well, i actually just needed to exercise a little more patience and the ol' cut off, inverted-top of the pop bottle worked after all! :biggrin: poor crab...

I have at least two crabs in my 67g that I want to catch. However, they seem to be algae eaters, so I don't know how successful I will be with my trap.

Glass with plastic wrap covering top, with a small opening for crab (and hopefully not the cleaner shrimp :eek: ):

Trap in place, baited with mysis, in the 67g. Hopefully the opening is small enough to keep the shrimp out :eek: :
