Common name: Lesser knob coral

General information

Cyphastrea decadia is a species of hard coral that is appreciated in the reefkeeping hobby for its robustness and vibrant colors. This coral is part of the Scleractinia order, commonly known as stony corals. It is characterized by its encrusting growth form and small polyps that can display a variety of colors, often with contrasting mouths or centers.

Care

C. decadia is a relatively hardy coral that can thrive in a range of lighting conditions, from moderate to high. It is important to provide turbulent water flow to mimic its natural environment and to facilitate feeding and waste removal. This coral benefits from the addition of calcium, alkalinity, and magnesium supplements to maintain the water chemistry needed for skeletal growth.

Habitat

Cyphastrea decadia is found in the Indo-Pacific region, typically in shallow reef environments. It often grows on reef slopes and in lagoons, where it can form extensive colonies. In the aquarium, it should be placed in areas with ample water flow and sufficient lighting to promote growth and maintain its vibrant coloration.
