Gourami With Other Fish – Your Ultimate Guide To Peaceful Tank Mates

Written ByHoward Parker

So, you’ve been captivated by the graceful fins and curious personality of the gourami. It’s easy to see why! These beautiful fish can be the shimmering centerpiece of any freshwater aquarium. But a common question stops many aquarists in their tracks: “Can I actually keep a gourami with other fish without turning my peaceful tank into an underwater battlefield?”

I get it. You’ve heard stories. Some say gouramis are peaceful, while others label them as bullies. The truth? It’s a bit of both, but don’t let that discourage you. I promise that with the right knowledge and a little planning, you can absolutely create a stunning, harmonious community tank with a gourami at its heart.

In this complete guide, we’re going to dive deep into everything you need to know. We’ll explore the different gourami personalities, uncover the best (and worst) tank mates, and share expert tips for setting up your aquarium for success. Let’s build that dream tank together!

Understanding the Gourami Personality: Not All Are Created Equal

Before we can talk about tank mates, we need to understand the fish itself. Gouramis belong to a group of fish called Anabantids, or labyrinth fish. This means they have a special “labyrinth organ” that allows them to breathe atmospheric air directly from the surface—it’s why you’ll often see them taking a gulp of air!

This unique trait is cool, but it’s their temperament that we need to focus on. Gourami personalities can range from incredibly shy and peaceful to bold and semi-aggressive. Choosing the right species is the first and most important step in this gourami with other fish guide.

The Gentle Giants: Peaceful Gourami Species

If you’re a beginner or have an existing peaceful community tank, these are the gouramis you should be looking for. They are known for their gentle nature and are far less likely to cause trouble.

  • Honey Gourami (Trichogaster chuna): These small, golden-hued fish are wonderfully peaceful. They are a bit shy, so they appreciate a well-planted tank where they can feel secure. They are an excellent choice for smaller community setups (20 gallons and up).
  • Pearl Gourami (Trichopodus leerii): Often considered one of the most beautiful and peaceful of the larger gouramis. Their pearly, iridescent bodies are stunning. They are relatively hardy and do well in tanks of 30 gallons or more with other peaceful fish.
  • Dwarf Gourami (Trichogaster lalius): Immensely popular for their vibrant colors, Dwarf Gouramis are generally peaceful but can be a bit territorial with their own kind, especially males. Keeping a single one or a mated pair is often the best approach in a community tank.

The “Big Personalities”: Semi-Aggressive Gourami Species

These species can still be kept in community tanks, but they require more careful planning, larger tanks, and very specific tank mates. They are not recommended for first-time gourami owners.

  • Three Spot Gourami (Trichopodus trichopterus): This is the species that gives gouramis their “bully” reputation. This group includes the popular Blue, Gold, and Opaline color morphs. They can be territorial and aggressive, especially as they mature. A large tank (50+ gallons) with robust tank mates is a must.
  • Kissing Gourami (Helostoma temminckii): Their “kissing” behavior isn’t a sign of affection—it’s a form of sparring for dominance! They can grow quite large and are best kept with other large, semi-aggressive fish in a very spacious aquarium.

Your Complete Gourami with Other Fish Compatibility Guide

Alright, you’ve picked your gourami species. Now for the fun part: choosing their friends! The key is to select fish that won’t compete for the same space, won’t nip at the gourami’s long fins, and won’t be intimidated by their presence. This is one of the most important gourami with other fish tips I can give you.

The Best Tank Mates for Most Gouramis

These fish are generally safe bets for peaceful gourami species like the Honey, Pearl, and Dwarf Gourami. They occupy different levels of the tank and have a calm disposition.

  1. Corydoras Catfish: These adorable armored catfish are the perfect bottom-dwellers. They are peaceful, busy, and will stay completely out of your gourami’s way, which typically hangs out in the mid-to-top levels of the tank.
  2. Peaceful Tetras: Schooling fish like Neon Tetras, Cardinal Tetras, Rummy Nose Tetras, and Ember Tetras are excellent choices. Their schooling behavior is beautiful to watch, and they are too fast and small to be seen as a threat. Always keep them in groups of 6 or more to make them feel secure.
  3. Harlequin Rasboras: A classic and reliable choice. These peaceful, schooling fish have a calm temperament and add a lovely splash of color and activity to the mid-water column.
  4. Kuhli Loaches: These quirky, eel-like bottom dwellers are fascinating to watch. They are nocturnal and shy, meaning they will have very little interaction with your gourami.
  5. Bristlenose Pleco: If you need an algae-eater, the Bristlenose Pleco is a fantastic option. They are peaceful and won’t grow to the monstrous sizes of some other pleco species.

Fish to Approach with Caution

These pairings can work, but you need to be observant and have a backup plan. Success often depends on individual fish personalities and tank setup.

  • Livebearers (Guppies, Mollies, Platies): While generally peaceful, the long, flowing fins of some fancy guppies can be a target for a curious gourami. Conversely, some mollies can be boisterous and may stress out a shyer gourami.
  • Other Anabantids (especially Bettas): This is a risky combination. Both gouramis and bettas are labyrinth fish and can be highly territorial towards similar-looking species. It’s generally best to avoid this pairing.
  • Certain Barbs: While Cherry Barbs are usually peaceful enough, notorious fin-nippers like Tiger Barbs are a definite no. They will relentlessly harass your gourami.

