Red Fin Shark

The Red Fin Shark (Epalzeorhynchos frenatum) is a popular freshwater fish native to Southeast Asia, particularly found in the rivers and streams of Thailand, Laos, and Cambodia. This species is easily recognizable by its sleek body, which can reach a maximum length of about 15 cm (6 inches), and its vibrant red or orange fins that contrast beautifully with its dark gray to black body. These striking colors not only make them visually appealing but also serve as a warning to potential predators of their territorial nature and agility in water.

In their natural habitat, Red Fin Sharks inhabit shallow waters with plenty of vegetation, where they can hide from predators. They are highly social fish that thrive in groups, often seen swimming in schools. Their behavior is characterized by playful interactions, darting through the water, and establishing a hierarchy within their groups. This species is also known for its adaptability to various environmental conditions, making it a resilient choice for aquarium enthusiasts.

In terms of care, the Red Fin Shark requires a well-maintained aquarium with plenty of swimming space, as they are active swimmers. They prefer a dimly lit environment with plenty of hiding spots provided by plants and decorations. These fish are known to be semi-aggressive, especially as they mature, so it’s crucial to house them with compatible species that can withstand their spirited nature.

Overall, the Red Fin Shark is not only an eye-catching addition to any aquarium but also an engaging species that brings life and movement to aquatic displays. Their social behavior and striking appearance make them a favorite among both hobbyists and professional aquarists alike.

To successfully care for Red Fin Sharks, importers and retailers should ensure that water parameters are optimal. The recommended temperature range is between 24°C to 28°C, with a pH level of 6.5 to 7.5. These fish thrive in well-filtered water, so maintaining good water quality is essential. A minimum tank size of 150 liters is recommended to provide ample swimming space and a stable environment.

Feeding Red Fin Sharks is straightforward, as they are omnivorous. A varied diet consisting of high-quality flakes, pellets, and occasional live or frozen foods is ideal to promote their health and vibrant coloration. It is important to avoid overfeeding, as this can lead to health issues.

When introducing Red Fin Sharks to a new aquarium, gradual acclimation is crucial. Use a drip acclimation method to help them adjust to the new water conditions. Quarantine new arrivals for at least two weeks to monitor for any signs of disease before introducing them to a community tank. Compatibility should also be considered; they generally do well with other semi-aggressive fish but should be kept away from smaller species that might become targets for bullying.

Red Fin Sharks are suitable for shipping under stable temperature conditions (ideally between 24°C and 28°C). They should be packed securely to minimize stress during transit, with a recommended packing density of no more than 1 fish per 5 liters of water. These fish adapt well during shipping but care must be taken to avoid extreme temperature fluctuations. Currently, there are no CITES restrictions for this species, making it easier for export.
