Robust Ivory Tree Coral

About

The robust ivory tree coral (Oculina robusta) is a reef-building species native to the subtropical waters off Florida, where it grows in protected, often turbid coastal environments at depths down to around 30 meters. What sets it apart visually is its tree-like growth form. Thick, upright branches that taper toward their tips and grow from a solid, sturdy base. The corallites are neatly circular, averaging about 6 millimeters across, and are spaced further apart on the lower portions of the colony, then pack in more tightly as the branches narrow toward the top. Coloration is a warm tan to yellowish-brown, which is modest compared to the flashier corals many hobbyists pursue, but that understated look suits a natural, species-appropriate display well. In the aquarium, this species is considered reef safe and doesn't demand intense lighting, making it a reasonable candidate for tanks that run lower-output fixtures. Moderate water movement suits it fine. While it isn't the easiest coral to keep, it isn't the most demanding either, placing it comfortably in intermediate territory. Hobbyists with some coral-keeping experience under their belt and an appreciation for less commonly kept Atlantic species should find it a rewarding and distinctive addition.
