Written ByHoward Parker

Are you dreaming of a peaceful, vibrant aquarium that doesn’t take over your entire living room? A tank filled with gentle, curious fish that shimmer with a warm, golden glow? If you’ve been searching for the perfect centerpiece fish for a smaller setup, you’ve likely come across the delightful Honey Gourami. But it’s easy to feel a little lost wondering if a 20-gallon tank is truly the right size for them to thrive.

I promise you, it absolutely is. In fact, a honey gourami 20 gallon tank is one of the most rewarding and beautiful setups you can create, especially if you’re just starting your journey or want a stunning nano aquarium. It’s the perfect balance of space for the fish and manageability for you.

In this complete guide, we’ll walk you through everything you need to know. We’ll cover why a 20-gallon is the ideal choice, exactly how to set it up from scratch, the best tank mates to choose, and how to solve common problems before they start. Let’s build your underwater paradise together!

Why a 20-Gallon Tank is the Sweet Spot for Honey Gouramis

You might see tiny Honey Gouramis in a pet store and think a 10-gallon tank is enough. While they can survive in smaller tanks, a 20-gallon aquarium allows them to truly thrive. Think of it as the difference between living in a small studio apartment versus a comfortable one-bedroom home—both work, but one offers a much higher quality of life.

Here are the key benefits of a honey gourami 20 gallon tank:

  • Stable Water Parameters: This is the single biggest advantage. More water volume means that toxins like ammonia and nitrite dilute more easily. Temperature and pH also remain more stable, creating a less stressful and healthier environment for your fish.
  • Ample Swimming Space: Honey Gouramis (Trichogaster chuna) are curious explorers. They love to investigate every nook and cranny, from the substrate to the surface. A 20-gallon “long” tank, in particular, gives them the horizontal space they crave.
  • Room for Friends: A 20-gallon setup provides enough territory to house a pair or trio of Honey Gouramis and a small school of peaceful tank mates. This creates a more dynamic and interesting community aquarium.
  • Lush Aquascaping Potential: You have enough room to create a beautifully planted aquascape with driftwood and rocks. This isn’t just for looks; it provides essential hiding spots and security for your gouramis, which helps them feel safe and display their best colors.

Setting Up Your Honey Gourami 20 Gallon Tank: The Blueprint

Alright, let’s get our hands wet! Setting up the tank correctly from the start is the most important step. This is your complete honey gourami 20 gallon tank guide to building a perfect home for these little gems.

Essential Equipment Checklist

Don’t worry—you don’t need a ton of complicated gear. Here’s a simple list of the must-haves:

  1. A 20-Gallon Aquarium: A “20 long” (30″ x 12″ x 12″) is ideal as it provides more surface area and horizontal swimming room than a “20 high.”
  2. Gentle Filtration: Honey Gouramis come from slow-moving waters. A powerful filter will buffet them around. Opt for a quality hang-on-back filter with an adjustable flow or a small sponge filter. Pro-tip: A sponge filter is fantastic as it also provides a surface for beneficial bacteria and microorganisms for your gouramis to graze on.
  3. Adjustable Heater: These are tropical fish! You’ll need a reliable 50-75 watt heater to keep the water a consistent 74-82°F (23-28°C). Aim for a sweet spot around 78°F.
  4. Aquarium Lid: This is non-negotiable. Gouramis are anabantoids, meaning they have a “labyrinth organ” that allows them to breathe air from the surface. A lid keeps the air above the water warm and humid, protecting this delicate organ. It also prevents any surprise jumps!
  5. Low-to-Moderate Lighting: Bright, intense light can stress them out. A standard LED light suitable for growing low-light plants like Anubias and Java Fern is perfect.

Substrate and Hardscape: Building the Foundation

The “hardscape” is the bones of your aquarium—the rocks and wood that create the layout. For a natural look that your gouramis will love, use a dark-colored sand or fine gravel substrate. This will make their golden-orange colors pop!

Incorporate pieces of driftwood or spiderwood to create interesting shapes and hiding places. Smooth river stones can also be used to build small caves. This structure is crucial for making your shy gouramis feel secure.

The Magic of Live Plants

A planted tank is the absolute best environment for Honey Gouramis. Plants provide cover, improve water quality, and create a natural, calming habitat. Don’t be intimidated—you don’t need to be an expert aquascaper!

Here are some easy, beginner-friendly plants that are perfect for your setup:

  • Floating Plants: Frogbit or Red Root Floaters are fantastic. They dim the light and provide cover at the surface, which is exactly where gouramis love to hang out and build their bubble nests.
  • Java Fern & Anubias: These hardy plants don’t even need to be planted in the substrate. Simply attach them to your driftwood or rocks with super glue gel or cotton thread.
  • Cryptocoryne wendtii: A beautiful, low-maintenance plant that comes in green or bronze varieties and fills out the mid-ground nicely.
  • Vallisneria or Hornwort: These tall background plants create a lush, jungle-like feel and offer great hiding spots.

Bringing Your Tank to Life: Stocking & Tank Mates

This is the fun part! But patience is key. Before adding any fish, you must cycle your tank. This process establishes the beneficial bacteria needed to break down fish waste. It usually takes 4-6 weeks, so plan ahead.

