Breeding Guppies Couldn’t be easier, it really is a good fish to start with. Breeding can be done one of two ways - you can either place the guppies in there own breeding tank or your can breed them in the community tank. There are good and bad points of both ways and here they are,
Separate Breeding Tank.
Community Breeding Tank.
Ok How do you breed guppies?
Right I’m not going to waffle on with all the scientific jargon that some sites do because you really don't need it with guppies because they really are so easy to breed but here are the things that you should know.
You tanks water temperature should be between 23-28°C
When guppies breed the male will approach the female from below and extend his gonopodium, the female guppy can store sperm for up to 3 months within her from one mate, meaning that she could have 3 births for just one mating session which is pretty cool if i say so myself but is good to know if you are select breeding you should isolate her with no mates for at least 3 spawns to allow all the sperm to be used before introducing your chosen male.
The gestation period for the female guppy is usually 28 days but can range from 21 to 40 all depending on the female and the amount of fry she is carrying. The female guppy can give birth to between
Whilst the female guppy’s is pregnant she will develop a large round belly and will also have a dark patch on her belly which is the fry which we call the gravid spot.
Try to not cause her any stress when she is close to giving birth as this could cause her to give birth prematurely which would more than likely kill the babies and another thing that could happen is she could absorb the fry and not give birth at all.
Within the tank that the guppy fry are to be born in regardless of it being a breeding tank or a community tank there should be plenty of cover for the fry to take shelter in once being born to escape being eaten by the tank mates or even the female herself! The perfect plant to use is java moss as this is quite thick and dense making it hard for bigger fish to enter providing a safe shelter for the guppy fry to grow.
Within hours of the fry being born they will be eating anything they can, you can feed the guppy fry freshly hatched brine shrimp and liquid or powered fry food. Make sure not to over feed them as the uneaten food will pollute the tank and will kill your guppy fry.
Whilst the fry are growing make sure you do regular water changes to keep the water quality ok and in turn will promote growth.
It will usually take between 1-2 months until you can determine the sex of the guppy fry.
I hope this information has helped you breed you guppies and hope you have great fun and success in breeding your guppies.
