The variatus platy (Xiphophorus variatus), also known as variable platyfish or variegated platy, is a species of freshwater fish in family Poecilidae of order Cyprinodontiformes. A live-bearer, it is native to southern Tamaulipas and northern Veracruz states in northeastern Mexico. It is a popular fish in the aquarium trade due to its prolific breeding, as are hybrids with other members of its genus, most notably the southern platyfish.
The variatus platy grows to a maximum overall length of 7.0 cm. In the wild, they are olive in colour with black marbling or spots on the side of the caudal peduncle. Large males show blackish blotches on the dorsal fin. Unlike some other members of the genus, X. variatus has no claw at the tip of the fifth anal fin ray. The fourth pectoral ray shows well-developed serrae (saw-like notches). They typically have 20 to 24 lateral scales, 10 to 12 dorsal rays and two rows of jaw teeth.

X. variatus is endemic to the Atlantic slope of Mexico from southern Tamaulipas south to northern Veracruz. It is considered uncommon across its range. The species has also been introduced and become established in a number of locales, largely due to releases related to the aquariums trade. In the United States, they have been established in canals along the eastern shore of Tampa Bay, Florida, as well as in Gainesville. They are also naturalised in springs in the counties of Beaverhead, Granite and Madison in Montana. The species has been spread to a number of other countries outside of its range, including Colombia, Singapore, and Hong Kong, the latter of which reports a negative impact on native species due to its prodigious breeding.
The fish's habitats include slow-moving waters of vegetated canals, ditches, and warm springs.Omnivorous, its diet includes both plants and small crustaceans, insects, and annelid worms.

月鱼能与剑尾鱼杂交,经人工优选培育,至今已在体色和鳍色上产生许多不同色彩的月鱼,非常美丽。有红月 月光鱼鱼、蓝月鱼(银蓝色)、黄月鱼(橙黄色)、黑尾黄月鱼、黑尾红月鱼、花月鱼、金头月鱼,还有一种竖琴型月鱼,更新奇,等等。这些已经稳定的新花色月鱼,不宜与剑尾鱼混养,不宜与原种返交,以免出现不理想的变异或者返祖。
该品种最常见的月光鱼,在水族店肯定能看到。令人感到惊讶的是,很多月光鱼的原种就具有这种红色。如图片中的雌性个体那样,体型圆乎乎的,煞是可爱。
该品种因拥有如夕阳那样美的体色而得名,是常见月光鱼的品种之一。因体色发亮,在水草水族箱内尤为显眼。让这种鱼成批的群游的话,更能增添水族箱的魅力。该品种拥有淡淡的色彩,是极具魅力的日落月光鱼金黄型品种,在深色调的水草布景水族箱内反而更醒目。乍一看似乎很纤弱,其实其饲养和其他月光鱼一样饲养。
这是将红月光鱼的背鳍改良为高鳍型的品种。大大的背鳍给人一种优雅的感觉,比红月光鱼更具存在感。在购买时最好选择背鳍漂亮的个体。 月光鱼本品种是将红月光鱼的尾鳍改良成针尾型的品种。虽然没有高鳍红月光鱼那样的存在感,但也是一种纤细,招人喜爱的品种。尽量避免将之与啃鱼鳍的鱼混养在一起。
蓝色系月光鱼的代表种类,是给人以最自然感觉的月光鱼。这种月光鱼还给人一种清凉感,煞是可爱。遗憾的是由于其人气被体色艳丽的品种压倒,因此最近看到这种鱼的机会不太多。本品种是蓝月光鱼的胡椒型,而且是高鳍品种,溜圆的体型很可爱,与体形不相称的大背鳍实在是很有趣。看到这种品种的机会不很多。 月光鱼 月光鱼像这样各个鳍呈黑色的品种被称为黒鳍型,该品种是红月光鱼的黒鳍品种。各个鳍由于有黑色,给人以优雅的印象,其饲养与红月光鱼等其他月光鱼一样容易。
这种鱼是红太阳月光鱼的黒鳍品种,是非常常见的月光鱼。明朗的体色与黑色的鳍形成强烈的对比,在水族箱内极具魅力。在购买时,以选择鳍呈现明朗黑色的个体为佳。 月光鱼该品种因全身除头部之外都有色彩,看起来像是戴着钢盔一样而得名。乍一看可能会给人一种质朴的感觉,但仔细观察你会发现黑色的部分如金属那样闪闪发亮,非常漂亮。
该鱼尾鳍所带的花纹被戏称为米老鼠,非常招人喜爱,特别在小孩子中很受欢迎。在购买时,以选择尾鳍花纹清晰的个体为佳。
