3 Month Johanni fry

[bruster]

So my unexpected fry are almost 3 months now, and about an inch long. They are full of color. Recently I moved them to my empty 55 gal, now that all my fish are in the 150. One thing I wanted to ask is, is it possible for them to start showing sex colors now? There are a few that have some deep black and blue colors. I will post some pics of them tomorrow if I get a chance.
