    The crab i have in my tank ate one of my turbo snails i seen it drag the snail into its rock, but now i have not seen the crab for over a month, is this because the crab as had its fill and will not be on the hunt again for some time, i really need to get it out but can not locate it, any suggestions?

    keep buying snails to feed the crab. A snail is an easier target for him and cheaper than your fish. You could just try to find it and take it out.

    You could set up a trap with snail bait in it.

    Gorilla Crab!!! :eek:

    hairly brown sharp-pinchered creatures straight from Reef Hell....[​IMG]

    Had to deal with one many years ago that rode into tank on some LR.

    Shredded feather dusters, killed snails and even had an appetite for zoa's...if did not eat them, just pulled them apart for fun. :-[

    Not only deadly, but also very quick and smart.

    Took me many hours over a few days to finally catch it. Used every kind of trap found on web for catching such a thing...

    No luck. It was quick, fast and smart, usually disappearing for hours after tank is approached or something new in it...like a trap...glass, bottle, whatever.

    Finally made a miniature crab trap like I have out in garage, bridle veil stretched over a small circle of wire...multiple lines...baited with good sized piece of fresh shrimp...

    Shoved trap under sand so only shrimp sitting on surface....

    Then waited, waited and waited some more before the crab approached bait...

    When it finally tasted shrimp, would not let go of it, and easily pulled up and out of tank.

    Crab still resides in my freezer somewhere....:angry:

    Get mad...go on warpath....devote all spare energy and time to getting the little murdering SOB out of tank...(unless you enjoy seeing all your pretty corals and inverts eventually ripped to shreds...:-/)

    Good Luck!

    place a glass cup on the bottom of the tank in the sand so the top of the cup is just above the sand. you could tie down a piece of shrimp with fish line on a small piece of rock rubble. the crab will enter the cup to eat the shrimp and will be unable to get out. the cup needs to be about 2-3" high and about 1-2" wide.

    Good idea will give it a go, wat if the crab does not come out for say 3 hours, will the shrimp not pollute the water?

    crab probably wont come out right away, place prior to lights going out and wait with a red flashlight in hand from a distance, they spook easily, patience. the shrimp wont bother the tank, but other critters may want to check it out also. with stars and other crabs you may have to feed the tank so not to have them steal the bait.

    I got a few in my tank...I used a chopstick to crush them and a piece of shrimp on a stick for bait...even if he runs in a hole stick the chopstick in forcefully and im sure something will be hurting in that hole

    does anyone have a picture of this nightmare...I think I may have one! Our poly jaw has been sick & he snatched him & started to eat him, my husband netted the poly jaw but he died. Does the crab have yellow eye's?

    our 3 clowns are gone too, though the smallest was sick, but the next morning all the clowns were gone!! Is this crab able to catch fish at night while they hover at sand level & attack?
