Why did your platy die after having babies?

There are several potential reasons why your platy might have died after giving birth. Stress from the birthing process, especially if the environment was not optimal, can lead to health complications. Additionally, the energy expenditure during pregnancy and childbirth can weaken the fish, making it more susceptible to disease or other health issues. It's also possible that underlying health problems were exacerbated by the stress of giving birth.
