well some tips for your next go around: I don't feed any of my LPS very often they mostly get what floats their way during feeding I may drop pellets or coral frenzy(use a bulb yup feeder) once in a while but more importantly your parameters need to be good. check your calcium,magnesium, and alkalinity levels and go from there. also make sure you have proper lighting and filtration. again any question just ask, we are here to help.
