Below Are Ways To Tell The Difference Between A Male and Female Guppy Fish

The Gravid Spot

This spot looks dark, found at the dorsal region, and close to the tail. Once you can locate this spot in a guppy fish, it means it is female because

male ones don’t have the gravid spot. This spot is more pronounced in a female that is pregnant, as it grows larger compared to when they are not pregnant.

The eyes of the fetus developing in the mother’s womb pressing against the belly formed the gravid spot. Once the fries are delivered, the blackspot starts becoming light until it fades away.

The Guppy Fins

There are various types of fins in fish generally, and guppies are not exempted. They have dorsal, caudal and anal fin.

i)  Dorsal Fin:

Close to the fish head is the dorsal fin. The sizes of the dorsal fin differ in both male and female guppy fish. Compared to the male, females have small and not too long dorsal fins while males have big fins. While swimming, make dorsal fins appear on the water, unlike the female dorsal fin.

  ii) Caudal Fin:

This is also called guppy’s tail fin. When you see a vast, colorful like the rainbow and prolonged kind of fin in guppies, just know they are males. Females have short and not too wide caudal fins.

iii) Guppy Anal fin:

You need to hold a guppy fish to see their anal fins; it is located below the tail. The significant difference between the anal fin of

male and female guppy fish is the shape. When you see a rectangular like shaped fin then that is a female guppy fish, while those that have pointed anal fins are the males.

The Guppy Fins

It is until the male gonopodium(anal fin) develops that is when can start to have intercourse by inserting their anal fin into female guppy’s anal vent. The female pregnancy occurs between 21 – 30 days, female guppies store semen (sperm) for years so that they can impregnate them self in  the future.

Don’t be disturbed if your fries lack anal fins because it will develop with time; it is used by the males to mate and impregnate the female guppy fish when it is matured.

adult male guppy fish for the first time. They have colors like orange, indigo, violet, spot, and different shades of stripes.
