When can i tell the sex of my guppy babies?
Hello again, I am still learning. How long before I can tell the sex of my babies? I have approx. 30 new guppy fry... 3 are 1 month old, 11 were born day before yesterday and 16 today. I am having trouble telling on the month old ones.
Guppies are mostly distiguishable by their color. Males are much more colorful and have more flowing tails. Females are also slightly larger. If they haven't developed color yet than you can tell by the gonpodium fin that males have. Also, females and males in the same tank will result in a pregnant female as soon as she is mature. They will develop a dark gravid spot.

Huh that was supposed to be a link to the page...
Oh well :lol:
fishkeeper... that is why I want to separate the girls from the boys..... as they are just a few days old they don't have color yet.... *S*
Anal fin and color development is often noticed after it's a bit too late due to the size of those little fins and the timing with which the differences start to show. However, as you gain experience you will start to see the development earlier and earlier (fin develpment can be noted as early as 3-4 weeks)
Here is a bit on how to do it if you REALLY want to know as early as possible - but it's a bit involved:
Thank you zivaD... I am looking forward to seeing how many males to females I have now.. *G* .... I don't need 500 fry *S* so separating them I will be doing as soon as I can tell. If I am not sure I will place them in another tank. keeping them separate till I know for sure.
