During courtship, males visit a specific area on the reef with the hope of attracting females. At sundown, about 3 to 5 females will gather with the visiting males’ disseminating their sperm among various females. A victorious male is joined by a female with the pair aligning themselves belly-to-belly, rising slowly above the reef. The offsprings remain plankton and have no parental guidance before sitting on the reef, thus selecting an appropriate habitat for the next 15 years. With a small number of females and a high male count, females favor bigger and stronger males when mating.
