No, she is still a baby (size wise) and there are no males. I got rid of them all to stop the population explosion.
She is perfectly formed but about 2/3 the size of the Neon Tetras. If anything her fins are a little long for her size, but not by much.
It's a heavily planted tank so usually all the Nitrates get used up and not much more than 0, however I did see them get to around 20 a month or so ago, so I stepped up the water changes. All her siblings grew up though. Just this one stayed small.
