Hi... Well, to be honest... this story isn't complete. For this story is only true with ovoviviparous livebearers. When it comes to true livebearers which are the viviparous livebearers like e.g. goodeids, halfbeaks, etc.... ; males don't have a gonopodium but an andropodium.Thatgirlinblack said:To the Op, I notice everyone is telling you that you've got a male, but no one is telling you how to tell!!
Livebearers in my opinion are one of the easiest fish species to sex. Simply take a gander at their analfin. If it's a female, it'll look like any other fin. If it's a male, it will look more pointy and thin, the fin has actually been fused into a gonopodium, a tube used to deposit sperm.
Once you know where to look, it's super duper easy to tell!!
