Discover the Highfin Achara Catfish (Leiarius longibarbis)

The Highfin Achara Catfish is a striking freshwater species, prized by aquarium enthusiasts for its unique appearance and fascinating behavior. Known scientifically as Leiarius longibarbis, this catfish stands out with its elongated barbels and distinctive high dorsal fin, making it a captivating addition to any large freshwater tank.

Size and Growth

Adult Highfin Achara Catfish can reach an impressive size, typically growing up to 16 inches (40 cm) in length. Because of their substantial size, these catfish require ample swimming space and a well-maintained environment to thrive.

Temperament and Behavior

Generally peaceful, the Highfin Achara Catfish exhibits a calm and shy demeanor. They are nocturnal bottom-dwellers, often hiding during daylight hours and becoming more active at night. Despite their large size, they typically coexist peacefully with other non-aggressive species, though they may consume very small tankmates.

Recommended Tank Size and Setup

Given their size and active nature, a minimum tank size of 75 gallons is recommended for a single specimen to provide adequate space. A well-structured aquarium with plenty of hiding spots, such as driftwood, caves, and dense vegetation, mimics their natural habitat and helps reduce stress.

Ideal Water Parameters

• Temperature: 72-79°F (22-26°C)
• pH: 6.0-7.5
• Hardness: Soft to moderately hard water (2-15 dGH)

Maintaining stable water conditions with regular filtration and partial water changes is crucial to keep the Highfin Achara Catfish healthy and active.

Diet and Feeding

This species is an opportunistic omnivore with a diet that includes both protein-rich and plant-based foods. In captivity, they thrive on a varied diet consisting of high-quality sinking pellets, live or frozen bloodworms, brine shrimp, and occasional vegetable matter such as blanched zucchini or spinach. Feeding should be done in the evening to align with their nocturnal feeding habits.

Compatibility with Other Fish

Highfin Achara Catfish generally get along well with other peaceful, similarly sized fish species. Avoid housing them with aggressive or much smaller fish that may become prey. Suitable tank mates include larger tetras, cichlids with calm temperaments, and other bottom-dwellers like Plecos. Their shy nature means they appreciate a peaceful community without excessive competition for food.

• Unique high dorsal fin and elegant barbels add visual interest.
• Peaceful temperament suitable for community tanks with appropriate species.
• Relatively hardy and adaptable when kept in proper conditions.
