Kissing Gourami Species: Your Ultimate Guide To Their Unique Behavior

Written ByHoward Parker

Have you ever walked past an aquarium and seen two fish locked in a gentle, endearing “kiss”? It’s a captivating sight, and it’s the signature move of the one and only Kissing Gourami. It’s easy to assume this is a sign of affection, a sweet moment between two aquatic pals. But what if I told you that pucker-up isn’t about love at all?

That’s right. The world of the kissing gourami species is more complex and fascinating than it first appears. These fish are more than just a cute behavior; they are large, active, and full of personality, but they come with specific needs that many beginners overlook, leading to common problems down the road.

Don’t worry, though! You’ve come to the right place. We promise this complete kissing gourami species care guide will demystify their behavior and give you the confidence to raise these incredible fish successfully. You’ll learn the secrets behind their “kiss,” how to set up the perfect tank, and what it takes to keep them thriving for years to come.

Let’s dive in and uncover the truth behind those famous lips!

Unpacking the “Kiss”: What This Unique Behavior Really Means

Let’s get the biggest question out of the way first. That famous “kiss” is actually a form of sparring, not affection. When you see two Kissing Gouramis locking lips, they are testing each other’s strength and establishing dominance within the tank’s social hierarchy.

Think of it as an arm-wrestling match for fish. They use their thick, fleshy lips to push and shove, with the winner claiming higher status. This is most common between two males but can happen with any pairing. It’s a natural, instinctual behavior you don’t need to stop unless one fish is consistently bullying the other to the point of injury.

They also use their unique mouths for another important task: eating! Their lips are lined with tiny, rasping teeth, perfect for scraping algae and microorganisms off rocks, plants, and glass. So, while they aren’t kissing for love, their mouths are a critical and multi-purpose tool.

Meet the Kissing Gourami Species: Types and Varieties

While scientifically known as Helostoma temminckii, you’ll find a few different variations in the aquarium trade. Understanding them is key to making an informed choice for your tank.

The Classic Green (or Silver) Kissing Gourami

This is the wild-type coloration. These fish have a silvery-green, slightly iridescent body. They are robust, hardy, and showcase the most natural appearance of the species. They are the most common variety you will encounter.

The Pink (or Leucistic) Kissing Gourami

This is the most popular variety in the hobby. It’s not a true albino but a leucistic form, meaning it lacks pigment, resulting in a creamy pink or white body with normal-colored eyes. Their care requirements are identical to their green counterparts, but their bright color makes them a stunning centerpiece fish.

A Note on “Balloon” Kissing Gouramis

You might occasionally see a “Balloon” or “Dwarf” Kissing Gourami. These fish have been selectively bred for a compressed, rounded body shape. We at Aquifarm strongly advise against purchasing them. This genetic manipulation often leads to a host of internal health problems and a significantly shortened lifespan. Opting for a standard-bodied fish is one of the most important eco-friendly kissing gourami species best practices you can follow.

Setting Up the Perfect Home: A Kissing Gourami Species Guide to Tank Setup

This is where many fishkeepers make their first mistake. Those tiny 2-inch fish at the store grow up! Providing the right environment from the start is the secret to a happy, healthy gourami. This is the most crucial part of our kissing gourami species guide.

Tank Size: Go Big or Go Home

Kissing Gouramis can reach an impressive 10-12 inches (30 cm) in a home aquarium. They are active swimmers and need space to roam and establish territories.

  • Minimum Tank Size for One: 55 gallons (208 liters)
  • Minimum Tank Size for a Pair/Group: 75 gallons (284 liters) or more

A larger tank is always better. It helps dilute waste, provides more swimming space, and reduces aggression by allowing fish to have their own zones.

Water Parameters

The good news is that these fish are incredibly hardy! They are tolerant of a wide range of conditions, making them great for beginners who are still learning to maintain stable water. Don’t worry—these fish are perfect for beginners who are ready for a larger tank!

  • Temperature: 72-82°F (22-28°C)
  • pH: 6.0-8.0
  • Hardness: 5-20 dGH

Like all gouramis, they have a labyrinth organ, which allows them to breathe atmospheric air directly from the surface. This is a fascinating adaptation from their native, often oxygen-poor habitats. Always leave a few inches of space between the water surface and the tank lid to allow them access to air.

Filtration and Substrate

A powerful filter is a must, as large fish produce a lot of waste. A canister filter or a large hang-on-back (HOB) filter is an excellent choice. Aim for a moderate flow; they aren’t fans of strong currents.

For substrate, sand or smooth gravel works perfectly. They spend time grazing near the bottom, so avoid any sharp or abrasive materials that could injure their delicate mouths.

Decor and Plants

Decorations serve two purposes: aesthetics and security. Provide plenty of hiding spots using driftwood, smooth rocks, and caves. This helps break lines of sight and gives less dominant fish a place to retreat.

When it comes to plants, choose sturdy, hardy varieties. Kissing Gouramis are notorious grazers and may nibble on or uproot delicate plants. Great choices include:

  • Java Fern
  • Anubias
  • Amazon Swords
  • Vallisneria

Diet and Nutrition: What Do Kissing Gouramis Eat?

