Livebearer Specilest
If you still need help identifying the fish it may be difficult with that picture since there is no good angle to look at the finage and other visible signs to identify which livebearer it may be. Concerning the sex of the fish simply look if it has a gonopodium or not. If they are too young it may be hard to have a solid identification since some that may look like females early on may be males who grow their gonopodium later on. So after you know their gender i suggest splitting up the males and females unless you want a huge batch of fry all over again.
Thanks, like Harlequins and i said in my first post on this topic. I do know.
The interesting thing here and why I'm leaving it running is that the fish look's like a female with a gravid spot.
It is infact a male and this is natural colouration which Ashley1991 correctly pointed out, this is why i use a slightly blured image.
Stunning fish i think and look's better than most cultivated types i think.
