the goniopora is the one next to your angel fish in this picture

basically just pour a small amount of gooey juicy food over him occasionally
(brine shrimp juice, vitamins, etc.)

also when you algae the tank
just let the diatoms fly around the water before siphoning for a water change...
the goniopora and other corals will _ up anything edible dissolved in the water

also some DT's Phytoplankton
it's a good idea to put that in also...
small amounts occasionally...
the saltwater water column forms phytoplankton on it's own with your ref lights but it's good to add a little extra
