In the fascinating world of aquatic life, the Licorice Gourami (Parosphromenus deissneri) emerges as a captivating species that has captured the hearts of aquarists worldwide. This diminutive fish, hailing from the Osphronemidae family, is a close relative of the well-known Bettas and Gouramis. Its scientific name pays homage to the German ichthyologist, Alfred Deissner, who first described the species in the late 19th century.

    The Licorice Gourami’s allure lies not only in its striking appearance but also in its intriguing behavior and unique habitat preferences. As a mid-dweller, this fish can often be found navigating the middle layers of the aquarium, adding a dynamic presence to any well-crafted underwater landscape. With a diet that primarily consists of small invertebrates and algae, the Licorice Gourami is a relatively easy species to cater to in captivity.

    Interestingly, the Licorice Gourami has been graced with various monikers in the aquarium trade. Some may recognize it as the “Liquorice Gourami” or the “Deissner’s Licorice Gourami,” all paying homage to its distinctive coloration reminiscent of the beloved confectionery. These alternative names have only added to the fish’s popularity among enthusiasts seeking a touch of sweetness in their aquatic setups.

    Hailing from the peat swamps and slow-moving streams of Southeast Asia, particularly in Indonesia and Malaysia, the Licorice Gourami has adapted to thrive in specific water conditions. With a preference for slightly acidic and soft water, replicating its natural habitat is key to ensuring the fish’s well-being in captivity. Aquarists who go the extra mile to create a biotope-style aquarium, complete with a sandy substrate, driftwood, and dense vegetation, are often rewarded with a thriving community of these enchanting creatures.

    One fun fact about the Licorice Gourami is its remarkable ability to breathe atmospheric air. Like many of its Labyrinth fish cousins, this species possesses a unique organ that allows it to extract oxygen directly from the air above the water’s surface. This adaptation has enabled the Licorice Gourami to survive in environments where dissolved oxygen levels may be low, showcasing the incredible resilience of nature.

    When considering tank mates for the Licorice Gourami, it is essential to keep in mind its peaceful temperament and relatively small size. Ideal companions include other small, non-aggressive species such as Rasboras, Tetras, and shrimp. By carefully selecting compatible tank mates and providing ample hiding spots and territories, aquarists can create a harmonious and visually stunning underwater community.

    Ideal Tank Mates

    When selecting tank mates for the Licorice Gourami (Parosphromenus deissneri), it is essential to consider the fish’s peaceful temperament, small size, and specific habitat requirements. Ideal tank mates should share similar water parameters, exhibit non-aggressive behavior, and not outcompete the Licorice Gourami for food or space.

    Compatibility is key to creating a harmonious and thriving aquatic environment. The Licorice Gourami’s shy and reclusive nature means that it should be housed with species that will not intimidate or harass it.

    FAQs

    How often should I feed my Licorice Gourami?

    It’s best to feed your Licorice Gourami small amounts of food 2-3 times a day. This feeding schedule mimics their natural eating habits and helps maintain good water quality by reducing the amount of uneaten food that can decay in the aquarium.

    Are Licorice Gouramis sensitive to changes in water parameters?

    Yes, Licorice Gouramis are quite sensitive to fluctuations in water parameters. They require stable conditions, particularly in terms of pH and temperature. It’s essential to perform regular water tests and make any necessary adjustments gradually to avoid stressing your fish.

    Can I keep multiple Licorice Gouramis in the same aquarium?

    While it is possible to keep multiple Licorice Gouramis together, it’s important to ensure that the aquarium is spacious enough to provide each fish with its own territory. A good rule of thumb is to allow at least 5 gallons (19 liters) of water per Gourami. It’s also crucial to maintain a balanced male-to-female ratio to minimize aggression.

    How can I encourage my Licorice Gouramis to breed?

    To encourage breeding, provide your Licorice Gouramis with a well-maintained, heavily planted aquarium with soft, acidic water. Gradually increase the temperature to around 80°F (27°C) and feed them a diet rich in live or frozen foods. Provide a shallow spawning dish or a flat surface with broad leaves for the female to lay her eggs on.

    Are Licorice Gouramis prone to any specific diseases?

    Like most fish, Licorice Gouramis can be susceptible to common aquarium diseases such as ich, velvet, and bacterial infections if water quality is poor or if they are stressed. Maintaining stable water parameters, performing regular water changes, and quarantining new fish can help prevent the spread of disease.

    How can I tell if my Licorice Gourami is stressed?

    Signs of stress in Licorice Gouramis include loss of appetite, lethargy, hiding for extended periods, rapid breathing, and a loss of color intensity. If you notice any of these symptoms, check your water parameters and consider potential sources of stress, such as incompatible tank mates or inadequate hiding spots.

    Can I keep Licorice Gouramis in a community aquarium with larger fish?

    It’s not recommended to keep Licorice Gouramis with much larger fish, as they may become intimidated or even preyed upon. Stick to small, peaceful tank mates that share similar water requirements and temperaments to ensure the well-being of your Licorice Gouramis.

    How often should I perform water changes in my Licorice Gourami aquarium?

    Regular water changes are essential to maintain good water quality and keep your Licorice Gouramis healthy. Aim to perform a 10-20% water change once a week, using a gravel vacuum to remove debris and waste from the substrate. Be sure to replace the removed water with dechlorinated water that matches the aquarium’s temperature and parameters.
