Feeding corals and anemones

ohh, you got the freeze dried powder stuff? i have the frozen, so it woudl be hard for me to tell you how much to feed..... but your anenome can survive if you ar ejust feeding this assuming you have good lighting. if you want to give it more, then any meaty foods would be great ranging from frozen to pellets.
as far as your other corals, all will love the stuff, except maybe the pulsing xenia. to my knowledge, no one knows why it pulses, some believe it is feeding, as the tenticles do appear to be fine filters, but i dont htink it is entirely known. IMO/Guess, i would think it eats very fine particles and organics like phytoplankton jsutdging by the size of the "filter" lookign tenticles, as well as its high survival rate in high nutrient systems while it often fails in very established, heavily skimmed sps tanks. but that spreads quickly enough without having to be fed. lol
your yellow polyps will grow like CRAZY with often feedings. i feed every week or two. some peopel will feed corals more, some less, some dont feed at all.

The xenia are believed to pulse in water with minimal current, trying to create their own. i have also read they do this because they absorb iodine etc. And adding iodine to my tank has increase the growth of my xenia. They will not eat food though.
