Pursuing Genetic Purity in ‘Poecilia Parae’ Fish

Unlike most species, ‘poecilla parae’ have maintained a level of color purity unknown in most of the animal or human kingdom. The fish come in exactly five, genetically determined colors: red, yellow, blue, parae (clear with a black stripe), and immaculate (drab grey that mimics the color of immature females).

This is one complicated evolutionary story, so please listen up!

Immaculates Must Get Dirty

If ‘immaculate’ makes you think of the Virgin Mary and birth without a sexual romp, erase. We’re entering the rough and tumble world of males at war. Even immaculates have to play ball, in order to reproduce.

The immaculates may be divine right fish, but they are generally the smallest and hate violence. The yellows almost always defeat the immaculatas, stopping them from approaching females.

Complicating the sex habits of ‘poecillia parae’ is the fact that girl fishies prefer red and yellow fish, just as human women prefer a man in red. (Why then do women say they hate red lingerie, man’s favorite color? No wonder we confound men.)

Not Enough Good Red and Yellows

Guess what? Females prefer a red fish or yellow one, but they are in short supply and the rarest colors found in the ‘poecilia parae’ wild. Forget the fact that the girl fish are promiscuous as hell. Even if they were monogamous, there’s not enough red and yellow males to meet their sexual needs.
