The gold wolf fish, Hoplerythrinus unitaeniatus, is a predatory erythrinid widespread throughout much of South America. Also known as the golden trahira, it inhabits small tributaries, swamps, marshes and forest lake margins, and can breathe air using a modified swim bladder. The only member of its genus to appear in the trade with any regularity, it is really a fish for the specialist and is intolerant of conspecifics.
