HELP, fish missing and coral dying...

Interceptor will kill all your hermits, shrimps, pods. Best would be to figure out the rock the crab is in, take it out and soak that rock in interceptor (dog heartworm medication).

whoah, wow....
much appreciated but i think I'll see if I can trap him as Terry suggested before i drop the i bomb or anything...
I would rather just feed my tank extra so the renegade crab doesn't feel the need to eat coral for lack of detrius...

Okay.
Today I got home and found my blackray shrimp goby had a huge gash up it's side, this is about 3 weeks after I introduced him and his pistol weilding partner (the pistol shrimp has not been seen since his introduction to my reef, though I think this explains why) and while a hider he was eating voraciously and getting along very well waiting for his shrimp to show up and build him a house.
I knew right away that whoever was responsible for this injury was also resposible for killing the aforementioned leather coral and maybe even the clown goby, though I'm still pinning that on my clownfish.
I looked to the trap I had set up, the much debated pop bottle funnel kind and saw my electric blue hermit as dead as could be with the remnants of one last satisfying meal of squid strewn around him.

Needless to say, my frustration over this ongoing matter had reached a tipping point.

Sitting down on my couch and peering into the tank in dismay and feeling somewhat desolate, I saw movement.
I jumped and looked closer and saw a pincer with stripes like a coral banded shrimp dissapear into a piece of live rock. I plunged in after it as fast as I could get my gloves on and pulled the rock out, going over it again and again not finding my intruder I gave up and looked once more to the tank. It was only a minute before I saw another body under an adjoining piece of live rock, I acted without delay this time and procured a small grey crab with beady red eyes.
I celebrated and put the pieces of live rock back into their places and marvelled at how easy that had been, if stressfull on my fish. It was then that I saw a familiar banded pincer stretching out from a crevice on the recently returned rock.....needless to say I got him the second time around and what a mean looking little crab he is.
Looking at them it's hard to believe that these two little critters caused so much carnage and cost.

Thanks for the help and suggestions, I really hope this is the end of this matter.
