As a guppy owner, it’s essential to understand the factors that influence the color development of your baby guppy fish.

In this ultimate blog post, we will delve deeper into the topic and provide all the information you need about when do guppies get their color. So, let’s dive in to help your fish get colors sooner!

When Do Baby Guppies Get Their Color?

When do guppy babies get their color? Baby guppies are born without coloration, and their initial appearance is plain compared to their adult counterparts. “Baby guppies typically start to develop their signature colors between the ages of 1 to 6 weeks old. 

While they may not appear particularly vibrant or striking at first glance, it is during this period that you can expect to see some coloration in your guppy fry.”

What Do Guppy Fry Eat

However, their colors and patterns emerge as they grow the sooner and mature. The timeline for guppy color development can vary based on several factors, including genetics, water chemistry, diet, and overall care provided.

Why Do Guppies Change Color?

Guppies, scientifically known as Poecilia reticulata, are colorful and vibrant freshwater fish that are widely sought after by aquarium enthusiasts. One intriguing aspect of guppies is their ability to change color. There are a few reasons why guppies exhibit color changes:

  • Genetic Factors: Guppy coloration is influenced by genetics. Different color genes determine the pigmentation patterns and hues displayed by individual guppies. Through selective breeding, breeders have developed various color strains, resulting in a wide range of color variations.
  • Environmental Factors: Changes in the fish’s environment, such as water quality, lighting, and tank decor, can impact their coloration. Guppies have chromatophores, special cells that contain pigments responsible for their color. Environmental factors can affect the activation and expression of these pigments, leading to temporary or permanent color changes.
  • Social Interaction and Mating Displays: Male guppies often display vibrant colors during courtship rituals to attract females. These color displays are a result of heightened hormone levels and are temporary. Once the mating display is over, the male guppy’s colors may return to their baseline.

It’s important to note that color changes in guppies can be influenced by a combination of genetic and environmental factors. These changes often add to the visual appeal and intrigue of keeping guppies in aquariums, making them a fascinating and dynamic species to observe.

Guppy Fry Color Stages Development Timeline

Guppy Fry Stage:

  • When baby guppies are first born, they are colorless or translucent, resembling tiny, delicate versions of their parents. At this early stage, they rely on their yolk sac for nourishment.
  • The fry stage lasts about 2-11 weeks, during which they focus on growing and developing their internal systems before showing any signs of color.

Start Getting Some Color:

  • After the fry stage, guppies start showing slight hints of color on their body and fins.
  • At around 2-3 months, some guppies may begin to develop faint coloration, which is when their hues gradually become visible.

Color Development Progression:

  • As guppies continue to grow, baby guppy colors become more pronounced and vibrant. The speed of color development may vary from one guppy to another, even among siblings.

Full-Color Transformation:

  • On average, guppies reach their full coloration at around 6-8 months.
  • By this time, the once-translucent fry has blossomed into dazzling adult guppies, displaying various colors and patterns that captivate fish enthusiasts.

What Determines When A Guppy Fish Gets Its Color?

When do guppy fry start to show color? A range of factors, including genetics, age, gender, and environmental conditions, determines the coloration of a guppy. Guppies can start getting their colors as early as a few weeks old, and juveniles usually develop their full coloration by the time they are three to four months old.

The environment in which a guppy is kept can play a crucial role in its color. Guppies kept in a well-maintained aquarium with clean water, proper filtration, and frequent water changes are likelier to display vibrant colors than those observed in suboptimal conditions.

The presence of live plants and hiding places in the tank can also help reduce stress levels in guppies, leading to more vibrant coloration.

The food source also plays a crucial role in determining the color of guppies. A varied diet that includes high-quality commercial foods, frozen or live foods, and even baby brine shrimp can help enhance guppies’ color.

Additionally, the byproducts of fish waste can contribute to the growth of algae and microorganisms in the tank, providing a natural food source for guppies and helping to enhance their coloration.

It’s worth noting that guppy fry will start to get their colors at around four to six weeks old, but it can take several months for their full coloration to develop. As with adult guppies, the quality of their environment and diet will also play a significant role in determining the color of guppy fry.

Factors Affecting Guppy Color Development

When do guppy fry get color? Several factors influence the color development of baby guppy fish:


Their genetic makeup primarily determines the coloration of guppies. Guppy breeders often select traits to enhance specific colors and patterns in their breeding programs.

Water Quality:

Giving your guppies fresh, clean water is crucial for healthy color development. Regular water changes and proper filtration ensure the water remains free of toxins and contaminants that could impact baby guppy colors.


A balanced and varied diet is essential for optimal color development. Feeding your guppies high-quality fish, including live and frozen foods like baby brine shrimp, enhances their color vibrancy.

Temperature and Environment:

Maintaining an appropriate temperature and environment in the guppy tank is vital for their overall health and color development. A stable and stress-free environment promotes better coloration.

Male vs. Female Guppy Coloration

Male and female guppies exhibit distinct color differences. Males are generally more colorful than females, with vibrant hues and intricate patterns. Their elaborate coloration serves as a means to attract potential mates during courtship displays.

On the other hand, female guppies tend to have more subdued colors, focusing on natural camouflage to protect themselves and their fry from predators.

Do Brighter Colors Indicate Healthier Guppies?

 Guppies are known for their colorful appearance, and many guppy breeders strive to breed guppies with vibrant colors. But do these bright colors indicate healthier guppies?

The answer is more complex. While male guppies are typically more colorful than their female counterparts, this does not necessarily mean they are healthier. 

The coloration of guppies can be influenced by various factors such as diet, genetics, and environmental conditions. Guppy breeders must focus on overall health indicators like activity level, finnage, and body condition rather than solely relying on bright colors.

Ultimately, a combination of vibrant colors and good health is what breeders should strive for when creating beautiful and healthy guppies. 

Why Are Male Guppies More Colorful Than Females?

Male guppies are more colorful than female fish because they have evolved to attract mates. Female guppies are generally drab in color, allowing them to blend in with their surroundings and reduce predation risk.

On the other hand, male guppies have vibrant colors and elaborate patterns to enhance their chances of reproduction. The bright coloration of male guppies results from sexual selection, where females prefer mates with more striking appearances.

This preference has caused male guppy fish to develop and display intense, eye-catching colors. The evolution of such bright colors in male guppies indicates their genetic quality and health, increasing their chances of successfully attracting a mate.

Do Guppies Change Color?

Guppies are known for their vibrant and eye-catching colors, but do they change color? The answer is yes and no. Guppies go through color changes, which are not dramatic or frequent. Guppies tend to exhibit color variations based on their age and surroundings.

As they grow older, guppies may experience a slight shift in their color patterns, with males typically becoming more vibrant to attract mates.

Additionally, guppies can change their color intensity depending on their environment. They can darken or lighten their hues to blend in with their surroundings, thus providing a protective camouflage against predators. So while guppies do undergo some color changes, it is not a drastic or constant process.

Can Guppies Lose Color? If So, Why?

Guppies are colorful freshwater fish species known for their vibrant hues. However, guppies can lose color over time. This phenomenon is more common among male guppies, as their colors are more pronounced than females.

There are several reasons why guppies may experience a loss of color. One factor is age, as older guppies may naturally fade in color as they age. Stress can also play a role in color loss, as environmental factors such as poor water conditions or overcrowding can cause guppies to lose their vibrant pigmentation.

In some cases, illness or disease can also result in a loss of color in guppies. Proper care, a balanced diet, and optimal living conditions can help maintain the vibrant baby guppy colors.
