I also found this on reefpedia:
Feeding information on this coral is somewhat limited. It is believed that this coral may require supplemental feeding, on top of having photosynthetic zooxanthellae algae. Some have found some success by feeding a mixture of various foods that are combined into a paste. It is thought that a required food is the highly-nutritious Cyclopeeze, which is a small invertebrate with a very high protein and amino acid content. Other foods may include clams, shrimp, DT's Oyster Eggs, and other nutritious and meaty foods.
If feeding is done, it should be done with minimal flow, using a syringe to place small gobs of the pasty food onto a good number of the polyps. When ingested, the food will feed the entire coral, so feeding each and every polyp is unnecessary. Feeding should be done about two to three times per week.
