Mystery of the morning
 

So as I'm observing my 90g reef in the dark this morning I noticed that a few things got rearranged overnight.... Mainly a couple of zoas that were not affixed to anything. No big deal this happens from time to time... Then I notice that a chunk of rubble about 2x2 is moved... Something is missing... So after looking closer I see that one of my zoa colonys are gone!! So on come the actinics and I'm looking for where they ended up... This is where it gets weird... I found them somehow pulled into a little cave area in the rockwork.. So basically the rubble chunk was pushed out onto sandbed... And the zoas that were next to it pulled in and under the rock..

A- I'm not sure I can pull them out without dismantling the left side of the rocks
B- I'm scared there might be a monster in there :s

my immediate thoughts are do I have something nasty lurking in there trying to lure me with my zoas? Does anybody have any thoughts.....

Sounds like the work of a.....CRAB ! (or possibly a shrimp (pistol or bulldozer).

I had a baseball sized colony of dendros move six inches across the sandbed last night...

Could be a worm....

Reading this link may make you think twice about sticking your hand in the tank..... I am glad I yanked the one I had at only a foot long!

I still say if there is alien life on this plant it's in the oceans... There is just too many weird and freakie creatures fish and corals.... Maybe you have a Kazoo crab in there!!! Ya know the guy from the Flintstones with super strength!! I wouldn't retreive them, he could get peaved and leave the tank tonight looking for you lol

Thanks, now I have an uncontrollable urge to go call someone "dumb-dumb"

yup
 

I have heard of bigger worms doing this... but crabs might too.

If it is indeed just a crab that feels the need to move stuff around I MAY be ok with it..... If it's a pistol shrimp would I not see a burrow of sorts?

OMG!!!! Thanks for that JonT.... That is indeed a monster!! How did you find and catch yours?? Better not be what I got going on or.... YOU may have to come catch it for me :o

Could this be a mantis??? Regardless of what it is I know for certain it is not the work of either my chromis or clowns... Should I set up a bottle trap in the area this evening? I just want to know what it is.... I'm creeped out!!
