Full sps reef, how to catch a powder blue?

[rastaangel]

Back when I was trying to catch a longnose butterfly that developed a taste for polyps in my 90g SPS tank I used a bunch of peices of glass to cover up all but one of his escape routes. Then that night when he was sleeping I put a few more peices in behind his fav escape route that funneled into a small clear jug. The next morning when the lights came on for feeding all I had to do was stick the net in my tank and he took off to his fav hiding place full speed which made him bulldose into the jug. Then I just put my net over it and pulled the jug out.
