    I've been meaning to post this before.

    A little while back I had this issue happen with my big green slimer....since stopped.

    It's now happening on this blue acro...almost as if the tips and polyps are being chewed off. I had this coral for over a year.

    could this oke be the cause?...checked the branch he was perched on (this is a different coral)...all looked ok. Incidentaly I have had these hermits for a number of years.

    With those massive claws I recon he or they could be the culprit but I'm not sure cuz I don't know the species. Do you have any other inverts that can't keep their claws to themselves?

    That look like a local hermit. one small claw, one bigger with bottom part white.
    They are normally OK. But can be naughty apparently when big. I got some now for a year. Not sure to what size they really grow. But I got no problems either from mine.

    Adee I had the same problem recently bud! Infact some of my corals are still recovering from it. At first I thought it was Angels. But after some weeks I found a crab about 2 centimeters wife with sharp black claws. It kind of chamoflaged into my Blue Stag. I had to remove the colony and sump it. You could physically see the bugger digging his claws into the corals and removing chunks.

    ok...sorry a bit peeved off at the mo...

    I removed the big purple tip acro (where the hairy brown crab lurks)....luckily this coral head rests on a spike through the base (plastic dowl).....while I was lifting it out of the water (where I was holding it)....it crumbled, and all 1.5 kilos of coral plonked back in, right ontop of my other big blue acro :banghead: which broke into about 5 pieces...

    Anyways with the coral removed....had to chop away into the coral to get to the crab which was hiding deep inside.

    So ended up butchering two corals to get to this crab....hope he is the culprit and that there is no more.

    Thanks Siyaha & Dallas, red thru that link...though I don't see any visible signs of these bugs even on the eaten portions that I broke off...will see if the "trends" continue or not.

    Glad you got the bugger, but sorry about the mishap with the other colony :(
    Adee, do you perhaps have a pic of this guy? I wana match it up to the one I caught. Is it slightly hairy with a black tip on its claw? The shape is almost identical as the symbiotic Acro crabs.
