    red light at night and tweezers should do, but you have to be quick. If not that, make a trap. Or, follow him and see what rock he lives in, get that rock out and go from there.

    Someone suggested a while back to use a net. Put some food in it and wait...when the crab goes into the net to get the food, you've got him.
    Haven't personally tried that though.

    The only luck I've had was to watch where they ran to hide & get that rock out of the tank. Even still digging a crab out that doesn't want to be dug out is a sport.

    Admittedly doing this in a 10G & a 90G is much eaiser than in a 500G tank, but hey now you've got a good excuse for that PADI course

    Good luck with it.

    Cheers!
    There is nothing so permanent as a temporary measure.

    I got back last night from a business trip that took me through Oakville....so I stopped at the ORG. I purchased a small rock with some nice zoos, but when I got home, found no less than two hichhiker crabs . They looked very similar to Emerald crabs, but were black, and had white bands on the legs.

    Ii friend of mine had a problem with a crab, he put a glass cup near the crabs rock then put some food in it, he can't climb the glass so he just removed the cup from the tank with the crab in it. no need to remove the rock

    Do Emerald crabs nip at corals?

    They love algae, especially bubble-algae.
    Emerald crabs are considered safe. However, if you have a crab in your tank and you're not sure if it is an emerald, best to get rid of it.

    a good way to get it out is to just remove the rock that u see the crab hiding in, if it;s a small enough rock that u can take it for a bit
