To catch a coral-munching blenny

[ScubaSteve]

Sooooo.... Seems my combtooth blenny has all of a sunned taken a great liking to all my SPS. Bugger has to go!

Over the past few days I saw a few bitten tips on one of my colonies and I was suspecting either the blenny or my coral beauty. Last night I was sitting on the couch and I could literally hear the tips being crunched off my milli. Turned the lights on and sure enough a bunch of tips were gone. The only one that seemed awake was the blenny (he lives in a crevice surrounded by the afflicted SPS colonies). Red handed.

Now the question is: how the hell do I get him out without tearing apart the tank? Any tricks?
