Catching my shrimp... Formidable foe!

[zum14]

So anyone have any good ideas for catching these crafty fellers? Ive tried the regular bottle trap, modified bottle trap, and even this contraption...
(Kind of a twist on a commercial shrimp trap and bottle trap)
We will see how it works tonight.
I also tried mysis, brine, pellets. The shrimp just sit there and laugh at me. I even tried putting a piece of the pocillopora (coral there attacking for some reason) in a net and just set it in the tank. The shrimp actually went into the net but as soon as i twitched it was gone like a bullet. Ive ordered a longnose hawkfish so hopefully i can get these guys before he arrives. I really dont want to tear my tank apart, its getting tough now cause the corals are starting to grow inbetween the rocks. Thanks for any help.
