Setting traps for crabs

[untamed]

I've caught a few crabs quickly using only a shot glass or a glass jigger. Just lay the shot glass at a slight upward angle (so they fall down into it) and put a small piece of shrimp at the bottom.

The last time I did it, the crab trapped himself in about 2 minutes.

(Note that you can't catch a mantis this way...they swim, while crabs can't)

BTW Bev...I've kept a good number of those Eunicid worms in my tank for many years now. They will eat just about anything, but prefer the easy meal of whatever is lying on the bottom of the tank. If you starved one, I'm still not sure that it could successfully hunt anything.

All I can tell you about that worm we caught was that there was no more slimed and disappearing bait or snails going on after the worm was removed from the tank. I don't like to kill hitchhikers that are known to be beneficial, but if there's a chance they're harmful, which we gauged this worm was, out they go!
