Goniopora and alveopora are a variety of corals aptly referred to as ‘flowerpot coral’. They extend long, flowing ‘stems’ and ‘flower’ shaped tentacles from their round, calcium carbonate bases. The main distinction between the two genuses are the number of tentacles per polyp; goniopora with 24 and alveopora with just 12. These corals are considered part of the large polyp stony coral category (LPS). Flowerpot corals come in a variety of colours, often found in metallic green, yellow, purple, hot pink, bright red and will sometimes exhibit varied ‘eye’ colour. It is recommended to only add flowerpot corals to established systems, with a proven record for maintaining other healthy LPS corals.
