Goniopora, often called "Flowerpot Coral" or "Daisy Coral" is a large polyp stony (LPS) coral found in lagoons and turbid water conditions. Goniopora have numerous daisy-like polyps that extend outward from the base, each tipped with 24 tentacles which surround a mouth. Goniopora Corals come in a variety of colors including pinks, greens, creams, tans, and grays. Goniopora belong to the Poritidae family.
Goniopora are sensitive corals that when probed will usually contract. Goniopora can thrive in a wide range of lighting, depending on species. High lighting is not recommended. We recommend 100-150 PAR. Goniopora corals must also have some water movement so their polyps can move freely. However, it should not be directed right at the polyps or the movement might be too vigorous and could damage the flesh of the coral. One of my favorite things about Goniopora is the beautiful movement they can add to your reef tank with their billowing polyps.
Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. They also filter-feed on the nutrients in the water column. It is a good idea to provide them with additional foods like microplankton or other foods designed for filter-feeding invertebrates. There must be adequate amounts of calcium and iron in the tank to help their skeletal development. Make sure to monitor your water levels.
Placement of your Goniopora in your reef tank is also crucial. They must be well positioned on a sturdy rock to avoid damaging falls. When placing Goniopora they must have enough room to grow and move their tentacles. Goniopora can be aggressive and will sting other corals with their sweeper tentacles.
