How to Breed Fancy Guppies
Breeding guppies begins with your breeding shoal. Breed one male to about two to three females. Ok, so it’s a tiny shoal but from those two or three females, even if you remove the male after you notice they are pregnant and never put him with them again, they will store and use his sperm to reproduce up to three litters each.
Feed your breeders well but don’t over feed them because that will cause health problems and possibly even fatalities. Micro worms, a good quality flaked food, water fleas, brine shrimp are all good to feed.
As for breeders and fry, a smaller 5 gal tank is enough as container. Guppies are not difficult to keep because they can adapt to various water conditions. A pH of 7.2 in moderate hardness is just perfect water condition for them but they can live to water that is amidst 6.4 to 8.6 provided, they are accustomed appropriately. Take note to maintain temperatures between 76 and 82 degrees for your breeders and fry while older guppies can live between 72 to 76 degrees.
The best time to separate your fry by sexes is 4 to 5 weeks after. To do this sort out enough females that you will need in planning for your next set of breeders. You can easily detect if the fry is female because in its anal fins, where the fertilization takes place, there is a dark spot directly above.
