Xanthidae Crab! (I think)

[trinac]

I've been having luck catching crabs in my live rock with a product called the x-terminator. I bought it at www.mops.ca

I just put some bait in, mysis shrimp, and put in near the rock when the lights go out. Each time I've used it has caught a crab.

i'll tag along on this one i think i have one in my 55 gal so are they coral killers or fish eaters!

I caught 8 of these crabs in my SMALL reef aquarium!
Searched the web high and low on how to catch them and the best method I found was using a tall glass cup leaning on the rockwork with bait in the bottom.
Crab falls in after the bait and can't climb out as there is nothing for him to grip on the glass!
It worked great and cost me nothing :-)
Good luck, it took me a couple of weeks to get them.
