The average is 28 days, although gestation can be prolonged by several months.
The gestation period can be affected by water conditions or other stress factors for the pregnant female. Severe stress can even cause the foeti to be aborted.
Most of the time, they're already pregnant. They can use the sperm over and over again. So your guppy could get pregnant 3 times one after another with no male guppy in the tank. Guestimation is 28 til' she gives birth.
While the gestation period is often about 28 days, it can range from 21 to roughly 40
Guppies have a gestation period of about 28 days but have been known to take as long as 31 days
Pregnancy time Can vary depends on its situation, if stressed while pregnant they can end up not having them and after a while die.
About a month.
All that is needed is a male guppy in with her.
Under normal circumstances every female guppy you come across will be gravid (pregnant). My advice is don't worry about it she will be pregnant.
The Gravid female will have the dark "gravid spot" in front of her vent. I can however assure you that if there has been a male in the same tank with a female guppy for any reasonable length of time she will be gravid.
Depending how old it is, if it is an adult female and it is in with male guppies then it is very likely that it is pregnant. (:
female guppies can produce 2-3 genaration in a year
The female guppy will develop a dark spot on the side of her belly during pregnancy. As the pregnancy progresses, the spot will grow darker.
there is not much difference but it is actually not called a fancy guppy its called a fancy tailed guppies because they have beautiful tails but beware if you have a male and female guppy or fancy tail guppy in the same tank the female will get pregnant and after the babies are born you must separate them or most of the babies will be eaten but beware the babies you can hardly see.
If your female guppy has been in a tank/container with a male since it reached maturity it will be gravid (pregnant). Give it time. The fry will come eventually
I believe that female guppies can store male sperm in their bodies until the environment is just right and then they will use it to become pregnant at will.
Answer 1:About a month. Well, that's when female FANCY GUPPIES can get pregnant!Answer 2:While it is true that guppies reach sexual maturation at about one month, they do not reach adulthood until around 12-14 weeks (~3.5 months).
Female guppies are larger and plainer. The male is distinctive for his long, flowing, colourful tail and generally brilliant colours.
The female gets a deeper tummy and there is a dark (gravid) spot by her anal fin.
