Anemone Coral

About

Anemone coral (Goniopora columna) is one of the more visually striking hard corals you'll encounter in the reef hobby, and also one of the more humbling. Native to the Indo-Pacific, it grows in short columnar formations with an oval cross-section, and what really sets it apart is the sheer size of its extended polyps, each tipped with a prominent oral cone that gives the whole colony a soft, flower-like appearance. Coloration runs from brown and green to yellow, usually with white oral cones that create a strong contrast when the polyps are fully extended. Pull them back and you'll often see the contracted tissue is a noticeably different shade. A nice identification clue. In the wild, this species is found from very shallow water down to around 18 meters and tends to form dense single-species stands, often in areas with reduced water clarity. That tolerance for turbid conditions is worth noting. In the aquarium, Goniopora has a reputation for being difficult to maintain long-term, and this species is no exception. It's best suited to keepers who already have some reef experience and a stable, well-established system. High light and moderate flow are key to keeping polyps extended and the colony thriving.
