Swimming in Harmony: Guppy Tankmates That Get Along

Have you ever watched your guppies swimming and wished they could get along a bit better? Sure, they might look like complete harmony as the peaceful colors move gracefully in perfect circles, but if you’ve been trying to keep more than one species of fish in the same tank, you know that it isn’t always smooth sailing.

With the right tank mates for your guppies, however, having them swim together can be stress-free and beautiful.

Trying to figure out which fishes will play nice with each other can often feel perplexing — that is why we’ve compiled this article so that all aspiring aquarists can make sure their beloved pets are living in ultimate harmony.

Understanding the Guppy Fish

Guppy fish, also known as millionfish, are small freshwater fish native to South America.

They have vibrant colors and unique tails.

Aquarium enthusiasts love guppies for their hardiness and ease of care.

To keep guppies healthy, their behavior and preferences must be understood.

Guppies are social and do best in groups.

A minimum of three guppies – equal numbers of males and females – is ideal.

They will swim and play together, bringing life to the aquarium.

Choose tankmates carefully.

Guppies are peaceful, but certain species may be aggressive or pose a threat.

Stay away from fin-nippers and large predators.

Good choices for tankmates are tetras, mollies, platies, swordtails, danios, and cory catfish.

Male guppies may become territorial.

Give them hiding spots and plants.

This will create distinct territories and prevent aggression.

Choosing Suitable Tankmates for Guppies

Choosing the right tankmates for guppies is essential.

Here are some points to consider:

  • Size: Pick tankmates that are similar size to guppies, so that there is no aggressive behavior.
  • Temperature: Choose tankmates that can handle the same temperature range that guppies prefer.
  • Feeding: Choose tankmates with compatible feeding habits, to avoid any competition or overfeeding.
  • Social behavior: Guppies are social, so choose tankmates that are peaceful and non-predatory.
  • Space utilization: Pick tankmates that use different areas of the tank, so that the space is used efficiently.
  • Species compatibility: Make sure that the chosen tankmates have a good reputation for living with guppies.

Also, it is important to pick species known for their friendly nature, like platies or dwarf corydoras.

To ensure peaceful coexistence in the aquarium, avoid aggressive fish like bettas or bigger fish.

Factors to Consider When Selecting Tankmates

Guppies need compatible tankmates.

Pick fish with same temperaments and activity.

Consider size of tank and space for everyone.

Make sure all have same diet.

Look out for aggression or territorial behavior.

This way, you’ll create a peaceful and thriving tank.

1 – Water Parameters & Temperament

When selecting tankmates for guppies, it’s important to consider water parameters and temperament.

Guppies need temperatures between 72°F and 82°F, with a pH level of 6.8 to 7.8.

Plus, they need a habitat that mimics their natural environment.

Guppies are usually peaceful and sociable.

But, male guppies can be territorial and aggressive towards each other.

To reduce conflicts, a higher ratio of females to males is recommended.

Guppies generally get along with other fish like platies, mollies, and swordtails.

This is because they share the same water requirements and temperaments.

Bottom-dwellers like corydoras or plecos can also help make a balanced ecosystem.

Aggressive or larger fish should be avoided as tankmates, because they may harm guppies.

Fin nippers like tiger barbs or serpae tetras should also be kept away, as they nip at other fish’s fins.

2 – Size Compatibility

Size compatibility is key for guppy tankmates.

These bright fish do great in communities, but their small size makes them vulnerable to bigger, more aggressive species.

So it’s important to pick tankmates of similar size for harmony.

When adding new fish to a guppy tank, consider their size.

Guppies are usually around 2 inches, which is small compared to other aquarium fish.

This helps avoid any predation of the guppies.

Sometimes species will tolerate smaller mates, but they can become territorial as they grow and may be a threat.

Larger fish see the small guppies as prey or resource competitors.

This causes stress and aggression, affecting all inhabitants.

Also, large tankmates can compete with guppies for food.

This can lead to malnutrition or starvation if not watched closely.

Plus, larger fish produce more waste, potentially raising ammonia levels if not managed by water changes and filtration.

Fish to Avoid Keeping with Guppies

Guppies should not be mixed with certain fish species. Three types to avoid:

  • Aggressive Fish: Bettas, cichlids, and tiger barbs can be bullies and harm guppies.
  • Fin-Nipping Fish: Tiger barbs and mollies like to nip guppy fins. This can cause stress and injury.
  • Large Predatory Fish: Guppies should not be kept with big predators that view them as prey. Examples: angelfish, Oscars, and large catfish.

For a harmonious aquarium, think about these fish when choosing tankmates for guppies.

Creating a Harmonious Community Tank

  • Creating a serene community tank for your guppies is essential for their health.
  • Choose fish that get along, like tetras, platies, mollies, and dwarf corydoras catfish.
  • Provide hiding spots with plants, rocks, driftwood, and decorations.
  • Proper feeding is vital too. Give a varied diet suitable for each species.
  • Monitor feeding to prevent disputes over food.
  • By following these steps, you can make a peaceful and flourishing home for your fishy friends.


To get the most out of your guppy tankmates, it is important to know what kind of dynamics you are bringing into the tank.

That way, you can prevent any potential issues that could arise and keep everyone happy and swimming in harmony for years to come.

Hopefully this article has given you some insight on how to choose compatible fish for your aquarium.

Whether you stick with one kind or explore a variety of different peaceful and less aggressive species, there are plenty of fish options that will provide hours of encouragement and entertainment.

So why not give your guppies some tankmates to share their journey? And enjoy watching them swim in beauty and harmony.
