How quick with a net are you?

I found this:

there are easier ways to catch a crab - just find a glass and stand it up against the rockwork, then put something tasty in the bottom. Wait overnight and you should find a crab in the bottom and since the sides are smooth and they can't swim, it won't be able to get out. Way less of a headache than the methods you're all describing, plus the crab will be unharmed and can be put to good use in the sump or fuge.

^This method works very well. The glass just needs to be left so that the crab can easily crawl into it and at about a 45 degree angle so that it can't crawl back out.

I tried using the glass method and it didn't work... at first it come out and put it's legs inside it but then didn't take the lunge....I tried the 2 liter bottle method too but all that was in the bottle was peppermint shrimp....This crab is in the same hole everyday....I tried to stab him too and nothing....anyone have any other ideas?

As much as I dont like killing things. Sometimes there are no other options. With that being said, if you know which hole the crab is in. Then get 3 bamboo skewers and use 2 zip ties to tie them together forming a triangle shape. Then smash him inside the hole he is in..
