Wrinkle Coral

About

Wrinkle coral (Psammocora columna) is a small-polyp stony coral found across the Indo-Pacific, ranging from shallow reef flats down to around 40 meters. That broad depth tolerance hints at a certain adaptability, which does carry over into aquarium keeping to some degree, though it still falls into intermediate territory rather than being a beginner's coral. In the wild it occupies a wide geographic range, from the eastern African coast out through the Pacific, turning up in the Philippines and beyond across tropical latitudes. The common name comes from the distinctly textured, almost ridged or wrinkled surface of its skeleton, which sets it apart visually from the smoother encrusting corals it might be grouped with at a glance. Coloration in captivity tends toward muted browns and greens, with the colony forming low encrusting or columnar growths depending on conditions. It is considered reef safe and gets along with standard mixed-reef setups, though like most small-polyp stony corals it appreciates stable water quality and consistent parameters over time. Moderate lighting and moderate flow suit it well, and keeping those conditions steady is really the key to long-term success. Not a flashy centerpiece coral, but a genuinely interesting textural addition to a mature reef tank.
