crab body found

[ReDDeviLs]

hi guys,just saw a crab's body under 1 of my liverock..

was happy at first...

wonder if my dottyback or sixline wrasse have attacked it because the shell was smashed leaving the both pincer untouch..

my dottyback and 6line wrasse have a mouth that big so its likely done by them.

but im alittle worry that it might be the work of mantis shrimp~and not my fishes..

what do you guys think?

Do you hear a few sharp clicking sound when your lights goes off ?

another bigger and more dominant crab which is seizing territory or mating. dont be surprised if u find a 2 inch crab. I bought some lr from a reefer whose lr had been 2 yrs+, thinking all ok but to my surprise, these lr had lots of crabs and one of it was 2"! I have gone special processes and now all of my LR are free of crabs and worms

Check to see if its the whole piece or just an empty shell.

Crabs molt all the time.

could it be octopus

the flesh its still there,its dead not molt..

sometimes i do hear clicking sound lights on or off..i though there is a mantis shrimp but found out it was my snail creating such sound when its near the glass.. but that was like months ago..

now alittle worry if its mantis shrimp..

what should i do if its a mantis shrimp?

more likely a pistol shrimp.
