Rainbow Shark

Rainbow Shark (Epalzeorhynchos frenatum)
A sleek, semi-aggressive bottom-dweller with a bold black body and vibrant red fins

The Rainbow Shark is a striking freshwater fish known for its jet-black body, vivid red fins, and streamlined, shark-like profile. Active and territorial, it thrives in larger aquariums with plenty of hiding spots and open swimming space. Rainbow Sharks are best kept singly unless the tank is very large and well-structured, as they can become aggressive toward similar species. Hardy and long-lived, they add movement and personality to the lower levels of the aquarium.
