Sun Corals are one of the more challenging large polyp stony corals (LPS) due in large part to the fact that they are non-photosynthetic in nature. Because they are non-photosynthetic, they are incapable of deriving any nutrition from photosynthesis and require constant feeding for survival. Unlike filter feeding non-photosynthetic corals, Tubastrea and Dendrophyllia sun corals can eat larger pieces of meaty foods which make them substantially easier to feed. Still, they require food frequently (ideally several times per day) which make them a challenge to keep long-term in the home aquarium. We recommend them only to aquarists familiar with the challenges of non-photosynthetic corals and have aquariums specifically designed for their care.
