Is my guppy pregnant or close to giving birth?

To determine if your guppy is pregnant or close to giving birth, look for a swollen, darkened belly, which indicates the presence of developing fry. Additionally, you may observe a gravid spot near the rear of her abdomen that appears darker as she gets closer to giving birth. If she is hiding more than usual or exhibiting changes in behavior, these can also be signs that she is preparing to give birth.