Tank Mates to Absolutely Avoid

Do not attempt these pairings. It will almost certainly end in stress, injury, or death for one of the fish involved.

  • Large, Aggressive Cichlids: Fish like Oscars, Jack Dempseys, or African Cichlids are far too aggressive and will bully or kill a gourami.
  • Freshwater “Sharks”: Species like the Red Tail Shark or Rainbow Shark are notoriously territorial and will likely harass a gourami to no end.
  • Goldfish: They have completely different temperature and care requirements. Goldfish are cold-water fish, while gouramis are tropical.

Setting Up Your Tank for Success: Best Practices for Harmony

A successful community tank is about more than just picking the right fish. The environment you create plays a huge role in keeping the peace. Following these gourami with other fish best practices will set you up for a thriving aquarium.

Tank Size Matters (A Lot!)

Don’t overcrowd your fish! A cramped tank is a recipe for stress and aggression. A larger tank gives everyone their own space.

  • For small species like Honey or Dwarf Gouramis, a 20-gallon tank is a good starting point for a community setup.
  • For medium species like Pearl Gouramis, you should be looking at a minimum of 30-40 gallons.
  • For semi-aggressive species like the Three Spot Gourami, a 55-gallon tank or larger is necessary to curb their territorial instincts.

Creating a “Broken” Line of Sight

This is a pro-level tip that makes a world of difference. A tank with lots of open space allows a dominant fish to see and control the entire area. By adding decorations, you break up the tank into smaller territories.

Use plenty of live or silk plants, driftwood, and rockwork to create visual barriers. This allows fish to escape each other’s view, which dramatically reduces chasing and aggression. It makes a shy fish feel more secure and a territorial fish less stressed.

Common Problems with Gourami with Other Fish (And How to Fix Them!)

Even with the best planning, issues can sometimes arise. Don’t panic! Here’s a quick troubleshooting guide for the most common problems you might encounter.

My Gourami is Chasing Other Fish!

First, identify the trigger. Is it a new addition? Is the tank too small? Often, this is a territorial display. Try rearranging the decorations to “reset” the established territories. If the problem persists, ensure there are enough hiding spots for the other fish to retreat to.

My Other Fish are Picking on My Gourami!

This is usually due to a poor tank mate choice, like a fin-nipping barb. The long, delicate ventral fins of a gourami are an irresistible target. The only real solution here is to separate the fish by re-homing the aggressor to a different tank.

Signs of Stress to Watch For

A happy fish is an active and colorful fish. Be on the lookout for signs of stress, which can indicate a problem with tank dynamics or water quality.

  • Hiding constantly and refusing to come out
  • Clamped fins (held tightly against the body)
  • Dull or faded colors
  • Refusing to eat

If you see these signs, your first step should always be to test your water parameters (ammonia, nitrite, nitrate). If the water is fine, observe the tank closely to identify any bullying that might be happening.

A Note on Sustainable and Eco-Friendly Gourami Keeping

As responsible aquarists, we have a role to play in protecting the natural world. Embracing sustainable gourami with other fish practices is easier than you think and contributes to the health of our hobby and the planet.

Whenever possible, choose captive-bred fish over wild-caught specimens. This reduces pressure on wild populations and their delicate ecosystems. Additionally, incorporating live plants into your aquarium is a fantastic eco-friendly choice. They act as natural filters, oxygenate the water, and provide shelter, creating a more balanced and self-sufficient environment.

Frequently Asked Questions About Keeping Gourami with Other Fish

Can I keep a gourami with a betta fish?

This is generally not recommended. Both are territorial labyrinth fish and are very likely to see each other as rivals, leading to constant fighting and stress.

How many gouramis can I keep together?

For most species, it’s best to keep only one male per tank to avoid territorial aggression. You can often keep a single male, a mated pair, or a group of females (for species like the Pearl Gourami). Avoid keeping two males together unless the tank is very large and heavily decorated.

What is the most peaceful type of gourami for a community tank?

The Honey Gourami is widely considered the most peaceful and beginner-friendly option. They are shy, small, and get along with a wide variety of other peaceful fish.

Do gouramis need to be in groups?

Unlike schooling fish, gouramis do not need to be in groups to feel secure. Most are perfectly happy being the only gourami in the tank, which often helps prevent any intra-species aggression.

Your Journey to a Beautiful Community Tank

Creating a peaceful aquarium with gourami with other fish is a truly rewarding experience. It’s about more than just adding water and fish; it’s about building a balanced, thriving little ecosystem right in your own home.

Remember the keys to success: choose the right gourami species for your experience level, select compatible and peaceful tank mates, and provide a spacious, well-decorated environment that makes everyone feel safe and secure.

You now have the knowledge and the expert tips to move forward with confidence. Go create that beautiful, bustling aquarium you’ve been dreaming of. Happy fishkeeping!
