New_to_fish_world Posted November 2, 2009 Report Share Posted November 2, 2009 Hi all some questions A) how old does the fry have to be before you can sex them? B) Approx at what age of the male fry does its colour in the back fin appear? Thanks I am a beginner just like you to I'd like to know the same thing My babies are nearly about a month old and I see some of them have flicks of colours on their tails So I have taken that to be boys.? Will be cool to see what the others have to say tho. Quote Link to comment Share on other sites More sharing options...
Aquila Posted November 2, 2009 Report Share Posted November 2, 2009 Hi I used this website when I was first researching guppy breeding. http://guppyplace.tripod.com/Breeding.html The fry can be separated as early as 1 week if you look closely for the female's developing gravid spot - dark spot behind anal fin (this can be hard with blonde guppies as it is without pigment and comes up yellow). But like the article says, its unnecessary to be this proficient as the males do not develop their gonopodium (long anal fin) until about 3-6 weeks. Some of my fry, especially the tuxedos/half-blacks, start developing their black body pigments almost immediately after birth. This is both for the males and females. The other colours like red, yellow, and blue start to come in later. Some females will also have flecks of colour or black in their tail, but the males will have more and their tails will start growing out larger. Yellow is usually present fairly early on ~1month. The blue is also fairly early when the light hits it because its iridescent. The reds and oranges come in last >2months. The males typically don't have a tail that reaches its full size and has all the colours in their glory till adulthood. I find you get the fastest growth rates if you start the fry off the first couple of weeks in a breeding trap. Feed them as many times a day as you can (try to keep their bellies full at all times). You may need to split them into 2 breeding traps if you've had a particularly large drop. Having them in a smaller area at first help because the food is more easily found in a smaller area. I feed mine solely on baby brine shrimp at first, but many have had success on microworms. After this, move them into a larger tank 2-40L as they start to grow out. Then into a 80L. If you keep the water warm, and feed them very often and give them enough room so they are not crowded, they will grow out quicker. Hope this helps!

BikBok Posted November 2, 2009 Report Share Posted November 2, 2009 i find the easiest way to sex them when they're young is to look for the gravid spot in the females.. you can see this very early on. (often around 1-2 weeks) And in the boys his lower anal fin will start to elongate and thicken on the outer edge as it starts to become a gonopodium which for my tuxedos is around 5-6 weeks and for my snakeskins around 4-5 weeks.

Tsarmina Posted November 3, 2009 Report Share Posted November 3, 2009 just remember this: 1, all females have a gravid spot 2, only females have a gravid spot that make's it a little easier too Quote Link to comment Share on other sites More sharing options...
Dimsum Posted November 3, 2009 Report Share Posted November 3, 2009 If you are trying to sex them at a very young age, I find using a torch helps. Also don't confuse body pattern spots with gravid spots :oops: If in doubt move it into the male tank. Quote Link to comment Share on other sites More sharing options...
