Before now, I wouldn't of been to tell you any livebearers except for guppies, Endlers, mollies, platies and swordtails.
Most shop-bought endlers are endler/guppy hybrids. Same with platies and swordtails. Even mollies are often hybrids between the various species.
But there's so many lovely, natural species out there which are over-looked because the common ones are the VERY colourful ones.
This is my old avatar and his missus, they are
Limia Tridens.
As with guppies, the female is the drab one, but the male had this lovely neon blue colouration. These are just the same to care for as platies/guppies, they are also poecilids, the male has a gonopodium, the female stores sperm packets for 6 months. I had some success breeding these in a fairly inhospitable tank (ie the fry were mainly predated upon, due to lack of hiding places. I originally saw 3 fry, one of whom survived to adulthood. They've all recently passed.
That one that I said I wanted to keep is a Goodeid. Males do not have a gonopodium, they have an andropodium, which is used for the same purpose, but is shaped like a mitten, and the sperm, I believe goes along the "thumb" of the mitten into the female. The female does not store sperm like the poecilids. Goodeids are often quite feisty species, and need to be in species tanks.
I'd really love to have a fish room where I could set up breeding projects for a number of these species. Many of them are nearly extinct in the wild.
