Licorice Gourami Project – Your Complete Guide To A Thriving

Written ByHoward Parker

Have you ever stared at a nano aquarium and felt something was missing? You’ve seen the neon tetras and the cherry shrimp, but you’re craving a real challenge—a fish that’s as rewarding as it is beautiful, a true aquarist’s jewel.

If that sounds like you, then you’ve stumbled upon the perfect next adventure. The licorice gourami project isn’t just about keeping another fish; it’s about creating a specialized world in miniature. It’s about mastering the subtle art of the blackwater biotope and being rewarded with the sight of some of the most stunning, iridescent fish in the hobby displaying their full glory.

Imagine a dimly lit tank, tea-colored water swirling around tangled driftwood and a carpet of leaf litter. From the shadows, a tiny fish emerges, its fins flashing with electric blue, vibrant red, and deep black. This isn’t just an aquarium; it’s a living piece of art you created. It’s a testament to your skill and dedication.

This comprehensive guide will walk you through every step, transforming you from a curious hobbyist into a confident keeper. Let’s dive in and learn how to build the ultimate home for these incredible creatures.

Why Start a Licorice Gourami Project? The Rewards of Keeping These Tiny Jewels

Before we get into the “how-to,” let’s talk about the “why.” Embarking on a licorice gourami project is a deeply fulfilling experience that elevates your fishkeeping skills. These aren’t your average, throw-in-and-forget community fish. They require a dedicated setup, which is precisely what makes them so special.

One of the biggest benefits of a licorice gourami project is the chance to create a true biotope. You’ll be replicating the soft, acidic, tannin-stained peat swamps of Southeast Asia. This process teaches you an immense amount about water chemistry, botany, and the delicate balance of a natural ecosystem. It’s a masterclass in patient, observant fishkeeping.

And the fish themselves? They are simply breathtaking. In a proper environment, their subtle colors explode. Males will perform mesmerizing courtship dances, flaring their fins and showing off for females. Witnessing this natural behavior, which is impossible in a standard community tank, is the ultimate reward for your hard work.

Don’t worry—while they require specific care, they are surprisingly hardy once their needs are met. This is a perfect project for an aquarist ready to move beyond the basics and create something truly unique.

Choosing Your Stars: A Quick Guide to Parosphromenus Species

The term “licorice gourami” refers to fish in the genus Parosphromenus. There are over 20 recognized species, each with its own unique charm. For your first project, it’s wise to start with one of the more common and adaptable species.

Here are a few popular choices to consider:

  • Parosphromenus deissneri: Often considered the “original” licorice gourami, they are a fantastic starting point. They are slightly more forgiving of minor fluctuations in water parameters.
  • Parosphromenus bintan: Known for the stunning red and blue coloration on the males’ fins. They are active, curious, and a joy to watch.
  • Parosphromenus linkei: A beautiful species with a distinct pattern. They are relatively peaceful and can be a great choice for a dedicated species tank.

When you purchase your fish, try to find a reputable breeder or a local fish store that understands their needs. Healthy licorice gouramis will be active, curious, and show at least a hint of their potential color, even in store tanks. Avoid fish that are hiding, listless, or have clamped fins.

Your Licorice Gourami Project Blueprint: Tank Setup and Aquascaping

This is where the magic begins! Building the perfect environment is the most critical step in this licorice gourami project guide. We’re not just decorating a tank; we’re building an ecosystem. A well-planned setup is the foundation for success.

Tank Size and Placement

Bigger isn’t always better here. Licorice gouramis are small, shy fish that thrive in smaller spaces where they feel secure. A 5 to 10-gallon tank is absolutely perfect for a pair or a small group (1 male, 2-3 females).

Place the tank in a low-traffic area of your home. Constant movement and loud noises can stress them out, causing them to hide and lose their color. A quiet corner in a study or bedroom is ideal.

Substrate and Hardscape

The goal is to create a dark, complex environment. This is one of the most important licorice gourami project tips we can offer.

  • Substrate: Use a dark-colored, inert sand. Avoid crushed coral or any substrate that can raise your water’s pH and hardness.
  • Wood: Spiderwood or small pieces of driftwood are essential. They provide hiding places and release beneficial tannins that help create the blackwater effect.
  • Leaf Litter: This is non-negotiable! A layer of dried Indian almond leaves, oak leaves, or guava leaves on the substrate is crucial. It provides cover, releases tannins, and encourages the growth of microorganisms (infusoria) that serve as a natural food source.

Filtration and Heating

These fish come from slow-moving, almost stagnant waters. They despise strong water flow. A gentle, air-driven sponge filter is the best option. It provides excellent biological filtration without creating a disruptive current.

