How to Choose Guppy Tank Mates

Guppies are delightful and popular aquarium fish known for their vibrant colors and active personalities. Choosing the right tank mates for guppies is crucial to ensure a harmonious and thriving aquatic community. Here are the steps to help you select suitable guppy tank mates:

Step 1: Know Your Guppies

Before choosing tank mates, understand your guppies. Guppies are generally peaceful, but there can be variations in temperament among individual fish. Familiarize yourself with the specific guppy varieties you have, as fancy guppies may have more delicate fins compared to common guppies.

Step 2: Research Guppy Varieties

Different guppy varieties may have unique requirements and temperaments. Some well-known guppy varieties include common guppies, fancy guppies, and Endler’s Livebearers. Research the specific traits and needs of your guppy variety to help guide your tank mate choices.

Step 3: Consider Water Parameters

Water parameters, such as temperature, pH, and hardness, are critical for the well-being of your fish. Ensure that the tank mates you choose have similar water parameter preferences to your guppies. This minimizes stress and ensures all fish thrive.

Step 4: Determine Tank Size

The size of your aquarium is a significant factor in choosing tank mates. The larger the tank, the more room there is for different species. Generally, a 20-30-gallon tank is suitable for starting a guppy community, but larger tanks are ideal for more diversity and space for swimming.

Step 5: Compatibility with Guppies

Consider the specific needs and behaviors of these potential tank mates to ensure they are a good fit for your guppies.

Step 6: Behavior and Temperament

Select tank mates with compatible behavior and temperament. Avoid aggressive species or fin-nippers, as guppies, especially fancy varieties, can be vulnerable to bullying. Peaceful and community-oriented fish are usually a safer choice.

Step 7: Avoid Overcrowding

While it’s tempting to have a diverse community, avoid overcrowding your tank. Overcrowding can lead to stress, disease, and competition for resources. Calculate the appropriate number of fish based on your tank’s size and filtration capacity.

Step 8: Provide Hiding Places

Create an environment with hiding places, plants, and decorations to offer shelter and separation for different species. This helps reduce stress and provides a sense of security for all tank mates.

Step 9: Observe and Adjust

After introducing tank mates, closely monitor the interactions among your fish. Watch for signs of stress, aggression, or compatibility issues. Be prepared to make adjustments if necessary, which may include rehoming or isolating certain fish.

Minimum tank size for a freshwater aquarium with multiple species

The size of a tank required to house multiple species of fish largely depends on several factors, including the specific species you intend to keep, their size, behavior, and compatibility. However, as a general guideline, you can follow these tank size recommendations:

  1. Species Compatibility: Select fish and invertebrate species that are compatible in terms of water parameters, temperament, and dietary requirements. Research the specific species to ensure they can coexist peacefully.
  2. Fish Size: Consider the adult size of the fish species you plan to keep. Smaller fish typically require less space than larger ones. Ensure the tank can accommodate the largest species comfortably.
  3. Schooling Fish: Some species, like tetras and rasboras, are shoaling or schooling fish, which means they thrive in groups. A larger tank is necessary to accommodate these social behaviors.
  4. Territorial Fish: Some species are territorial and require adequate space to establish their territories. Cichlids are a classic example of territorial fish.
  5. Biological Load: Consider the biological load, which relates to the waste production and filtration needs of the fish. Multiple species mean a higher bio-load, which may require a more robust filtration system and larger tank.
  6. Aquascape and Hiding Places: Create an environment with adequate hiding places, plants, and decor to provide shelter and separation for different species.
  7. Aquarium Shape: The shape of the tank can also affect compatibility. Longer tanks provide more swimming space, which can be crucial for certain species.

As a general rule of thumb, a minimum tank size of 20-30 gallons (75-115 liters) is often recommended for starting a community tank with multiple compatible species. However, for a community tank with a variety of species, larger tanks, such as a 55-gallon (208-liter) or 75-gallon (284-liter) tank, are even better. For larger or more aggressive species, much larger tanks may be required.

It’s important to research the specific species you plan to keep and consider their individual needs when determining the appropriate tank size. Always prioritize the well-being and comfort of your aquatic pets, as overcrowded or undersized tanks can lead to stress, aggression, and health issues.


Selecting the right tankmates for your guppies is a key aspect of creating a thriving and visually captivating aquarium. This comprehensive list of over 50 compatible fish and invertebrate species provides you with a diverse range of options to choose from, catering to the needs and preferences of both beginner and experienced aquarists. By following the guidelines outlined in this guide, you can create a harmonious aquatic ecosystem that ensures the well-being and enjoyment of your guppies and their companions.
