The Wolf Fish is one of the best known of all predatory characoids (other than the piranhas), although it is not seen with any great frequency. Like Hoplerythrinus unitaeniatus (the Golden Trahira), this species is widely distributed. One other species, Hoplias microlepis, is very occasionally available: it is somewhat smaller and comes from southern Ecuador, Panama, and Costa Rica.
