How fast do elkhorns grow?

Elkhorn corals (Acropora palmata) typically grow at a rate of about 2 to 10 inches (5 to 25 centimeters) per year, depending on environmental conditions such as water temperature, light availability, and nutrient levels. Factors like ocean acidity and pollution can negatively affect their growth rates. Healthy elkhorn coral colonies are essential for reef ecosystems, providing habitat and protection for various marine species.
