At work, a co-worker of mine uses those hooks from fly fishing and frozen krill. He'll chum the water, and wait for the fish he wants to get close, drop the line, and after a try or two, BOOM! Gets his fish. We jokingly call him wolf, as in the guy named wolf in Pulp Fiction, because he makes you're problems go away. This method works great on cichlids and damselfish, and I've seen it done on a wrasse in a 400 gallon rocky tank where moving stuff wasn't an option at all.
