Who kill my Four line wrasse

[optimusyue]

Hi guys

bought a four line wrasse on Sunday and it was swimming happily with the rest of the tankmate. But come home tonight and found it dead at the bottom of the tank. There is what seems to be a dark patchmark near the tail. Any idea what could have happened. Could it be attacked?

Thanks.

MY four line died too...

It just disappeared one day and i cant find it till about a weeklater.

Can only regconise it thru a roughly fish skull shaped debris at the bottom of the tank!!!

I think that crab i saw on my living rock killed it.... 1" crab to a 2" fish? Unlikely u might say, but there is no other better reason i can think of....