In the wild, Kissing Gouramis are “microphagous,” meaning they feed on tiny organisms like algae, plankton, and aufwuchs (the biofilm on surfaces). In the aquarium, they are easy-to-please omnivores.

A balanced diet is key to their health and vibrancy. Here are some of the benefits of kissing gourami species‘ varied diet:

  1. High-Quality Flakes or Pellets: This should be the staple of their diet. Choose a formula rich in vegetable matter, like a spirulina-based flake.
  2. Blanched Vegetables: They absolutely love veggies! Offer them blanched zucchini, cucumber, shelled peas, or spinach a few times a week. This mimics their natural grazing behavior.
  3. Frozen or Live Foods: Supplement their diet with protein-rich treats like brine shrimp, daphnia, or bloodworms. This helps promote growth and vitality.

Feed them once or twice a day, offering only what they can consume in a couple of minutes to avoid overfeeding and polluting the water.

Choosing the Right Tank Mates: Friends and Foes

Kissing Gouramis are often labeled as “semi-aggressive,” and this is where careful planning is essential. They are generally peaceful when young but can become territorial and pushy as they mature and grow. Their large size alone can be intimidating to smaller, more timid fish.

Good Tank Mates

The best tank mates are other large, robust, and relatively peaceful fish that can hold their own. Avoid anything small enough to be eaten or too timid to compete for food.

  • Other Large Gouramis: Pearl or Gold Gouramis (in a very large tank)
  • Larger Characins: Congo Tetras, Silver Dollars
  • Peaceful Cichlids: Severums, Angelfish (with caution, monitor behavior)
  • Catfish: Pictus Catfish, larger Corydoras species, Plecos
  • Loaches: Clown Loaches, Yoyo Loaches

Fish to Avoid

Steer clear of fin-nippers, very small fish, and slow-moving fish with long, flowing fins.

  • Small Tetras and Rasboras: They will likely be seen as food.
  • Guppies and Endlers: Too small and easily bullied.
  • Bettas: A very poor match due to potential aggression and fin-nipping.
  • Aggressive Cichlids: Avoid pairing with highly aggressive species like Jack Dempseys or Oscars.

Common Problems with Kissing Gourami Species (And How to Solve Them)

Even with the best care, you might run into issues. Here are some common problems with kissing gourami species and our top tips for handling them.

Aggression and Bullying

Problem: One gourami is constantly chasing or “kissing” another, preventing it from eating or causing visible stress.

Solution: Ensure the tank is large enough (75+ gallons) with plenty of decor to break sightlines. A “dither fish” school (like large, fast-moving tetras) can sometimes help distract the aggressor. If the bullying is severe, you may need to re-home one of the fish.

Ich (White Spot Disease)

Problem: You see small, salt-like white spots on the fish’s body and fins. The fish may be scratching against objects.

Solution: Ich is a common parasitic infection. Slowly raise the tank temperature to 82-84°F (28-29°C) to speed up the parasite’s life cycle and treat the tank with a commercial ich medication according to the instructions. Perform regular water changes during treatment.

Bloat

Problem: The fish’s abdomen is visibly swollen, and it may have trouble swimming.

Solution: Bloat is often caused by overfeeding or a poor diet. Fast the fish for 2-3 days, then offer a blanched, deshelled pea, which can help clear its digestive system. Afterward, re-evaluate its diet to include more high-fiber vegetable matter.

Sustainable and Eco-Friendly Kissing Gourami Species Practices

Being a responsible aquarist means thinking about our impact. Following sustainable kissing gourami species practices helps protect both the fish and the environment.

First, always source your fish from reputable breeders or stores. This ensures they are healthy and have not been collected from the wild using destructive methods. As mentioned earlier, avoiding genetically modified “balloon” varieties is a key part of ethical fishkeeping.

Second, never release aquarium fish into the wild. Kissing Gouramis are a hardy, adaptable species that could become invasive in non-native waterways, disrupting local ecosystems. If you can no longer care for your fish, contact a local fish store, an aquarium club, or another hobbyist to re-home it responsibly.

Frequently Asked Questions About Kissing Gourami Species

How big do kissing gouramis actually get?

In a properly sized home aquarium, they will realistically reach 10 to 12 inches (25-30 cm). Do not believe claims that they will “stay small” in a small tank; this only stunts their growth and leads to severe health issues and a shortened life.

Are kissing gouramis good for a community tank?

They can be, but only in the right community tank. It must be large (75+ gallons) and stocked with other large, semi-aggressive, or robust fish that won’t be bullied or eaten. They are not suitable for a typical peaceful community tank with small fish like neon tetras or guppies.

Why is my kissing gourami not “kissing”?

That’s perfectly normal! The “kissing” behavior is for establishing dominance, so if your gourami is alone or in a stable, established social group, you may rarely or never see it. A lack of kissing is often a sign of a peaceful tank.

Can I keep just one kissing gourami?

Yes, you can. While they can be kept in groups, they do perfectly well on their own. Keeping a single Kissing Gourami is often the best way to avoid the territorial aggression that can arise between two individuals.
