what they do drug it to a cove and had a feast ...

The thing is if they place all the rock into a common bin it is possible to come from just about any where , even from hitchhiking in or corals in your tank ...it would amaze you how they tend to "burry" themselfs

Hmmm...How old is this tank?

From the pic you posted it looks like you have a lot of diatoms in your tank which tells me that it is still a new tank??? Are you sure that your water params are all in check? I would test them again just to make sure.

You could try soaking your rock in a hyposalinity (very salty) tank to see what crawls out.

HypOsalinity is low salt water
HypERsalinity is high salt water . I agree it looks like it is a fairly new system
