filter feeder food?
 

i am wondering what type of filter food i sould get ?there seems to be 4 or 5 different kinds from kent <do they all do the same?>i have 6 or 7 feather dusters/a duncan and a bubble tip in tank .just would like know what kind works best .thanks

The feather dusters will probably benefit from some live phytoplankton... not the dead stuff Kent sells. Your duncan and bubble tip contain photosynthetic algae and so they do not require feeding (your lighting should be sufficient). But if you want to feed them the duncan will eat larger bits of food like mysis shrimp and the bubble tip can take even larger offerings like krill and silversides.
