Determining whether a guppy is pregnant is crucial for the well-being of both the mother fish and her fry. Guppy pregnancy lasts approximately 21 to 30 days, and there are several telltale signs to watch for to ascertain the condition.
One of the most noticeable signs of pregnancy in guppies is the development of a gravid spot. This dark, triangular-shaped area is located near the anal fin and becomes more prominent as the pregnancy progresses. The gravid spot is essentially a collection of developing eggs, and its size and darkness can provide an indication of the number and maturity of the fry.
