Who is picking on my Yellow Clown Goby?

I have...
Firefish Goby
2 False Percula Clowns
Sixline Wrasse
Skunk Cleaner Shrimp
Sally Lightfoot Crab
Various Hermits and Snails
We have had the Goby for a week and it never missed a meal until tonight. I would sit on a rock out in the open until tonight. Tonight, it has holed itself up in a hole in a rock and did not come out for dinner.
Should I worry? Any ideas on who the likely suspect would be?
Thanks, John

I would keep an eye on the six line or the sally lightfoot. Six lines can be very aggressive to newly introduced fish that are passive. Spend some time watching the tank and see if you notice the sixline hanging around the goby's burrow or chasing it if it comes out.

I will. I have been watching the Wrasse and it pretty much keeps to itself. The only aggressive behavior I have seen with it was when it picked up a snail off the top of my rock work and tossed it off.
The Sally Lightfoot stays in the rock work and rarely comes out. You see her (and she is a "her" per the LFS) every day, but in the lower parts of the rockwork.
Maybe this is happening at night!

Smaller than the Goby. The biggest one is running around in a Nassarius snail shell. John
EDIT: On further review, the largest hermit crab is the same size as the Goby if you count the shell size.

Update: As of 10 pm MST, the Yellow Clown Goby is nowhere to be found. Now I have a lot of rock so this little guy could be anywhere, but it was in a pretty safe place and moved for some reason.

The reason might be my red brittle star. When the tank lights went out, he left his hole and was nearing the rock that the Goby was holed up in. I did not see him get in there, nor could he given the size of the hole, but he could have gotten the Goby if the Goby was weak. I noticed that the brittle star moved back into his rock so you never know.
Anyway, I will post again tomorrow. I expect that if the Goby is not out for dinner, it has passed on.

This AM the Goby was sitting on top of the rock that the brittle star hides out in. It looked pretty normal to my very untrained eye. Of course nobody was out yet for the day as the lights were still off.
I will observe this evening and at feeding time.

I added a sixline and it killed my clown goby, started with ripping off some scales and two days later it was gone, I couldn't catch it in that tank.

I am sorry to hear that. I am now suspecting that the Goby is hiding from the wrasse. The wrasse is all over the tank and spends a lot of time hunting for something.
I saw the Goby briefly tonight at feeding time. It is hiding, that is for sure. It only comes out when the other fish (exept the clowns) go to bed.
Any suggestions?
