I've always been skepticle of this method...last night i needed to catch my red-lipped blenny who has been terrorizing my cardinal fish...i got one of the 8 oz plastic coke bottles, cut off the tip, pushed the neck into the body, put in some live rock rubble to weight it down, tossed in a few pellets of food and within 15 minutes i caught the fish...i was amazed...i love it when something so simple works...and so FREE
