Abstract: An efficient and stable circulating water system was constructed for coral culture, and five coral species were cultured in an Aquarium. Water temperature, light intensity, nutrient and other environmental indicators of the coral culture were regularly monitored in the aquarium, and the growth status of corals was recorded. The results showed that the water quality and illumination intensity had an important effect on the growth and reproduction of corals. The five species of corals all grew well under the conditions of water temperature at 24-28 ℃, salinity 25-35, pH 8.0-8.5, low ammonia concentration(＜0. 01 mg·L^-1), low nitrate concentration(＜0.005 mg·L^-1), low nitrite nitrogen concentration(＜0.005 mg·L^-1) and higher dissolved oxygen(＞4 mg·L^-1). Green button corals（Protopalythoa sp.） were reproduced naturally. The coral budsof Acropora cervicornis increased their length growth by 2.84%-3.42% per month, their height growth by 2.28%-2.79% per month, and their weight growth by 2.28%-3.02% per month. Illumination intensity in a range of 10 000 to 20 000 Lx promoted coral growth; different species of corals had different degrees of sensitivity to light intensity, which indicates that the corals have different saturation points in their response to illuminationight intensity.
