Guppy colors?

[flutterbye75]

Could anyone tell me at what age do guppy fry take on coloring? I have 3 week old fry and they still have no coloring. The female guppy was pregnant when I got her so I dont know what the male who fertilized her looks like.

Thanks

You should see color around 3 to 4 weeks.
What is the temp in your tank? The temp effect the speed at which these fry would develop.
But also keep in mind that female to male ration is skewed in guppy breeding.
What is the pH level of your tank?
This along with the temp, also determine the sex of your frys.

Temp is at 79 and the ph is about 6.8. Some of the fry have grey on their tails, other than that they are with no color.

Also, dark colours will show up first. Yellow, for example, will take a much longer time.

How does the pH and the temp determine the sex?

Grey comes first! That's a good sign.

It actually depends on the parents. I have actually had yellow guppies and the fry are born with the yellow coloration. But the problem with this is that the other fish found the easy targets while the grey fry were able to hide and blend in, made themselves less of a target.
