| Care Description | Porites are a Genus of small polyp stony corals (SPS) that are somewhat uncommon to the reef aquarium hobby. Most of the time they grow finger-like structures from a massive encrusting base and come in a variety of colors. Porites are rarely known by their common name “jewel coral.” For some corals, their scientific name tends to stick. Please see below for additional care tips for Porites. |

General Description
Porites corals are part of the small polyp stony corals (SPS) genus, known for their finger-like structures growing from a massive encrusting base, with a variety of colors available. They are also referred to as "jewel coral" in some cases due to their vibrant appearance, and particularly the Grinch Porites showcases a deep green base and bright red polyps.
Demands and Hardiness
These corals thrive under high lighting conditions and are generally uncommon in the reef aquarium hobby. They prefer strong water movement, as they typically grow in areas with heavy flow on the reef. Porites corals feed on the smallest particles, such as Phytoplankton and Zooplankton, making liquid and powdery foods suitable for their diet.
Lighting
Porites corals are typically found in very shallow waters in the wild and, therefore, require intense lighting in aquariums. Metal Halide lighting, a large bank of high output fluorescent lights, or full-spectrum LEDs are recommended to provide the necessary light intensity for optimal growth. Around 200-PAR is ideal, although shallow water varieties may receive over 1000-PAR.
Water Flow
These corals thrive in strong water movement, akin to the heavy flow areas they grow in on the reef. Therefore, maintaining a strong water flow within the aquarium is essential for the health and growth of Porites corals.
Feeding
While Porites corals are not known for their appetite, they often host Christmas tree worms that are beneficial filter feeders. Regular additions of phytoplankton and smaller zooplankton can benefit both the worms and the coral itself, ensuring proper nutrition and overall health.
Propagation
Porites corals have been extensively propagated in captivity and are considered excellent candidates for aquaculture. Their ability to adapt to tank conditions and their hardiness make them a popular choice for coral propagation efforts.
Localization & Habitat
Porites corals are native to the Indo-Pacific region, particularly found around islands such as Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. They are commonly found in shallow waters with intense lighting and strong water flow, emphasizing the need for replicating these conditions in aquarium setups.
