The Mono Argentus, also referred to as Mono or Fingerfish, originates from the coastal and inland waters of Africa and Asia. This fish has a diamond shape, silver color, and two black stripes on its front half. Its dorsal fin has a yellow tint with a black outline. To accommodate their size, the Mono Argentus requires an aquarium of at least 50 gallons. While smaller specimens can survive in freshwater, a gradual transition to higher salinity is necessary as they mature. Aragonite sand or gravel substrate is preferred, along with plants and rocks that thrive in brackish water. Although the Mono Argentus spawns in the saltwater of the ocean, little is known about the difference between the sexes and their breeding habits. As juveniles they are mainly freshwater, and transition to salt as they get older, then completely saltwater as they mature. All our Mono’s are completely mature and are conditioned to saltwater In the wild, the Mono feeds primarily on vegetable matter. To maintain their diet, provide them with dried seaweed, lettuce, brine shrimp, and high-quality flake food. They are reef safe.
