    Hi
    Can you help with an id on this crab. Took 5 months to catch this guy. Safe or not, or sump it? ImageUploadedByTapatalk1352218365.992004.jpg

    Hi Kalvyn
    The pincers look to small for a predator, but then again, the crab is still small.
    For sanity sake I would sump it.

    Nope, not a emerald... Definitely not reef safe. Sumping is a good idea.

    I agree. It is not a emerald. I have an emerald and they look nothing alike. Think I should sump it rather. He is beautiful though.

    Sump it with a small piece of liverock to hide in. Just never ever forget why the rock is in the sump.

    In the one pic, he looks green, in the other, he looks brown? What is it's actual color?
    Does the legs appear smooth or hairy?

    Ok, What it is NOT is stone crab, anemone crab, fiddler crab (female), emerald crab, shamefaced crab.
    There is a slight possibility of it being of the Mythraculus species (red), but the legs on your critter are too smooth...

    It is really frustrating that there is so little info available on all the hitchhiker crabs..
    Web is quick to tell you that it is not reef safe, but does not tell you what it is! Yet there are so many similar "baddies" and very few of them are identified...
    The fun starts when you try to identify it according to body shape, eye shape & position, pincer size & shape..:blush:

    Also, it beats studying... :lol:

    No black tip pinchers and no hair then not a gorilla crab, I would sump it, most hitch hicking are normally destructive when they get bigger.

    Riaan that is a good question. It has grown since I saw it the first time. But it did not grow that much. I had the glasses with hake in out for a week and only caught my hermits. He then just dissapeared in the live rock and then suddenly reappear. And still it gave me a hard time to catch it. Will see if I can take better pics tomorrow with proper camera. Pics are from cell.

    I have the same crabs in my display, always had them, they sneaky, do not like to be seen and vey fast..... They have not caught any fish in my tank, nor do they munch/nibble/disturb any of my coral.... I do not see a decline in any of the other tank critters....sooooo, i can unfortunately/fortunately not say if they are dangerous.... Ohh, and i have them (i think there are four) in different sizes, yet all is a little bigger than the one you have

    Sean that is good news. They are fast. And hide as they don't like to be seen. Still like him.
