When do guppy fry begin to display their colors?

Question

I have quite a few fry, all almost a month old. They are starting to show some black spots, but I'm wondering when their colors will first start to show up.

Answer 1

Very soon. Most baby guppies begin to get color around 5-6 weeks. Only a little at first then more as they reach near adult size. The black spots you are seeing is probably the first signs on color developing, black is a strong color and usually shows early.
