Community Fish Spotlight: Phoenix Rasbora (Boraras merah)

When it comes to vibrant and captivating additions to a community aquarium, the Phoenix Rasbora (Boraras merah) stands out as a top contender. Known for their striking coloration and peaceful temperament, these tiny fish can transform any tank into a lively and visually stunning underwater world. In this article, we'll delve into everything you need to know about the Phoenix Rasbora, from its natural habitat to its care requirements, ensuring you can provide the best environment for these dazzling fish.

A Glimpse into the Wild

The Phoenix Rasbora hails from the freshwater streams and peat swamps of Southeast Asia, particularly in Indonesia and Malaysia. These environments are characterized by soft, acidic water rich in tannins, often resulting in a tea-colored appearance. In the wild, Phoenix Rasboras thrive in densely vegetated areas, where they can find plenty of hiding spots and microfauna to feed on.

Appearance and Behavior

One of the main attractions of the Phoenix Rasbora is its vibrant coloration. These diminutive fish, reaching only about 1 inch (2.5 cm) in length, boast a stunning red-orange hue with a shimmering iridescence that can capture the light beautifully. Their bodies are slender and streamlined, with a distinctive black stripe running from the eye to the tail, sometimes accompanied by a few small black spots.

Phoenix Rasboras are schooling fish, meaning they feel most comfortable and display their best colors when kept in groups. A minimum of six individuals is recommended, but larger groups are even better. Their peaceful nature makes them excellent tank mates for other small, non-aggressive fish species, as well as for shrimp and snails.

Setting Up the Perfect Tank

Creating an ideal environment for your Phoenix Rasboras involves mimicking their natural habitat as closely as possible. Here are some key considerations:

Tank Size

Despite their small size, Phoenix Rasboras benefit from having ample space to swim. A tank of at least 10 gallons is recommended for a small school, but larger tanks will provide a more stable environment and allow for a more impressive display.

Water Parameters

Maintaining appropriate water conditions is crucial for the health of Phoenix Rasboras. Aim for the following parameters:

• Temperature: 68-82.4°F (20-28°C)
• pH: 6.0-7.3 (acidic water is preferred)
• Hardness: 1-5 dGH (soft water)

Regular water changes and a good filtration system will help keep the water clean and stable.

Phoenix Rasboras (Boraras merah) are known for their unique courtship displays, where males perform intricate dances to attract females during the breeding season.

Aquascaping

When it comes to decorating the tank, think lush and natural. Dense planting with live plants such as Java moss, Anubias, and floating plants will provide shelter and comfort for your Phoenix Rasboras. Adding driftwood and leaf litter can help recreate the tannin-rich waters of their native habitat, creating a more authentic environment.

Anubias plants attached to driftwood provide Phoenix Rasboras with essential hiding spots and natural filtration, enhancing their well-being and mimicking their natural habitat.

Botanicals

Incorporating botanicals into your tank can greatly enhance the living conditions for Phoenix Rasboras. Botanicals, such as Indian almond leaves, alder cones, and various seed pods, release beneficial tannins and humic substances into the water. These compounds help create a soft, acidic environment similar to their natural habitat and can have antibacterial and antifungal properties, promoting the health of your fish.

Botanicals also provide additional hiding spots and foraging areas, encouraging natural behaviors. When adding botanicals to your tank, start with a small amount and gradually increase, monitoring the water parameters to ensure stability. Over time, as the botanicals break down, they contribute to the biological diversity of the tank, fostering a more balanced ecosystem.

Lighting and Substrate

Soft, subdued lighting will bring out the best colors in your Phoenix Rasboras and reduce stress. A dark substrate, such as black sand, fine gravel or Strata can enhance their vibrant coloration and create a striking contrast.

AquaZen Strata substrate creates an ideal environment for Phoenix Rasboras, promoting vibrant colors and healthy plant growth while maintaining optimal water quality.

 

Feeding and Nutrition

Phoenix Rasboras eagerly feast on nutritious Moina water fleas, showcasing their natural hunting behavior and vibrant colors.

Phoenix Rasboras are micro-predators, feeding on small invertebrates, zooplankton, and insect larvae in the wild. In captivity, they accept a variety of foods, including high-quality micro pellets, crushed flakes, and frozen or live foods like daphnia, brine shrimp, and micro worms. Offering a varied diet will ensure they receive all the necessary nutrients for optimal health and coloration.

Breeding Phoenix Rasboras

Breeding Phoenix Rasboras in the home aquarium can be a rewarding experience. To encourage spawning, set up a separate breeding tank with similar water conditions and plenty of fine-leaved plants or spawning mops. Condition the breeding pair with high-quality live and frozen foods. The female will scatter her eggs among the plants, and once spawning is complete, it's best to remove the adults to prevent them from eating the eggs. The eggs will hatch in about 24-48 hours, and the fry can be fed with infusoria or powdered fry food until they are large enough to accept larger foods.
