Highfin Achara Catfish (Leiarius longibarbis)

⚡ Highfin Achara Catfish (Leiarius longibarbis) – Fast-Growing, Bold-Marked, and Monster-Ready

The Highfin Achara Catfish is a powerful and fast-growing South American predator known for its tall dorsal fin, bold contrasting stripes, and aggressive feeding behavior. A relative of the Tiger Shovelnose, the Achara cat is an excellent choice for hobbyists looking to stock large predatory tanks, indoor ponds, or Amazon-themed setups with a hardy, energetic bottom dweller.

These fish are active swimmers with strong personalities. Unlike most bottom-dwelling catfish, Acharas are known to cruise the entire tank level, especially at night—making them a visually dynamic addition to any monster fish display.
