Thick Lipped Gourami: Your Ultimate Guide To This Peaceful Gem

Written ByHoward Parker

Are you searching for a freshwater fish that’s bursting with color, full of personality, and won’t stir up trouble in your community tank? It can feel like a challenge to find that perfect centerpiece fish that is both beautiful and peaceful.

I’m here to tell you that your search is over. The wonderful thick lipped gourami (Trichogaster labiosa) is the answer, and this guide will give you everything you need to help this delightful fish not just survive, but truly thrive in your care.

Don’t worry—these fish are perfect for beginners but still loved by experts! In this complete thick lipped gourami care guide, we’ll dive into the ideal tank setup, perfect water parameters, diet, compatible tank mates, and even how to solve common problems before they start. Let’s get started!

What Makes the Thick Lipped Gourami So Special?

Before we get into the nitty-gritty of care, let’s talk about why so many aquarists fall in love with this fish. Understanding their nature is the first step in providing them with a happy home.

Appearance and Varieties

The thick lipped gourami gets its name from its noticeably thicker lips compared to its cousins, like the Dwarf Gourami. Males are the true showstoppers, especially during breeding. They display a stunning deep orange or reddish-brown body with vibrant turquoise blue fins that seem to shimmer under the light.

Females are more subdued, typically showing a silvery-brown or golden hue. This difference makes them easy to sex once they mature. You’ll also find a popular color morph known as the “Sunset” or “Red Robin” gourami, which boasts an even more intense, solid reddish-orange color.

A Peaceful Personality

One of the greatest benefits of thick lipped gourami is their temperament. They are famously peaceful and a bit shy, preferring a calm environment. Unlike some other gourami species that can be territorial bullies, these gentle giants (well, gentle 3-4 inch fish) tend to mind their own business.

You’ll often see them gracefully exploring the mid-to-top levels of the tank, using their long, thread-like ventral fins to “feel” their surroundings. It’s this curious and gentle nature that makes them such a joy to watch.

Sourcing a Sustainable Thick Lipped Gourami

At Aquifarm, we believe in responsible fishkeeping. When you’re ready to add one to your tank, we encourage seeking out a sustainable thick lipped gourami. This means purchasing from reputable local fish stores or breeders who prioritize the health and well-being of their fish over mass production.

An eco-friendly approach ensures you get a healthier, more robust fish and supports ethical practices within the hobby. A well-bred fish is less prone to the diseases that can plague mass-produced specimens.

The Ideal Aquarium Setup: A Thick Lipped Gourami Guide

Creating the right environment is the most crucial part of fishkeeping. Think of yourself as an architect for a tiny aquatic world. Here’s how to build the perfect home for your gourami.

Tank Size and Shape

While not massive fish, they need room to swim and establish a small territory. A minimum of a 20-gallon tank is recommended for a single or a pair. A longer tank is better than a tall one, as it provides more horizontal swimming space.

If you plan on a larger community tank, a 30-gallon or larger will give everyone enough space to coexist peacefully. Overcrowding is a major source of stress for fish, so always err on the side of a larger tank.

Substrate and Decorations

A soft, dark-colored sand or fine gravel substrate is ideal. A darker substrate not only mimics their natural habitat but also helps their vibrant colors pop!

Provide plenty of hiding spots using driftwood, smooth rocks, and caves. These structures give your gourami a sense of security, which is key for this sometimes-shy species. A confident fish is a healthy fish!

The Importance of Live Plants

This is one of the most important thick lipped gourami tips I can offer: plant your tank heavily! These fish come from slow-moving, densely vegetated waters in India and Myanmar. They feel most at home in a lush, planted aquarium.

  • Floating Plants: Species like Frogbit or Red Root Floaters are fantastic. They dim the lighting slightly and provide cover, making your gourami feel safe.
  • Tall Plants: Plants like Java Fern, Anubias, and Amazon Swords provide great hiding spots and visual barriers.
  • Carpeting Plants: While not essential, something like Dwarf Sagittaria can complete the natural look.

Filtration and Gentle Water Flow

Gouramis are labyrinth fish, meaning they have a special organ that allows them to breathe atmospheric air from the surface. They are adapted to slow-moving waters and do not appreciate strong currents.

Choose a filter that provides excellent biological and mechanical filtration but has an adjustable outflow. A hang-on-back filter with a baffle or a gentle sponge filter are both excellent choices. The goal is clean water with minimal disturbance.

