I usually feed my LPS corals with mysis shrimps once a week. When the tentacles come out, LPS will grab and hold on to the food before closing up on it. Mysis shrimps are good size and you get good growth with it. I usually do it 2 days before a water change so that I can clean the polution afterwards
No other additives. Actually, most of your corals can "eat" mysis shrimps!
As was mentioned above, the yellow Gorg does look nice but it is very hard to keep them alive for longer periods as they are NOT photosynthtic.
