Golden Pearls is a larval food or zooplankton substitute. It's available in many different sizes based on what the target feeder is. Generally, if you have a healthy tank, feeding the corals isn't required for them to survive. Rapid growth and many other factors can be affected by feeding, but it can quickly become a nutrient problem. Without trying to offend, I'd suggest staying the course if things are going well, and dig into artificial foods for corals. There's some research out there that's a few years old, when there was a flurry new products to market.