A reliable, adjustable aquarium heater is also a must. Aim for a stable temperature between 72-79°F (22-26°C). Temperature stability is more important than hitting a specific number, so avoid frequent fluctuations.

Lighting

Dim lighting is key. Bright, intense light will wash out their colors and make them permanently shy. A simple, low-power LED light is sufficient. You can further diffuse the light by adding floating plants like Salvinia or Frogbit. This creates a beautiful, dappled light effect that mimics their natural habitat.

The Secret Sauce: Mastering Blackwater Conditions

If the tank is the body of your project, the water is its lifeblood. This is often the part that intimidates aquarists, but it’s simpler than it sounds. Understanding how to licorice gourami project successfully means understanding their water.

Licorice gouramis require extremely soft, acidic water. Your tap water is likely too hard and alkaline. The best practice is to start with Reverse Osmosis (RO) or distilled water, which is pure and has a neutral pH and zero hardness.

From there, you “rebuild” the water to their liking:

  1. Lower the pH: The tannins from your driftwood and leaf litter will naturally lower the pH. You can also filter the water through peat moss.
  2. Add Botanicals: Indian almond leaves are your best friend. They release tannins, humic acids, and other beneficial compounds that have anti-fungal and anti-bacterial properties.
  3. Aim for these parameters:
    • pH: 4.0 – 6.5 (Aim for stability within this range)
    • GH (General Hardness): 0 – 3 dGH
    • KH (Carbonate Hardness): 0 – 2 dKH
    • TDS (Total Dissolved Solids): Below 80 ppm, ideally below 50 ppm.

Don’t chase perfect numbers. Instead, focus on creating a stable environment. Use a quality liquid test kit to monitor your parameters, especially when you are first setting up the tank. This is a core tenet of any sustainable licorice gourami project.

Feeding Fussy Eaters: A Diet for Vibrant Health and Color

You can do everything else right, but if you don’t nail their diet, your fish will never truly thrive. Licorice gouramis are micropredators. In the wild, they hunt for tiny insects, larvae, and crustaceans.

They will almost always reject dry flakes or pellets. A diet of live and frozen foods is essential for their health and for triggering spawning behavior. Variety is key!

Best Foods for Licorice Gouramis:

  • Live Foods: Baby brine shrimp, daphnia, mosquito larvae, and microworms are all excellent choices. Culturing your own live food is a fantastic, eco-friendly licorice gourami project practice that ensures a constant, nutrient-rich supply.
  • Frozen Foods: Bloodworms, daphnia, and brine shrimp are good frozen options. Thaw them in a small cup of tank water before feeding.

Feed small amounts once or twice a day. Only give them what they can consume in a minute or two to avoid polluting the small volume of water in their tank.

Troubleshooting: Common Problems with a Licorice Gourami Project

Even with the best planning, you might run into a few bumps. Here are some common problems with a licorice gourami project and how to solve them.

  • Problem: Fish are hiding constantly and look pale.

    Solution: Your lighting is likely too bright, or there isn’t enough cover. Add more floating plants, leaf litter, and small caves or coconut huts. Ensure the tank is in a quiet location.

  • Problem: Fish develop a fuzzy, white growth (fungal infection).

    Solution: This is often caused by poor water quality or stress. Perform a small water change with properly prepared water. Add more Indian almond leaves, as their tannins have natural anti-fungal properties. Ensure the temperature is stable.

  • Problem: Fish aren’t eating.

    Solution: They are likely stressed from a recent move or are being picky. Try a different type of live food. Daphnia or mosquito larvae are often irresistible. Ensure the water parameters are in the ideal range.

Frequently Asked Questions About Your Licorice Gourami Project

Can I keep licorice gouramis with other fish?

It’s strongly recommended to keep them in a species-only tank. Their small size and shy nature mean they are easily outcompeted for food and stressed by more active tank mates. If you must add companions, consider tiny, peaceful species that also thrive in blackwater, like Chili Rasboras (Boraras brigittae), but a dedicated tank is always the best practice.

How often should I do water changes?

In a small, well-maintained tank, a 10-20% water change once a week is usually sufficient. It’s crucial that the new water is pre-mixed to match the tank’s temperature and parameters *before* you add it. Shocking them with different water chemistry can be fatal.

My licorice gouramis aren’t breeding. What can I do?

Breeding is a sign that they feel completely safe and comfortable. Ensure your water parameters are perfect, especially the low pH and softness. Condition them with plenty of high-quality live foods. Provide small, dark caves for them to spawn in—tiny PVC pipes or film canisters hidden in the leaves work great.
