What determines Guppy color?
Genes: Genetics is the first and foremost factor that determines your guppy color. The faster your guppy grows, the sooner it will start gaining color. If you give your guppy live food, like baby brine shrimp or micro-worms, it will gain color faster than if you feed only veggies and flaked commercial food.
What causes such dramatic Guppy color variation?
The color patterns of male guppies are influenced by both sexual and natural selection (Endler 1978, 1983). Sexual selection (female mate choice) often (although not always) favors more colorful males (Houde 1987; Endler and Houde 1995; Brooks and Endler 2001).
Why do female guppies prefer brightly colored males?
Mate-choice experiments showed that females prefer colorful males as mates, but prefer bolder males irrespective of their coloration when given the opportunity to observe their behavior toward a potential fish predator.
What is the guppy experiment?
Endler transferred predatory fish to the regions with brightly colored male guppies, selection acted rapidly to produce a population of duller males. This demonstrates that persistent variation within a population provides the raw material for rapid evolution when environmental conditions change.
Why do guppies have spots?
The orange patches on male guppies are made up of two pigments: carotenoids (which they ingest in their diets and are yellow) and drosopterins (which are red and which their bodies produce). Plants produce carotenoids, but animals generally cannot; guppies obtain most of their carotenoids from algae.
Are guppies the same as Endlers?
Endlers are different from other guppy species in many ways. The body compositions are different to begin with, like the tail – an endler’s tail is composed of two little smaller fins, while the tail of a fancy guppy is much wider and richer in color. Often, the color distribution on their bodies is also different.
Can Endlers mate with guppies?
Yes, as you have found out first hand, guppies and endlers will cross and produce offspring. The offspring are not sterile and can be used to develop more guppy/endler varieties. Because of this, the Endler’s Livebearer is not its own species, and is actually just a unique guppy variant.

At what age do Guppies reproduce?
Females of matching body sizes tend to produce more numerous but smaller-sized offspring in high-predation conditions. Female guppies first produce offspring at 10–20 weeks of age, and they continue to reproduce until 20–34 months of age. Male guppies mature in 7 weeks or less.
What do guppies look like when mating?
Male guppies have a gonopodium. This looks like a stick and can be found at the anus of the male guppy fish. After the mating ritual, the male guppy will turn to the side, will point its gonopodium forward and will tap the female for 1-2 seconds. This time is enough to pass the sperm and fertilize the female.
Why do male guppies chasing pregnant female guppies?
During mating season, male guppies either attract females with their brightly-colored bodies or harass smaller females into mating by nipping and chasing them. Guppies, which constantly move between social groups in the water, form female pairs that help them improve foraging and protect them from predators.
