Centropomus ensiferus

A rare, smaller growing species of true snook found in the coastal waters of Northeastern South America, the Swordspine Snook is a unique species for a larger predator aquarium. Unlike most of their relatives, these fish are generally found in pure freshwater to slightly brackish environments, and while they occasionally migrate into strong brackish or marine waters in the wild they will thrive in a typical freshwater aquarium. A predatory fish, they will eat anything small enough to fit in their mouths although tend not to be aggressive towards tankmates.
