Unlike most corals, the Sun Corals are not photosynthetic. The Sun Corals doesn't host zooxanthellae, the symbiotic algae that provide energy to the coral via photosynthesis. Instead, they are heterotrophic, and extend long tentacles at night to catch passing zooplankton; their large polyp size allows them to take relatively large zooplankton. How Sun Corals are not photosynthetic this is a coral that needs to be feed to survive in an aquarium.
