Rasbora Hengeli (Glowlight Rasbora / Hemgel's Rasbora)

Rasbora Hengeli, commonly known as the Glowlight Rasbora or Hemgel's Rasbora, hails from the clear waters of Southeast Asia, particularly in regions of Indonesia and Malaysia. This small, peaceful fish is characterized by its vibrant orange to reddish hues, accentuated by a distinct luminous stripe that runs along its body, giving it a unique glow, especially under dim lighting. These visual features make them a popular choice among aquarists looking to add color and liveliness to their aquatic displays.

In terms of behavior, the Glowlight Rasbora is known for its schooling nature, thriving in groups of six or more. They are generally calm and non-aggressive, making them suitable companions in community tanks with various other small fish species. Their active swimming habits and social interactions add dynamic movement to the aquarium, creating a lively environment.

Typically found in slow-moving rivers and streams, Rasbora Hengeli prefers densely planted areas where they can hide and feel secure. Their natural habitat is characterized by soft, acidic waters, rich in organic matter, which provides them with a sense of safety and encourages natural behaviors. When replicating their environment in captivity, it is essential to include plants and decorations that mimic their native habitat to keep them healthy and stress-free.

The Glowlight Rasbora can live for several years and is relatively hardy, making them an excellent choice for both novice and experienced aquarists. With proper care and attention, they can thrive and display their beautiful coloration, contributing to the overall aesthetic of any freshwater aquarium setup.

To ensure the health and well-being of Rasbora Hengeli, maintain water parameters that mimic their natural environment. The ideal temperature range is between 22°C to 26°C, with a pH level of 6.0 to 7.5. They thrive in soft to moderately hard water, making it essential to monitor these levels regularly. A minimum tank size of 40 liters is recommended to accommodate a small school, which helps reduce stress and encourages natural behavior.

Feeding Glowlight Rasboras is straightforward, as they are omnivores. A varied diet that includes high-quality flake foods, micro-pellets, and occasional live or frozen foods like daphnia or brine shrimp will promote optimal growth and coloration. Ensure that they are fed small portions multiple times a day to keep them active and healthy.

Compatibility-wise, Rasbora Hengeli pairs well with other peaceful fish species, including tetras, danios, and small loaches. It is advisable to avoid housing them with larger or aggressive fish that may intimidate or prey on them. When introducing new fish, proper acclimation is crucial to reduce stress and prevent shock; this can be achieved through a gradual acclimation process over a few hours.

Quarantine new arrivals for at least two weeks in a separate tank to monitor for any signs of illness, ensuring the health of your existing aquatic community before introduction.

Rasbora Hengeli is suitable for shipping due to its relatively hardy nature. When packing, it is essential to maintain a density that allows for adequate oxygen levels, typically one fish per liter of water. Temperature should be kept stable between 22°C to 26°C during transit to minimize stress. This species is not listed under CITES, making shipping regulations straightforward.
