I have a endler that started coloring up before he developed the gonopodium. Some males will have a body of a female more full so sometimes they get mistaken for a female. These males are late bloomers.The gonopodium takes time to develop.It looks like a female then all of a sudden you see the gonopodium develop. Get a magnifying glass. I use mine all the time to look at the baby fry more closely. It is the best way to see the gonopodium develop in a male and see the coloring develop on a day to day inspection. It is also easier to pick out the males as they develop and separate them from the females if you are trying to breed for a certain color. If you can pick out virgin females and have a nice male you want to breed with to get the coloring you want but this is tricky . Males will mate with any female if given the chance so it is hard to get a female that is not pregnant as the females can store sperm for 6 months or more from 1 male. Most females at the pet store that is in a mixed tank are most likely pregnant already. That is why some people that have no male livebearers in their tank are surprised to find baby fish after so many months. It may take 8-12 weeks to tell sometimes.
