Besides fresh clam, I have success with frozen cooked clams which u can get from ntuc/giant. In addition, my own killer food mix also includes frozen scallop, sotong, oyster, mussels, prawns and cyclopeeze. Just cut up the frozen seafoods into cubes and dump into a food processor. Add spirulina powder and garlic juice and end product is a paste form. Then I just pack them into empty frozen mysis cube tray for easy use everyday. My angels, tangs, cardinals, chromis,... etc all love it. Even newly bought MI also fell for it. Try mixing your own and u will get darn great satisfaction seeing your fishes pigging them away...
