Reproduction
Mating System
Endler’s Livebearers are livebearers, which means that females give birth to live young rather than laying eggs. The mating system of this species is characterized by the males courting the females through chasing displays. Once the female is receptive, mating occurs, and she will carry the developing fry internally until birth. Males may mate with multiple females, and females can store sperm to fertilize multiple batches of fry.
Pregnancy and Birth
The gestation period of an Endler’s Livebearer is relatively short, usually lasting around 28 to 40 days, depending on various factors such as water temperature and the female’s health. During this period, the female’s abdomen gradually expands as the fry develop inside her. When the time comes for birth, the female will release the fry into the water, and they will begin swimming and fending for themselves almost immediately. It is essential to provide plenty of hiding spots and floating vegetation for the fry to seek refuge and increase their chances of survival.
Conservation
