Cockscomb Cup Coral

About

Cockscomb cup coral (Desmophyllum dianthus) is one of the most geographically widespread corals on the planet, found from subtropical seas to near-polar waters and spanning depths from shallow reefs all the way down to 2,500 meters. That range alone tells you this is not your typical reef-tank inhabitant. In the wild it is most at home in the cold, dark depths of the ocean, and its aquarium requirements reflect that. It needs genuinely cold water that most coral keepers simply cannot provide without a chiller. The colony form is solitary and cup-shaped, giving it a distinct, almost sculptural look compared to the bushy or encrusting corals most hobbyists are used to. Because it comes from low-light, deep-water environments, it does not depend on photosynthetic algae for nutrition the way warm-water corals do, which means feeding is a central part of keeping it healthy. This is a species for patient, experienced keepers with the right equipment, primarily that cold-water setup, and a genuine interest in the less-explored corners of the coral hobby. It is reef safe and not aggressive toward neighbors, but its niche requirements make it a poor fit for a typical mixed reef tank.
