    Care Details

    Aquascape: The Phoenix Rasbora thrives in a densely planted aquarium, which resembles its natural habitat. Use fine-leaved plants and floating vegetation to provide hiding spots and diffuse lighting.

    Substrate: A dark-colored substrate complements the vibrant colors of the Phoenix Rasbora and mimics its natural environment. Opt for sand or small-grain gravel.

    Disease Prevention: Maintain good water quality and quarantine new additions to prevent diseases. Regular water changes and proper filtration are key to their health.

    Filtration: Moderate to high filtration is essential, but be mindful of strong currents as the Phoenix Rasbora prefers calmer waters.

    Lighting: Moderate lighting is adequate for their tank. Ensure a natural day-night cycle to support their well-being.

    Water Flow: A gentle water flow mimics their natural habitat, so choose filters and settings that provide moderate circulation.

    Hardiness: Phoenix Rasboras are hardy fish, but they're sensitive to sudden water parameter changes. Keep water conditions stable to ensure their well-being.

    Acclimation: Proper acclimation is crucial. Gradually adjust water temperature and parameters to reduce stress when introducing them to your tank.

    Expected Lifespan: Under suitable conditions, Phoenix Rasboras can live for up to 4-6 years in captivity.

    Special Requirements: They appreciate a well-planted tank with shaded areas and open swimming spaces. Keep them in small groups for comfort and display their vibrant colors best when provided with a dark substrate.

    Temperament and Behavior

    Behavior: Phoenix Rasboras are peaceful and social fish. They tend to stay in the middle and upper levels of the tank, and they're active swimmers, especially in the presence of conspecifics. They have a calm temperament and make an excellent addition to a community aquarium.

    Breeding: Breeding Phoenix Rasboras can be challenging due to their specific requirements. They are egg layers, and breeding involves providing a separate breeding tank with soft, acidic water, fine-leaved plants, and low lighting. Once successful, the parents should be removed as they might consume their own eggs.

    Aggression: Phoenix Rasboras are not aggressive and are well-suited for community tanks. They're more focused on displaying their vibrant colors and exploring their environment rather than engaging in aggressive behavior.

    Tankmates Compatibility: These rasboras are peaceful and get along well with other non-aggressive species of similar size. Suitable tankmates include other rasboras, small tetras, peaceful gouramis, and small bottom-dwelling fish like Corydoras.

    Activity Level: Phoenix Rasboras are active swimmers, and their vibrant colors become more pronounced when they swim in schools. They enjoy exploring the tank and are often seen darting in and out of plants.

    Schooling or Shoaling Behavior: Phoenix Rasboras have a strong schooling instinct, and it's recommended to keep them in groups of at least six individuals. In larger schools, they exhibit more vibrant colors and feel more secure.

    Plant Compatibility: Phoenix Rasboras are generally compatible with live plants. In fact, a well-planted tank replicates their natural habitat and provides them with hiding spots and security.

    Diet and Nutrition

    Dry Foods: Phoenix Rasboras readily accept high-quality dry foods like micro-pellets and flakes. These can make up a significant portion of their diet and are convenient for feeding.

    Frozen Foods: Offering frozen foods like daphnia, brine shrimp, and bloodworms is an excellent way to add variety and ensure your Phoenix Rasboras receive essential nutrients. They relish the novelty and nutritional value of frozen treats.

    Live Foods: Live foods such as small insects, daphnia, and baby brine shrimp are highly appreciated by Phoenix Rasboras. They mimic their natural diet and can be used to entice finicky eaters or condition them for breeding.

    Vegetables: While Phoenix Rasboras are primarily carnivorous, you can occasionally offer blanched and finely chopped vegetables like spinach or zucchini. This provides some fiber and can be a welcome change.

    Algae: Phoenix Rasboras are not known to graze on algae as some other species do. Therefore, their diet should primarily consist of animal-based foods.

    Feeding Schedule: Feed your Phoenix Rasboras small portions 2-3 times a day. This mimics their natural feeding patterns and helps prevent overfeeding, which can lead to water quality issues.

    Supplemental Foods: To ensure their health and vibrant colors, consider occasional supplements with high-quality, vitamin-rich foods. Supplements can help enhance their overall well-being.

    Tank Size: Phoenix Rasboras are small fish, so they can thrive in aquariums with a capacity of 10 gallons (38 liters) or more. A larger tank allows for better swimming space and a more stable environment.

    Tank Length and Measurements: For their comfort, choose a tank with dimensions that suit their natural behavior. A 20-gallon long tank (76 liters) measuring approximately 30 inches (76 cm) in length provides ample swimming space and accommodates their social nature.

    Water Temperature: Maintain the water temperature between 72-82°F (22-28°C). This range mimics their native habitat and ensures their well-being.

    pH (Acidity/Alkalinity): Phoenix Rasboras prefer slightly acidic to neutral water conditions. Aim for a pH level of 6.5 to 7.0 to create an environment that resembles their native streams in Southeast Asia.

    KH (Carbonate Hardness) and GH (General Hardness): Keep the KH and GH values in the soft to moderately hard range. Aim for KH levels of 2-6 dKH and GH levels of 4-8 dGH. These conditions mirror the Rasboras' natural habitat.

    Hardiness: Phoenix Rasboras are generally hardy, but they do best in stable water conditions. Sudden fluctuations in water parameters can stress them, so maintain consistent water quality.

    Nitrate (NO3) Levels: Keep nitrate levels below 20 ppm. Regular water changes, efficient filtration, and careful maintenance will help maintain low nitrate levels, ensuring the health of your Phoenix Rasboras.

    The History, Popularity and Natural Habitat

    History: The Phoenix Rasbora, scientifically known as Boraras merah, is native to the freshwater ecosystems of Southeast Asia, specifically Indonesia and Malaysia. These regions are characterized by slow-moving streams, peat swamp forests, and swampy areas. In their native habitats, Phoenix Rasboras thrive in tannin-stained waters with soft and acidic conditions. Their vibrant red and gold coloration has made them a prized species in the aquarium hobby.

    Popularity: Over the years, the Phoenix Rasbora has gained significant popularity among aquarium enthusiasts. Their striking coloration and peaceful nature make them a sought-after choice for both beginners and experienced hobbyists. Due to their manageable size, they are often included in community tanks and nano aquariums. The availability of Phoenix Rasboras has increased as they are now bred in captivity, making them more accessible to aquarists around the world.

    Natural Habitat: Phoenix Rasboras are well-suited to the blackwater environments of their native regions. In these areas, the water is tinted brown due to the presence of tannins from decaying plant matter. The water is typically soft, with low mineral content, and slightly acidic. Aquatic plants, including floating varieties, are abundant, providing shelter and shade for the fish. Fallen leaves in the water contribute to the unique water chemistry and aesthetics of their habitat. In the wild, Phoenix Rasboras are known for their peaceful and schooling behavior, often seeking refuge among submerged structures and dense aquatic vegetation.

    Understanding their natural habitat is essential for recreating suitable tank conditions, including maintaining water quality, water chemistry, and providing ample plant cover, to ensure the well-being and vibrancy of these captivating fish in an aquarium setting.
