as far as the goniopora goes, I got them from a lfs taht had them for about 6 months in a display tank. the day I went in looking for corals he was tearing the tank down to set up a larger one. I convinced him to sell me both of them the green mushrooms and the green star polyps. All he had ever fed the goniopora was phytoplankton. In my tank I feed a frozen brine, mysis, spirulina, pink shrimp mix from H2O life Aquarium foods. I soak it in live phyto plankton every day, I feed the tank twice a day, half a cube in the morning and half a cube in the evening. I also feed the tank a hand full of live mysis shrimp once a week. the flow in my tank moves everything around and everything gets fed. I dont target feed. Ive had them for about 5 months now and they seem to be doing well. I'll have to see what happens as more time goes by.
