In most species of fish, the male fertilizes the eggs after they are laid. However, guppy eggs are fertilized by the male while they are still inside the female’s body. The eggs develop into tiny miniatures of their parents that are born alive and ready to fend for themselves. May 29, 2022 (source)
To dispel misinformation and myths once and for all, guppies cannot change sex and are not hermaphrodites. Females need males to fertilize their eggs and produce offspring, but they will also store the males’ sperm several months for when males are not available. Jan 20, 2022 (source)
Despite what television might have you believe, zombies aren’t running around and having romantic interactions with the living. Usually. But one species of fish does reproduce posthumously. Female Trinidadian guppies store sperm from males that they mated with. Jun 6, 2013 (source)
Although it’s not possible for a female guppy to get pregnant without a male, it can appear that she did. Research has shown that a female guppy can hold a male guppy’s sperm for 10 months or possibly longer. This may give the appearance that a female guppy is pregnant without being in the presence of a male. Apr 25, 2022 (source)
Gasparini had found that an interaction between ovarian fluid and sperm resulted in sperm from a sibling travelling at a slower pace than from an unrelated male, reducing the success of that sibling’s sperm. May 7, 2014 (source)
Colorful Guppy Babies are Male If faint streaks of color are limited to the tail only, then they’re most probably females. Because males display more impressive colors compared to females, you may be inclined to keep an all-male aquarium. May 23, 2019 (source)
Yes, they do. Though guppies are one of the calmest breeds and are generally pretty peaceful, they often end up eating their fry. This weird and disturbing activity is termed as filial cannibalism. (source)
But is it possible? You can keep only male guppies in a tank. However, when you keep only male guppies in a tank, you will see a lot of aggression and bullying among them. To spread out the aggression, it is recommended to keep at least 6 male guppies in a male-only guppy tank. May 14, 2021 (source)
Typically, the fry are delivered one at a time, although they may appear in quick succession with pauses between groups of babies. The baby guppies are usually born curled into small balls, just as they matured in the female’s womb in this compact shape. (source)
Male and female guppies have very different body types that become quite obvious as the fish mature. Males are smaller overall, and their bodies are long and thin. Females grow much bigger than the males, and they have much heavier-looking bodies. The female’s body is much more rounded compared with the male’s. (source)
Tank-kept guppies generally live for between one and three years. However, in rare cases, some individuals can make it to five years when kept in perfect conditions! Genetics also plays a part in guppy longevity, as does the care and diet the fish receive. Jul 24, 2021 (source)
After Your Guppy Gives Birth After your female gives birth, separate her from the fry, either through the use of a mesh or another tank. This is necessary as she may eat the fry, seeking the nourishment she needs to recover. Isolate her for one to two days. During this time, feed her well and regularly. Aug 9, 2021 (source)
Usually, guppies will give birth to live fry. How many though? A guppy female can give birth to anywhere from 2 to 200 fry at a time. Apr 7, 2022 (source)
Guppy pregnancy lasts for roughly a month from conception. First-time mamas deliver about 12 to 30 babies over a period of several hours. Veterans may gift you with 50 to 80 or more fry in a few hours. (source)
