Reproduction

Males establish a territory on a rock or coral surface and start clean it. Then, the male will court a female to the territory. Females then lay their eggs and the males fertilize them. After that, the male will constantly guard the eggs until they hatch. The eggs also get aerated and tended for by the male. Eggs that failed to hatch are removed out of the spawning site. The reproduction process usually lasts for about 20 minutes. Females can lay up to 20,000 eggs each. On average, eggs take about 3 days to a week to hatch. Males sometimes spawn with more than 1 female.
