Catching a rogue crab

[The Codfather]

[quote]How do you catch them when they are feeding though? The only time I see him feeding, his body is almost completely hidden, and I can just see a claw reach out to pick stuff off the rock. Like I said, he is lightning quick, there is no way I can catch him without a trap of some sort./QUOTE]

I caught the crabs using a large piece of shrimp tied to a rock. I would place it close to the glass away from the rock work, just after lights out. This way the shrimp could only eat so much, the fish would leave it alone, and after a few days of feeding light it was quite easy to catch the crabs in the open. The only problem was the waiting game, it took several nights, but i no longer have any. Thanks,
