no.
No, what you are actually seeing when looking at the gravid spot is the eggs inside the mother fish. The gravid spot does not go away until the mother has given birth to her young. The spot will get very dark before the fry are born, because they will begin to hatch out of their eggs before the birth.
Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.
The gravid spot. It indicates that the guppy is pregnant, and the gravid spot will grow larger the farther the guppy is into pregnancy. (pregnancy usually lasts about one month)
Glo fish don't have gravid spots. Gravid spots are actually the many eyes of the unborn babies of certain live bearing fish like guppies, mollies, and platies.
your guppy would give birth in the next 24 hours.
You will have to go by the size of their tummies. Once a guppy starts breeding she will always have a gravid spot.
A gravid spot is the dark area on the fish's butt.
The gravid spot on a guppy is not always a 100% determination of pregnancy as the colours can vary. Quite often, when they are ready to give birth, the gravid spot becomes quite dark.
Anywhere from between 4-60. Usually the the size of the female's stomach and gravid spot will give you an estimate. If it has been a month and the gravid spot is still somewhat small you can estimate a low amount of fry (guppy babies). If the stomach is looking like it is about to burst, you can estimate a ton of babies. Hope this helps. :)
I believe some, and the spot you're referring to is a gravid spot.Mollies, unlike guppies, don't have as much transparency to their bodies as guppies do and might not show a gravid spot (but they do have them all the same).Mollies plump up a lot when pregnant as well, it will defiantly be noticeable.You can also check the sex of the fish as well; if the anal fin (the one at the bottom of their bodies) is long, "pointed" and usually kept rolled up close to their bodies, it's a male, if the anal fin is rounded and "fan-shaped", it's a female.
No in a word all guppies are live bearers hence their almost accidental breeding at the base of the anal fin there is a dark area called the gravid spot this is present in all females nearing the time og giving birth
There will be a dark spot in front of the fishes anus (cloaca) in a pregnant (gravid) female livebearer. This spot is called the "Gravid Spot".
