Crossband Chocolate Gourami

Sphaerichthys selatanensis, commonly referred to as the Crossband Chocolate Gourami, is a fascinating species native to the Kalimantan region of Borneo, Indonesia. This small freshwater fish reaches a maximum length of 4 cm and is distinguished by its dark brown body adorned with lighter horizontal bands. Its unique coloration and patterns make it an attractive choice for aquarists looking to add diversity to their freshwater tanks. The Crossband Chocolate Gourami is a facultative air-breather, which allows it to thrive in low-oxygen environments, a characteristic that sets it apart from many other gourami species.

In terms of behavior, males exhibit mouthbrooding, where they carry fertilized eggs in their mouths until they hatch. This protective parental behavior not only contributes to the survival of the young but also adds an engaging dynamic to their care in captivity. Typically found in slow-moving waters such as swamps, marshes, and riverbanks, this species prefers heavily vegetated areas that offer ample hiding spots and breeding grounds.

The Crossband Chocolate Gourami's habitat is characterized by soft, acidic waters rich in organic matter, which influence its coloration and health. Its natural environment is often shaded by dense vegetation, providing a serene atmosphere that mimics the tranquility many aquarists aim to replicate in their aquariums. The species is known for its peaceful demeanor, making it suitable for community tanks, especially when paired with similarly sized or smaller fish.

Due to its size and unique features, the Crossband Chocolate Gourami is an ideal candidate for nano aquariums or specialized gourami setups. These fish thrive in well-maintained tanks that mimic their natural habitat, ensuring a healthy and vibrant display that captivates both enthusiasts and casual aquarists alike.

When caring for the Crossband Chocolate Gourami, it is essential to provide optimal water parameters to ensure its health and well-being. The ideal temperature range is between 24 to 28 degrees Celsius, with a pH level of 6.0 to 7.5. This species prefers soft, slightly acidic water, and regular water changes are crucial to maintain water quality. The tank should be well-planted with floating plants and dense vegetation to simulate their natural habitat, offering the fish both shelter and a breeding ground.

Feeding should consist of a varied diet that includes high-quality flake foods, frozen or live foods such as brine shrimp and daphnia, ensuring they receive adequate nutrition. Compatibility-wise, the Crossband Chocolate Gourami is generally peaceful and can be housed with other small, non-aggressive species. However, care should be taken when introducing new tank mates, as stress can impact their health.

Acclimation is critical when introducing these fish to a new environment; a slow drip acclimation method is recommended to minimize stress. A quarantine period of at least two weeks is advisable for new arrivals to prevent the spread of any potential diseases. By following these care guidelines, importers and retailers can ensure the health and vitality of the Crossband Chocolate Gourami, making them a delightful addition to any freshwater display.

The Crossband Chocolate Gourami is suitable for shipping and can be packed in bags with sufficient oxygen to maintain well-being during transit. A packing density of up to 10 fish per liter is recommended to ensure they have enough space. Due to their sensitivity to temperature fluctuations, it is crucial to maintain a stable shipping environment, ideally within the 24 to 28 degrees Celsius range. This species is not listed under CITES, making it easier for exporters to manage compliance with international regulations.
