Basic Info

The gentleness of the Black Molly makes it an attractive fish. However, the Black Molly's appearance is also an extremely attractive feature. They have a completely jet black body, with large streaming dorsal fins. There have been some slightly colored variations produced by man, which are also very beautiful. Their fins resemble those of Beta Fish. Males and females are easy to distinguish visually. The male Black Molly has a larger, pointed dorsal fin. The dorsal fin on female Black Mollys is smaller and more rounded. In addition, like other livebearers the male has a sex organ called a gonopodium, which acts as a sperm-delivering device (similar to a penis in mammals). The female does not have a gonopodium she has a vent. Their short life span is the only connotative feature of the Black Molly. They will only live to be three years of age in an aquarium.
