Goniopora is a difficult coral to care for, usually best for more experienced reef keepers. Basically, it needs a nutrient laden environment to thrive, and our tanks are often too pristine. The Red Goniopora is considered the hardier one, compared to the abundance of green ones for sale. They die slowly over time, receding from the skeletal base. Success can only be measured in years of captivity, and few are able to do so. I purchased this one from a reefer that kept it for nine months. Target feeding Cyclop-Eeze might prove beneficial, or perhaps Rotifers. You can recognize a goniopora by the 24 'petals' or tentacles of each polyp.
