Betta macrostoma
Betta macrostoma, commonly known as the Brunei beauty, is a freshwater fish species belonging to the family Osphronemidae. Native to the waters of Brunei and parts of Borneo, this fish is known for its striking appearance. It exhibits a vibrant coloration, typically featuring hues of blue, green, and yellow, with long, flowing fins that enhance its aesthetic appeal.
Typically found in slow-moving or still waters, Betta macrostoma prefers habitats with dense vegetation where it can take shelter. Unlike its more common relative, the Siamese fighting fish, Betta macrostoma is not as aggressive and tends to exhibit more peaceful behavior when kept in appropriate conditions.
In captivity, they require specific water parameters to thrive, including slightly acidic to neutral pH and a stable temperature range. It is advisable to provide ample hiding spots and plants in the aquarium to replicate their natural environment.
Breeding Betta macrostoma can be challenging due to their specific requirements and the need for a suitable breeding setup. They are bubble-nesters, and the male will create a nest at the surface of the water to attract a female.
Due to habitat loss and over-collection for the aquarium trade, Betta macrostoma is considered vulnerable in the wild. Conservation efforts are essential to ensure that this beautiful species continues to thrive both in nature and in aquarist collections.
Keeping Betta macrostoma in a Water Tank
Betta macrostoma, commonly known as the Brunei beauty, is a striking freshwater fish that requires specific care when kept in a water tank. Here are key factors to consider for a successful setup:
Tank Size
A minimum tank size of 20 gallons is recommended for Betta macrostoma. Larger tanks provide more space for swimming and help maintain stable water parameters.
Water Parameters
Temperature: Maintain a water temperature between 76°F to 82°F (24°C to 28°C).
pH Level: Ideal pH should be in the range of 6.0 to 7.5, with 6.5 being optimal.
Hardness: Soft water with a hardness of 2 to 8 dGH is preferred.
Filtration and Aeration
A gentle filtration system is crucial to keep the water clean without creating strong currents, which can stress the fish. Consider using a sponge filter or a filter with adjustable flow. Additionally, provide some aeration to maintain oxygen levels.
Tank Setup
Substrate: Use a fine substrate such as sand or small gravel, which mimics the natural habitat.
Hiding Places: Incorporate plants, driftwood, and rocks to create hiding spots, as Betta macrostoma appreciates areas where it can retreat.
Plants: Live aquarium plants enhance water quality and provide natural cover. Suitable plants include Java moss, Anubias, and floating plants.
Feeding
Betta macrostoma are carnivorous and thrive on a varied diet. Provide high-quality pellets, frozen or live foods such as mosquito larvae, brine shrimp, and daphnia. Feed them small portions 2-3 times a day to ensure they receive adequate nutrition without overfeeding.
Social Behavior
Betta macrostoma can be territorial and aggressive towards their own kind, especially males. It's advisable to keep only one male per tank. If keeping multiple Betta macrostoma, consider adding them to a larger tank with enough hiding spots to minimize aggression.
Maintenance
Regular water changes of 10-20% weekly are necessary to keep the water clean and stable. Regularly monitor water parameters and keep an eye on the fish for any signs of stress or illness.
By providing the right environment and care, you can successfully keep Betta macrostoma in your aquarium, appreciating their beauty and unique behavior.
