What temperature range is optimal for coral growth?

The optimal temperature range for coral growth is between 23 to 25 degrees Celsius. At this temperature range, corals, which are sensitive to changes in their environment, are able to maintain a stable and efficient metabolic rate. This promotes photosynthesis in their symbiotic algae, known as zooxanthellae, which provide essential nutrients to the corals through the process of photosynthesis. Additionally, the favorable temperature supports the overall health of the coral, contributing to growth and reproductive processes.

Temperatures lower than this optimal range may inhibit coral metabolism and growth, while temperatures above can lead to stress and potential bleaching, as corals expel the zooxanthellae when water temperatures become too high. Therefore, maintaining a temperature within 23 to 25 degrees Celsius is crucial for the health and sustainability of coral reefs.
