高鳍鱼属（学名：Pterophyllum）又叫神仙鱼属，通称神仙鱼、燕鱼，是一种体形较大的热带鱼，原产于南美洲亚马逊河，体形侧扁，高可达15厘米，适合在河中水流平稳的树根缝隙中生活，以动物性水虫为食料。水温应保持26℃，繁殖水温应达27-28℃，受精卵排放附着在水草叶或山石上，雌雄鱼共同护理照料，但卵孵出后，大鱼容易吞食小鱼，也不适合和其他小鱼混养。

神仙鱼姿态飘逸，美丽大方，初发现时曾在国际引起轰动，从英文名称“天使鱼”可以看出受人喜爱的程度，但神仙鱼对环境要求比较严格，必须配备调节温度和净化水质的设施。

Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as "angelfish". All Pterophyllum species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped longitudinally, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All Pterophyllum species form **** pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed.
