Written ByHoward Parker

Are you searching for a freshwater fish that’s both stunningly beautiful and full of personality? It can feel overwhelming trying to find a centerpiece fish that’s hardy enough for beginners but still captivating for seasoned keepers.

Well, your search is over. The magnificent blue gourami fish is one of the most rewarding and resilient fish you can welcome into your home aquarium. Don’t worry—these fish are perfect for beginners!

In this complete blue gourami fish care guide, we promise to walk you through everything you need to know to create a vibrant, peaceful aquatic haven. We’ll cover their ideal tank setup, diet, fascinating behaviors, and how to choose the perfect tank mates.

By the end, you’ll have all the expert tips you need to help your new aquatic friend not just survive, but truly thrive.

Meet the Blue Gourami: More Than Just a Pretty Face

Before we dive into the “how to blue gourami fish” specifics, let’s get to know this incredible species. The Blue Gourami (Trichopodus trichopterus) is also known by another name you’ll see in pet stores: the Three Spot Gourami.

Why “Three Spot”? They typically have two distinct dark spots along their body, and their eye acts as the third “spot.” It’s a fun little quirk! The fish sold as Blue Gouramis are simply a color morph of this species, selectively bred for their dazzling iridescent blue and turquoise hues.

One of their most fascinating features is their labyrinth organ. This special organ allows them to breathe atmospheric air directly from the surface! This is an adaptation from their native habitats in the slow-moving, oxygen-poor waters of Southeast Asia. You’ll often see them dart to the surface for a gulp of air, which is completely normal and captivating to watch.

Benefits of Blue Gourami Fish in Your Aquarium

Still on the fence? Here are a few reasons why this fish is a fantastic choice:

  • Hardiness: They are incredibly forgiving of beginner mistakes and can adapt to a range of water conditions.
  • Personality: Blue Gouramis are intelligent and inquisitive. They will learn to recognize you and may even greet you at the front of the tank!
  • Stunning Appearance: Their shimmering blue coloration makes them a true showstopper in any community tank.
  • Longevity: With proper care, these fish can live for 5 years or even longer, becoming a long-term companion.

Setting Up the Perfect Home: Your Blue Gourami Fish Tank Guide

Creating the right environment is the most critical step for a healthy fish. Think of yourself as an aquatic architect—your goal is to build a home where your gourami feels safe, comfortable, and stimulated. Here are the blueprints for success.

Tank Size Requirements

While you might see small juveniles in stores, these fish grow! A single Blue Gourami needs a minimum of a 20-gallon tank. For a pair or a community setup, a 30-gallon tank or larger is highly recommended.

A longer tank is better than a taller one, as it provides more horizontal swimming space and surface area for them to breathe. Overcrowding is a major source of stress and aggression, so always give them plenty of room to roam.

Ideal Water Parameters

As mentioned, Blue Gouramis are tough. However, to see their best colors and health, aim for stable water conditions. Here’s a simple checklist:

  • Temperature: 74-82°F (23-28°C)
  • pH Level: 6.0-8.0 (they are very adaptable, but a neutral 7.0 is a great target)
  • Hardness: 5-25 dGH
  • Filtration: A gentle filter is best. Labyrinth fish come from slow-moving waters, and a powerful filter output can stress them out. A sponge filter or a hang-on-back filter with an adjustable flow is perfect.

Always ensure your tank is fully cycled before adding your fish. This means establishing a healthy colony of beneficial bacteria to process harmful ammonia and nitrite. This is one of the most important blue gourami fish best practices for long-term health.

Creating a Natural Habitat: Plants & Decor

A barren tank is a stressful tank. Blue Gouramis love a well-planted aquarium with plenty of places to hide and explore. Live plants not only look beautiful but also help maintain water quality.

Great plant choices include Java Fern, Anubias, Hornwort, and Amazon Swords. Add some driftwood or smooth rocks to create caves and territories. This gives them a sense of security and helps reduce potential aggression by breaking up lines of sight.

What’s on the Menu? Feeding Your Blue Gourami for Optimal Health

Good news! Blue Gouramis are not picky eaters. They are omnivores, which means they enjoy a varied diet of both plant-based matter and protein. A balanced diet is key to their vibrant color and energy levels.

A high-quality tropical flake or pellet food should be their daily staple. Look for one with natural color-enhancing ingredients. To supplement this, offer them treats 2-3 times a week.

Healthy Treat Options:

  • Frozen Foods: Bloodworms, brine shrimp, and daphnia are excellent sources of protein.
  • Live Foods: If you’re up for it, they will eagerly hunt live brine shrimp or daphnia.
  • Vegetables: Blanched zucchini or shelled peas are a great source of fiber.