How Many Honey Gouramis?

For a honey gourami 20 gallon tank, you have a few great options:

  • A Single Male: A lone male can be a stunning centerpiece and will be very interactive with you.
  • A Pair (Male/Female): This is a classic choice. You may even get to witness fascinating breeding behavior, like the male building a bubble nest.
  • A Trio (One Male, Two Females): This is often the best option. It allows the male to display his natural behaviors without harassing a single female too much.

Avoid keeping two males together in a 20-gallon tank. While generally peaceful, they can become territorial with each other, leading to stress and fighting.

Peaceful Tank Mates

Honey Gouramis are gentle souls, so they need equally peaceful neighbors. Avoid anything nippy, boisterous, or aggressive. Excellent choices include:

  • Small Rasboras: Chili Rasboras, Phoenix Rasboras, or Harlequin Rasboras are perfect. A school of 8-10 looks amazing.
  • Small Tetras: Neon Tetras, Ember Tetras, or Green Neon Tetras work well. Again, a school of 8-10 is best.
  • Pygmy Corydoras: These adorable bottom-dwellers are tiny, peaceful, and stay out of the gouramis’ way. A group of 6-8 is ideal.
  • Kuhli Loaches: These quirky, noodle-like fish are fascinating to watch and are excellent, peaceful tank mates.
  • Snails & Shrimp: Nerite snails are fantastic algae eaters, and Amano or Cherry Shrimp can coexist peacefully if there are plenty of plants for them to hide in.

Daily Care & Feeding: Honey Gourami 20 Gallon Tank Best Practices

Once your tank is up and running, daily care is simple and rewarding. This honey gourami 20 gallon tank care guide will keep your fish happy and healthy for years to come.

A Healthy Diet

Variety is the spice of life! In the wild, Honey Gouramis are omnivores that eat small insects and crustaceans. To replicate this, feed a high-quality micro-pellet or flake food as a staple.

Supplement their diet 2-3 times a week with frozen or live foods like:

  • Daphnia
  • Brine Shrimp
  • Bloodworms (as an occasional treat)

Only feed what they can consume in about a minute, once a day. Overfeeding is one of the most common mistakes in the hobby and leads to poor water quality.

Water Changes & Maintenance

A consistent maintenance schedule is the secret to a stable, healthy aquarium. For a 20-gallon tank, a 25-30% water change once a week is a perfect routine.

During the water change, use a gravel vacuum to gently clean a portion of the substrate. Don’t forget to wipe down the inside of the glass to remove any algae. Always treat new water with a water conditioner to remove chlorine and chloramine before adding it to the tank.

Common Problems with a Honey Gourami 20 Gallon Tank (and How to Solve Them)

Even with the best care, you might run into an issue or two. Don’t panic! Here are some common problems with honey gourami 20 gallon tank setups and their simple solutions.

  • Problem: My Gourami is Hiding All the Time.

    Solution: This is usually a sign of stress or insecurity. Add more cover! More plants, especially floating ones, will make them feel much safer. Check for aggressive tank mates and ensure the water parameters are stable.
  • Problem: My Male Gourami is Chasing the Female Constantly.

    Solution: This is common breeding behavior. Ensure there are plenty of plants and hardscape to break lines of sight. Adding a second female can also help disperse the male’s attention.
  • Problem: My Gourami Isn’t Eating.

    Solution: First, check your water parameters. Poor water quality is a common cause of appetite loss. Try tempting them with high-value live or frozen food like daphnia. If they are new to the tank, they may just need a few days to settle in.

Creating a Sustainable & Eco-Friendly Honey Gourami Habitat

Part of being a responsible aquarist is thinking about our environmental impact. Creating a sustainable honey gourami 20 gallon tank is easier than you think and benefits both your fish and the planet.

Focus on using live plants, which act as natural filters, reducing the need for excessive filter media changes. Opt for energy-efficient LED lighting and set it on a timer for 8-10 hours a day to conserve electricity and control algae growth.

An eco-friendly honey gourami 20 gallon tank also means sourcing your fish responsibly. Look for captive-bred Honey Gouramis from local fish stores or reputable breeders. This reduces the pressure on wild populations and ensures you get a healthier, more acclimated fish.

Frequently Asked Questions About the Honey Gourami 20 Gallon Tank

How many honey gouramis can I keep in a 20 gallon tank?

The best stocking is either a single male, a male/female pair, or a group of one male and two females. Avoid keeping multiple males together, as they can become territorial in this size tank.

Are Honey Gouramis good for beginners?

Absolutely! They are one of the best “first” centerpiece fish. They are hardy, peaceful, and their care requirements are very straightforward, making them perfect for someone new to the hobby. Don’t worry—these fish are perfect for beginners!

Why is my Honey Gourami making bubbles at the surface?

Congratulations! If you have a male, he is likely building a “bubble nest.” This is a completely natural breeding behavior where the male creates a floating nest of bubbles coated in his saliva, hoping to attract a female to lay eggs. It’s a sign he is happy and healthy!

Do Honey Gouramis need a strong filter?

No, they prefer slow-moving water. A strong filter current will stress them out. It’s best to use a gentle hang-on-back filter with an adjustable flow, a sponge filter, or baffle the output of your current filter with a sponge.
