Creating a vibrant and harmonious aquarium is an art that involves carefully selecting species that can live together in peace. Guppies, with their flamboyant colors and lively demeanor, are a favorite among aquarists for a community tank. However, ensuring these beautiful creatures thrive involves more than just meeting their basic needs; it’s about selecting good fish with guppies that share similar water conditions, dietary habits, and temperaments. This guide aims to highlight the key considerations and provide examples of suitable companions to help you create a thriving aquatic community.

Appearance and Behavior

Guppies, also known as Poecilia reticulata, are one of the most popular freshwater aquarium fish, beloved for their vibrant colors, dynamic behavior, and ease of care. Here’s a detailed look into the appearance and behavior of guppies.


Guppies are small, colorful fish, typically ranging from 1.5 to 2.5 inches (4-6,5 cm) in length. They exhibit a remarkable variety of colors, patterns, and fin shapes, which have been extensively diversified through selective breeding. The wild-type guppies tend to have more subdued colors, primarily in shades of gray and silver with some color spots, whereas domesticated varieties can display a wide spectrum of colors, including red, blue, green, yellow, orange, and even metallic hues.

Male guppies are especially known for their showy tails and dorsal fins, which can come in various shapes like the fan, delta, lyre, spear, and round. These fins are often adorned with intricate patterns, including spots, stripes, and swirls. Females are larger than males but less colorful and have shorter fins.


Guppies are known for their lively and sociable behavior. They are schooling fish and thrive in groups, showing more vibrant colors and active behaviors when kept with conspecifics. Their social nature makes them excellent candidates for community aquariums, where they can interact with other peaceful fish species.

One of the most notable behaviors of guppies is their breeding activity. Guppies are livebearers, meaning they give birth to free-swimming fry rather than laying eggs. Males are often seen displaying their fins and performing elaborate dances to attract females. After a gestation period of about 21 to 30 days, a female can give birth to a brood of 20 to 50 fry, although larger broods are not uncommon.

Guppies are also known for their adaptability, capable of surviving in a wide range of environmental conditions. This adaptability extends to their diet, as they are omnivorous and will eat a variety of foods, including flake, live, and frozen foods, as well as algae and plant matter.

Good Fish with Guppies

When selecting tank mates for guppies, it’s crucial to consider several factors to ensure a harmonious and healthy aquarium environment. Here are key considerations followed by examples of good tank mates:

Key Considerations

  • Temperament: Choose peaceful and non-aggressive species that won’t bully or stress your guppies. Aggressive fish can harm guppies by nipping at their fins or outcompeting them for food.
  • Size: Select fish that are similar in size to guppies. Larger fish might view guppies as prey, especially the smaller, more vibrantly colored males.
  • Water Conditions: Ensure that the chosen tank mates thrive in the same water conditions as guppies. Guppies prefer water with a pH of around 7.0 to 8.0, temperatures between 72°F to 82°F (22°C to 28°C), and moderate hardness.
  • Dietary Needs: Opt for fish with similar dietary preferences to make feeding straightforward. Guppies are omnivores and do well with a varied diet, so compatible tank mates should have no issues with standard flake, frozen, or live foods.
  • Activity Level: Guppies are active and playful. Fish with a similar activity level are preferable, as too much disparity can stress either species.

Examples of Good Tank Mates

Good fish with guppies include:

  • Corydoras Catfish: Peaceful bottom-dwellers that keep to themselves. They help clean the tank by eating leftover food from the substrate.
  • Neon Tetras: Small, peaceful fish that prefer to school. Their vibrant blue and red coloring complement the guppies’ colors without outshining them.
  • Mollies and Platies: These fish are similar in care requirements and temperament to guppies, making them excellent companions. They come in various colors and can add diversity to the tank.
  • Harlequin Rasboras: Known for their peaceful nature and beautiful silver bodies with black patches. They enjoy similar water conditions and are great for adding activity to the middle levels of the tank.
  • Cherry Shrimp and Ghost Shrimp: While not fish, these invertebrates are great tank mates for guppies. They help keep the tank clean by eating algae and leftover food, and their small size and peaceful nature make them suitable companions.
  • Dwarf Gouramis: Peaceful, beautiful fish that can add color and diversity to the tank. Choose the smaller, more peaceful varieties to ensure compatibility.

When introducing any new tank mates, it’s essential to monitor the aquarium closely for the first few days to ensure all fish are getting along and that there are no signs of stress or aggression. Proper tank management, including regular maintenance and water quality checks, will help keep all inhabitants healthy and happy.


In the quest to build a peaceful and visually stunning aquarium, choosing the right tank mates for your guppies is crucial. Remember, good fish with guppies are those that complement their lifestyle without outcompeting or endangering them. By considering factors such as size, temperament, dietary needs, and water conditions, you can create a harmonious environment where all species can flourish. Whether you opt for the playful neon tetras, the diligent Corydoras catfish, or the peaceful dwarf gouramis, ensuring compatibility will lead to a healthier, happier aquatic community. Keep these guidelines in mind, and you’ll be well on your way to creating an aquarium that’s both beautiful to behold and a safe haven for its inhabitants.
