The Gold or One Lined Wolf Fish is a medium sized predatory species found throughout the Amazon Basin in South America. A fast moving and aggressive  fish, they are likely to attack even larger tankmates and are best kept alone or with large, fast moving fish or heavily armored catfish. Smaller specimens can be shy at first and appreciate plenty of cover, and be sure to keep their tanks tightly covered as they are prone to jump if spooked.
