Extreamly Colourful Guppy Fry

[Suz]

Hi all,
my female guppy gave birth nearly 2 months ago now to about 5 fry (well thats all i managed to save) one to the fry is very very colourful, the tail is black / dark blue and yellow, the body is shiny blue and it has now developer 2 organge stripes at the top of it, out of all the fry this one is the only one with this much colour on it and the biggest out the lot, does anyone know why this would happen, its great colours!

Well, they are getting mature and getting their colors! It's normal. I'm guessing this one is the dominant male, which is why he may be so bright. It's also very possible that line has been crossed with Endlers somewhere, and it's showing through, because it sounds like very Endler-ish markings.
