I use tongs to feed my anemones silversides , table shrimp , and krill . I also feed zooplankton with a syringe with air tubing . My clowns also grab the frozen food I feed the fish and feed their anemones .
You dont have to feed all...some can live just fine with proper lighting...the zooxanthellae will feed them..Just like with many corals....I never directly feed mine..they do snag some of the fishes food that floats within reach though...
