Guppy Fry Colours

[Ellieabbott4]

i was studying my guppy fry today and i have noticed that one of the fry looks like its got dark patches on it. could this be colouring coming through or something else?
 

 
also some of the others have electric blue tails, they look lovely when it catches the light

That blue one is soo pretty. All my fry are starting show black tails expect one and it's straight yellow. Very pretty, fish.

They were born Boxing Day so are about 5 weeks old now! I'm so impatient, I want them to grow really fast so I can see what they are going to look like and how many males or females there will be

The females have black spots on their ends. It doesn't indicate that they are pregnant, just the sex.
First picture, central fish looks like a male, 2nd picture the bottom right fish is a female(see the black dot), 3rd and 4th look like a male.

Your guppies look great.  I wish mine would start coloring...lol  I'm hoping they will soon I want to say they are about 3-4 weeks old.

Thank you everyday I look at them and I see different colours coming through. Last night I could see some red/yellow on a few of them. I have four different sets of babies in there so I'm hoping for 4 different colours. My first female only had about 4 fry, my second had about 20, my third had 45! And one just had 5 fry the other day this might sound weird but I love to just sit and watch them, I could do it for hours. They are so fascinating