Feed them only what they can consume in about two minutes, once or twice a day. Overfeeding is one of the most common mistakes in the hobby and can lead to poor water quality and health problems.

Friends or Foes? Blue Gourami Temperament and Tank Mates

This is where many new owners run into trouble. While often sold as peaceful community fish, Blue Gouramis can have a semi-aggressive streak, especially the males. Understanding their temperament is crucial for a harmonious tank.

Understanding Gourami Aggression

Males can be territorial, particularly with other male gouramis or fish that look similar (long, flowing fins). Never keep two male Blue Gouramis in a tank smaller than 55 gallons, and even then, make sure it’s heavily planted to provide separate territories.

You can often keep a male-female pair or a group of females together more peacefully. Females are typically smaller and have a more rounded dorsal fin, while males are larger with a longer, pointed dorsal fin.

Best Tank Mates for Blue Gouramis

Choose tank mates that are peaceful but not too small or timid. Fish with long, flashy fins (like guppies or bettas) are a bad idea, as a gourami might mistake them for a rival and bully them.

Great choices include:

  • Corydoras Catfish
  • Kuhli Loaches
  • Harlequin Rasboras
  • Larger Tetras (like Black Skirt or Serpae)
  • Plecos (like the Bristlenose)
  • Cherry Barbs

Fish to Avoid

Steer clear of fin-nippers and overly aggressive fish. This includes most types of barbs (especially Tiger Barbs), aggressive cichlids, and, as mentioned, male Bettas and fancy Guppies.

Common Problems with Blue Gourami Fish (And How to Solve Them)

Even with the best care, you might encounter an issue. Here are some of the most common problems with blue gourami fish and how to handle them like a pro.

Recognizing Signs of Illness

The first step is observation. A healthy gourami is active, colorful, and has a good appetite. Watch for these warning signs:

  • White spots on the body (a sign of Ich)
  • Frayed or rotting fins (Fin Rot)
  • Lethargy or hiding more than usual
  • Loss of color or appetite
  • Bloating

Most common fish diseases are caused by stress and poor water quality. The best cure is prevention! Perform regular water changes (25% weekly), don’t overstock your tank, and provide a stable environment. If you do spot a disease, quarantine the sick fish in a separate “hospital” tank for treatment.

Managing Male-on-Male Aggression

If you notice one gourami relentlessly chasing another, they need to be separated. This stress can weaken the victim and lead to disease. The best solution is to re-home one of the males or ensure you have a very large, heavily decorated tank (55+ gallons) where they can each claim a territory far away from the other.

The Sustainable Aquarist: Eco-Friendly Blue Gourami Fish Best Practices

Being a responsible aquarist means thinking about our impact on the environment. Embracing a sustainable blue gourami fish approach is easier than you think and ensures the hobby we love can continue for generations.

The best thing you can do is to purchase captive-bred fish. The vast majority of Blue Gouramis in the trade are commercially bred, which is fantastic. This reduces the pressure on wild populations and their natural habitats.

When you’re looking for a eco-friendly blue gourami fish, ask your local fish store about their suppliers. Supporting breeders who prioritize the health and welfare of their fish is a win for everyone. Additionally, dispose of aquarium water responsibly—never pour it into local waterways. Use it to water your houseplants instead; they’ll love the nitrates!

Frequently Asked Questions About Blue Gourami Fish

How big do blue gourami fish get?

Blue Gouramis can reach a full adult size of about 5 to 6 inches (15 cm) in length. It’s important to plan your tank size for their adult size, not the small size you see them at in the store.

Can I keep two blue gouramis together?

It depends. Keeping two males together is highly discouraged unless the tank is very large (55+ gallons) with lots of hiding spots. A male-female pair or a group of all females is a much safer and more peaceful combination for a standard community tank.

Why is my blue gourami changing color?

Color changes can mean several things. They may pale when stressed, sick, or frightened. On the other hand, their colors will become much more vibrant and intense when they are happy, healthy, and ready to spawn. Monitoring their color is a great way to gauge their overall well-being.

Are blue gouramis good for beginners?

Absolutely! They are one of the best “centerpiece” fish for beginners. Their hardiness, adaptability to a range of water parameters, and unfussy diet make them very forgiving. Their engaging personality is a huge bonus that gets new hobbyists hooked!

Your Journey with the Blue Gourami Awaits

The blue gourami fish is truly a gem of the freshwater hobby. They offer the perfect blend of beauty, resilience, and interactive personality that can bring any aquarium to life.
