Determining whether a fish is pregnant can be crucial for maintaining a healthy aquarium and ensuring successful breeding. Pregnancy in fish, also known as gravidity, is characterized by several noticeable signs and behaviors.
One of the most prominent indicators is a visibly swollen abdomen. As the eggs develop inside the female fish, her belly will expand, often becoming noticeably round or elongated. Additionally, the gravid spot, a small, dark area near the anal fin, will become more pronounced and darker in color.
