i've had great luck feeding my Condylactus with freeze-dried shrimp.
i make up two pieces, one small, one big. the small piece goes in first, and is invariably stolen by the hawkfish, who watched such activity... well, like a hawk.
the second chunk is then given to the anemone, who seems to really get into it... for the next few days he'll be larger and generally sassy-looking.
at first, i was using my hand to feed him, which works ok if your hands and arms are clean. recently i got a lond wooden dowel (rod) and attached a small brad (nail) to one end..... thread the food onto this nail (i'm looking for a suitable non-metallic substitute for the nail) and feed that way...
the anemone then really has to 'fight' for the food, in order to pull it off of the nail, plus i don't get stung as much (at all)
have fun!
