Goniastrea pectinata is a reef-building stony coral in the family Merulinidae that forms massive colonies composed of closely arranged, polygonal corallites with prominent walls and radiating septa. Its colonies commonly display brown, green, gray, or contrasting oral coloration, creating a textured geometric appearance that adds a strong natural presence to reef aquariums. Goniastrea pectinata relies largely on photosynthesis performed by symbiotic algae within its tissues, so maintaining stable water chemistry, moderate lighting, gentle to moderate water movement, and sufficient distance from neighboring corals is essential for preserving healthy tissue growth and attractive coloration.
