Determining whether a fish is pregnant can be crucial for responsible fishkeeping and breeding. Pregnancy in fish, also known as gravidity, is characterized by several noticeable signs and behaviors.
The most evident sign of pregnancy in fish is a swollen or distended abdomen. As the eggs develop inside the female fish, her belly will become noticeably larger and rounder. Additionally, the gravid spot, a dark or pigmented area near the anal fin, will become more prominent.
