Two More Fish Missing

[kiharaconn]

Several months ago I lost two fish, a firefish and a purple firefish. The purple firefish disappeared first. I saw him swim into "his" rock and never saw him again. Then about a week later I saw my other firefish swim into the same rock and never saw him again. I baited the tank and got up all hrs of the night looking for something, anything but found nothing. I waited a few months before adding anything other than corals but when I added a foxface a couple of wks after he was in there I noticed a chunk out of his side. But it is healing. I purchased another firefish and he was in there about two weeks then poof he was gone. Now one of my clown fish that I have had over a yr and a half is now missing. So this past weekend I took out all the rocks and cleaned really well. I was hoping that while the rocks were out I would find something in there that could be eating a whole fish without leaving a trace but never saw anything. There was only one rock that I did not take out because it had a feather duster attached to it. I keep thinking that I must have gotten a crab in on some lr but my tank has been up almost 2 yrs and I haven't seen one. Does anyone have any ideas on what I should do or what it could be. At this point I would appreciate any advise. I am afraid I will lose everything in my tank before I figure out what is going on.
Thanks

Do you ever hear a clicking or snapping sound coming from your tank?

No I haven't heard anything. At first I thought it might be a mantis shrimp but then found out they make alot of noise. My tank is in the den so if it was that I should have heard it. I even turned off all the pumps and listened after it was quiet but still didn't hear anything. The other day I was in our lfs and the guy there told me that his tank has been up for 2 yrs and the other night he got up and saw a huge worm looking thing had ahold of his clam and was trying to pull it to a rock. He said that this was the first time he had ever seen this worm. My fear is that I'm going to lose everything in my tank. I don't know what else to try. If it is a crab will it move from rock to rock or will it stay in one area? If it would stay in one area I could try taking each rock out at different times and putting it into the fuge. But I really don't want to tear my tank apart again. And some of my corals are still not happy about the last time.
