- Guppies (Poecilia reticulata) are livebearers, meaning they give birth to live young rather than laying eggs. Guppy females can give birth to dozens or even hundreds of fry at a time, and some females may have several broods in a single day.
- Molly fish (Poecilia sphenops) are also livebearers and can have multiple broods in a day, with each brood consisting of several dozen fry.
- Swordtails (Xiphophorus hellerii), another type of livebearer, have a similar reproductive pattern and can give birth to multiple broods in a day, with each brood containing several dozen fry.
It is important to note that while these fish can give birth multiple times in a day, the frequency of births and the number of fry per brood can vary based on various factors such as species, age, environment, diet, and breeding conditions.
