Is the gravid spot on both sides of guppy?

The gravid spot, also known as the gestation or pregnancy spot, is a dark, triangular-shaped marking that appears on the lower abdomen of female guppies when they are pregnant. It is caused by the development of the eggs within the female's body and serves as an indication of her reproductive status. The gravid spot is typically located towards the back of the female's belly and becomes more prominent and darker as the pregnancy progresses. It is a common misconception that the gravid spot appears on both sides of the guppy. However, it is typically only visible on one side of the female, usually on the side facing upwards or towards the viewer when she is swimming horizontally.
