How Long Does A Molly Stay Pregnant? Understanding The Pregnancy Duration

Determining whether a Molly fish is pregnant involves observing various indicators that provide valuable insights. When examining a pregnant Molly, one should pay attention to several key signs. These signs encompass a visibly enlarged belly, a heightened appetite, the emergence of a gravid spot on the lower abdomen, an abrupt preference for warmer regions within the aquarium, and notable shifts in behavior, including increased aggression or a tendency to hide. These telltale signs, as of August 17th, 2023, can help aquarists identify and understand the pregnancy status of their Molly fish more effectively.

The duration of the birthing process for Molly fish can vary widely, typically spanning from 1 to 24 hours. It appears that your Molly fish gave birth during your absence, but unfortunately, the other fish in the tank consumed most of her offspring. This incident occurred on February 28th, 2019. Understanding the timeframe for Molly fish giving birth is essential to ensure their safety and the survival of their fry.