Water Parameters and Maintenance: Thick Lipped Gourami Best Practices

Maintaining stable water conditions is the secret to long-term success in the aquarium hobby. These fish are quite hardy, but they still need consistency. This section covers the best practices for their care.

Key Water Parameters

Getting these three right is fundamental. I recommend investing in a good quality liquid test kit (like the API Freshwater Master Test Kit) to monitor your water accurately.

  1. Temperature: Keep the water between 72-82°F (22-28°C). A stable temperature is more important than a specific number, so an aquarium heater is a must.
  2. pH Level: Aim for a pH between 6.0 and 7.5. They are adaptable, but will do best in slightly acidic to neutral water.
  3. Water Hardness: They prefer soft to moderately hard water, generally between 5-15 dGH.

The Nitrogen Cycle: A Non-Negotiable

Before you even think about adding fish, your aquarium must be “cycled.” This is the natural process where beneficial bacteria establish themselves in your filter and substrate, converting toxic ammonia (from fish waste) into less harmful nitrate.

Skipping this step is the number one cause of new fish death. It’s a process that can take several weeks, but your patience will be rewarded with a stable, healthy environment for your fish.

Routine Maintenance Schedule

Consistency is key. A simple weekly routine will keep your tank pristine and your gourami happy.

  • Perform a 25% water change every week.
  • Use a gravel vacuum to clean debris from the substrate.
  • Gently wipe any algae from the glass.
  • Check your filter and rinse the media in the old tank water you removed (never tap water, as chlorine kills beneficial bacteria!).

A Healthy Diet: Feeding Your Thick Lipped Gourami

A varied diet is essential for vibrant colors and a strong immune system. Fortunately, these fish are not picky eaters!

What Do They Eat? An Omnivore’s Menu

In the wild, they eat small insects, crustaceans, and plant matter. We can replicate this with a mix of high-quality prepared and frozen foods.

  • Staple Food: A high-quality tropical flake or small pellet food should be the foundation of their diet.
  • Frozen/Live Foods: Supplement their diet 2-3 times a week with treats like frozen brine shrimp, daphnia, or bloodworms. They will go crazy for these!
  • Vegetable Matter: They will also appreciate blanched vegetables like zucchini or shelled peas, and will often nibble on algae in the tank.

How Much and How Often?

Feed small amounts once or twice a day. A good rule of thumb is to only give them what they can consume completely in about two minutes. Overfeeding is a common mistake that pollutes the water and can lead to health problems.

Peaceful Coexistence: Choosing the Right Tank Mates

Building a harmonious community tank is one of the most rewarding aspects of the hobby. The peaceful nature of the thick lipped gourami makes it an excellent candidate, but you still need to choose its neighbors wisely.

Great Companions

Look for other peaceful, similarly sized fish that enjoy the same water conditions. Good choices include:

  • Corydoras Catfish (they occupy the bottom of the tank)
  • Kuhli Loaches
  • Small Tetras (Neons, Cardinals, Rummy Nose)

    • – Harlequin Rasboras

  • Otocinclus Catfish
  • Peaceful Barbs (like Cherry Barbs)

Species to Avoid

Stay away from fin-nippers and overly aggressive fish. Their long, delicate ventral fins are an easy target. Also, avoid other labyrinth fish like Bettas or other large Gouramis, as the males can become territorial rivals.

  • Tiger Barbs
  • Most Cichlids (except for very peaceful dwarf varieties like Rams)
  • Bettas (Siamese Fighting Fish)
  • Other large Gourami species

Common Problems with Thick Lipped Gourami (And Solutions!)

Even with the best care, issues can sometimes arise. Knowing what to look for is half the battle. This is a critical part of any thick lipped gourami care guide.

Spotting Early Signs of Illness

Observe your fish daily. It’s the best way to catch problems early. Look for:

  • Lethargy or hiding more than usual
  • Clamped fins (fins held tight against the body)
  • Loss of appetite or spitting out food
  • Erratic swimming or rubbing against objects (“flashing”)
  • Visible spots, sores, or fuzzy patches

Common Ailments: Ick and Fin Rot

Two of the most common issues are Ich (white spot disease) and fin rot. Both are often triggered by stress from poor water quality.

For Ich, you’ll see tiny white salt-like specks on the fish’s body and fins. It’s best treated by slowly raising the tank temperature to 82-84°F and using a commercial Ich medication.

Fin Rot appears as frayed, ragged, or decaying fins. This is a bacterial infection, almost always caused by poor water conditions. The first line of defense is a large water change and ensuring your parameters are perfect. If it persists, antibacterial medication may be needed.
