Disc Coral

About

Disc coral (Turbinaria frondens) is a Western Pacific species found across shallow reefs and rocky foreshores from the surface down to around 40 meters. Its growth form is part of what makes it so recognizable: young colonies start out as simple cups, but over time they expand into broad, flattened or irregularly contorted fronds that can lean upright or spread horizontally depending on conditions. The individual corallites are small, averaging a few millimeters across, and tend to sit immersed within the surface of the colony or extend into short tubes that angle outward toward the edges of upright fronds. Coloration is typically a uniform dark or greenish-brown, occasionally shifting toward yellow or grey. It is not a showy coral in the traditional sense, but it has a real architectural quality that suits certain aquascape styles well. In the aquarium, Turbinaria frondens is considered intermediate in care. It does not demand the intense light that many other stony corals require, making it a reasonable candidate for lower-lit areas of the tank. Moderate flow helps keep detritus from settling on its broad surfaces. Reef safe and generally tolerant compared to more demanding SPS corals, it rewards keepers who pay attention to water quality without being punishing to those still building their skills.
