I would be feeding the fish some flake, some frozen mysis and ocassionally some frozen cyclopeeze. Probably one light feeding a day to start out. I'd target feed the anemone something larger (pieces of chopped table shrimp, fish, etc.) occasionally (say maybe twice a week). JMO...
Care to post pix of your anemone? You can feed it directly by dropping a chunk of shrimp or something on the anemone. It will handle the rest.
Also a question for smart types ... it's ok to not feed the anemone, right? I have a similar anemone hosting a porcelain crab. I want to keep it small, so I haven't been feeding it. I was told this is ok as the anemone will happily survive on the nutrients it gets from its symbiants. It was said that if I want the thing to grow, I should feed it.
