Daily increments of Pomacentrus coelestis, an abundant and well-studied fish, were validated for the life of the fish and depending on the location, age-maxima were estimated to be 127-160 days on reefs separated by tens to hundreds of kilometres on the Great Barrier Reef. This contrasts with congeners and other damselfishes that live for 5 years or more. Otoliths of P. coelestis were thinner and had different patterns of banding when compared with relatively long-lived congeners. It is suggested that banding patterns in P. coelestis may be related to patterns of maturation and spawning. The consequences of a short life would have a great influence on the population dynamics of this widespread species. Further, the demographics and habitat preferences of this species suggest rapid colonization and establishment of breeding populations that would quickly change the relative abundance of sympatric fishes.
蓝魔雀鲷（Pomacentrus coelestis）是一种数量丰富且研究充分的鱼类，其每日生长增量在鱼的整个生命周期内得到了验证，并且根据所处位置不同，在大堡礁上相隔数十至数百公里的珊瑚礁中，估计其最大年龄为127 - 160天。这与能活5年或更长时间的同属鱼类及其他雀鲷形成了对比。与寿命相对较长的同属鱼类相比，蓝魔雀鲷的耳石更薄，且具有不同 的带状模式。有人认为，蓝魔雀鲷的带状模式可能与成熟和产卵模式有关。寿命较短这一情况会对这个分布广泛的物种的种群动态产生重大影响。此外，该物种的种群统计学特征和栖息地偏好表明，其繁殖种群能够迅速定殖并建立起来，这将迅速改变同域分布鱼类的相对丰度。
