How often do i feed my corals?

How long have you had the tank? Very nice. Note that corals mainly need light and calcium more than particulate matter. I would feed the coral once a week or so and the fish daily; check the nitrate levels. More importantly, are you dripping calcium into the tank? That's important for the hard corals... also watch that some of those corals don't attack their neighbors. Not all corals are compatible so close to each other.
