Pregnant Guppy Symptoms

It’s pretty easy to tell if your Guppy is pregnant or not; all you need to do is take a clear look at it. Here are some signs that you should watch out for:

  • A guppy that is pregnant will have a dark spot on the underside of her abdomen, near the anal vent. This mark is known as the gravid spot. The spot becomes dark once the eggs of the Guppy are fertilized, and it increases in size as the pregnancy progresses. It is a pretty easily noticeable sign of pregnancy in guppies.
  • The stomach of the Guppy will become square-ish instead of getting rounder.
  • Close to the end of the gestation period, the belly of the Guppy, as well as the gravid spot, will appear rather large.
  • A blond or albino guppy would have a dark maroon colored spot on her belly.
  • A female guppy might become super still and will sit in the same place and not really swim. Usually, a pregnant guppy will try to be as close to the heater as possible, or stay in the corner of the aquarium and hide in plants or behind decorations trying to isolate herself from other fishes.
  • The Guppy might display aggressive behavior like chasing when the male tries to mate with her or fin nipping.
  • Increasingly rapid breathing is also a major sign of pregnancy
  • The pregnant Guppy will continuously flex her spine so that the tail moves upward; it will seem like the fish is swimming in one place or just shivering. At that moment, she might be having a contraction.

When the Guppy is close to giving birth, you can see the eyes of the fry through the translucent skin of the fish.

How to Guppies Get Pregnant

When it comes to Guppies, the mating ritual is a bit different as compared to other fish. Most fish just lay their eggs, and then the males fertilize them by releasing sperms. This is not the case with guppies.

Male guppies can develop their sexual organs as early as about three weeks old. Male guppies tend to chase the female Guppy all around the tank as soon as they are ready to mate. The female Guppy will try her best to avoid the male and swim away from him until it gets tired and is unable to do it; that is the time when the mating process begins.

The male guppy deposits sperm into a female guppy, the female Guppy then stores that sperm and uses to over eight months. Most fish experience fertilization externally, but guppies take the internal fertilization route.

Pregnant Guppy Care

When a pregnant female Guppy shows signs that it is about to give birth, then the best thing to do is to move the Guppy to her birthing tank or a net inside the fish tank. The only thing you need to make sure is that the Guppy is isolated from other fish in the tank. This will help the Guppy give birth without any tension. There are many birthing tanks out there that mostly have partitions that provide the baby guppies with a safe place to begin swimming because fry gets eaten by many fish, which includes the mother Guppy.

The Live Birth

Guppies are different from other fish when it comes to giving life to offsprings. Guppies like most fish do not lay eggs; they actually give birth to live free swimming babies. The number of babies a guppy will have varies; guppies can give birth to 2 to 200 fry (baby guppies) at a time, taking about 6 hours. In many rare cases, guppies have been known to give birth for about 12 hours at a time. Sometimes guppies give birth to a few fry then they pause for a few days and then give birth again.

After the Guppy has given birth, she should be placed in a quiet tank for the very least a couple of hours. This gives the poor Guppy the opportunity to recover her strength and relax before joining her fishy friends back. You also make sure that the Guppy is well fed so that she has the nutrition and energy she needs in order to recover. If the batch she gave birth to was large, then the Guppy might take a full day or even two in order to recover enough. Do keep in mind that if you isolate the Guppy for a long period of time, she might end up getting stressed.

How to Identify a Male Guppy and a Female Guppy?

The body structure of the male and the female Guppy is different in many ways. They both have distinct physical characteristics which can set them apart. Like most animals, the male Guppy is much more vibrant colors as compared to the female Guppy. Males have tails and bodies which are covered in blue, orange, green, black, violet, and white spots and stripes. The males actually use these beautiful colors in order to attract a female.

Just keep in mind that these vibrant colors are not a sure way to set both the genders apart. There are many guppy species in which the female Guppy carries many vibrant colors as compared to the male.

Female guppies are much rounder and bigger than the slender, long-bodied males. A female guppy can even be twice as big as a male guppy.

Female guppies can group up to be 6 cm on average while the male guppies are about 3 cm in length on average.

The gravid spot is actually the dead giveaway. While you examine the body of your Guppy, you should also check whether the fish has a gravid spot located on the underside of its body, close to the tail. If present, then this is a pretty clear marking that the Guppy is a female. Male guppies do not have a gravid spot. If a guppy gets pregnant, then her gravid spot will get bigger as well as darker as the pregnancy progresses. Once the female gives birth, the gravid spot will again lighten up.

The tail fin of the Guppy can also help you tell both the genders apart. Female guppies have short caudal fins, which are rather narrow, male guppies on the other have long and wide caudal fins that often have elaborate patterns and are brightly colored. The dorsal fin is also another dissimilarity between the male and the female guppies. The dorsal fin is present on the top of the fish, about two to three inches from the head of the fish. Female guppies have short dorsal fins, while the male has longer dorsal fins that trail in the water as they swim around.

The anal fin is present on the underside of the Guppy and is the smaller fin before the tail fin. Female guppies have a short anal fin which is shaped like a triangle. The gravid spot is located right on top of the anal fin. On the other hand, the anal fin of the male Guppy is long and narrow, with a partially pointy end.
