Possible abuser of melanarus wrasse

[LSUJosh]

So I got a melanarus on Saturday. After drip acclimation it dove straight under the sand as I expected. It stayed there until the following morning. Sunday it was out all day swimming around, eating and I never saw anything bother it. Now I did not see the wrasse again until Last night. Last night it popped out of the sand about 8 hours after the lights came on, it was missing a side fin and it looked like its tail had been nipped at, it died within the hour. Its tankmates include: yellow tang, powder brown tang, 2 b/w o. clowns, 5 blue/green chromis, 2 engineer gobies, and 2 canary wrasse. Does anyone have any clue who could have been the culprit? I would really like to get a new melanarus wrasse but I would like to know who I should watch more closely next time.

What invertebrates are in the tank?

Corals, rbta, snails a couple of hermits and an emerald crab, a cleaner shrimp and a few peppermint shrimp also.

If I were to guess, I would say the emerald crab if it is largish. I did not see any fish on the list that stand out.

Maybe so, I would not call it big, maybe an inch or so but that was my best guess as well.

I know they can take fish. I certainly do not trust them.
